B = byte
b = bit

so what does MB mean ?  megabyte or megabit ???
and what is Mb?         Megabit ? Megabyte

Majority tends to say:
####################################
MB	Megabyte
Mb	Megabit
Mbps	Megabit per seconds
Netzwerk	100Mb/sec  <=> 12.5 MB/sec (=12.5 Megabytes/sec)
####################################

Bandwith measure in bits per second
------------------------------------
1Kb/s = 1000 bits per second
1Mb/s = 1'000'000 bits per second

Space measured in bytes and multipliers are power of 2
------------------------------------------------------
1KB = 1'024 bytes
1MB = 1'048'576 bytes
1GB = 1'073,741,824 bytes
####################################


always double check:
df -m			will say MB and actually means Mbytes
fx> label/show/part	states Megabytes	
diskperf		MB = Megabytes 
ftp			says Kbytes/s

Other:
------
FireWire
IEEE1394        400Mbit/s       50 MBytes/s
                800Mbit/s       
                1600Mbit/s
                3200Mbit/s

PCI bus bandwidth:
------------------
  33MHz, 64bit wide, 266 MB/s Theoretical bandwidth;
  66MHz              532 MB/s Theoretical bandwidth;

Unfortunately, you're both incorrect. Due to the implementation of
the Origin's XIO-to-PCI Bridge/Xbridge chip(s), the (X)Bridge will
"disconnect" DMA on every cache-line boundary, which casues a certain
fraction of the PCI bandwidth to be unavailable. On the O2000 this leads
to the *theoretical* maximum on a 64-bit/33-Mhz bus being ~213 MB/s
(not 266), and we've actually seen ~211 MB/s in certain test cases.

The same applies to Xbridge, so the *theoretical* maximum through
Xbridge to/from a 64-bit/66-Mhz bus is ~426 MB/s (roughly), though
I don't know what the max we've actually ever seen is. (A vague
memory says ~380 MB/s with some SCSI controllers, but don't quote me.)

pre6.4: scsicontrol
>=6.4 :  scsiha -p #
scsicontrol	probe and control scsi devices
		devices for the CDROM can be found in /dev/scsi
		when issuing scsicontrol no CD must be in CD driver
		if there is a CD mounted then the error message appears:
		sc0d4l0:  cannot open: Resource busy
Ex: scsicontrol -i sc0d4l0    (l0 stands for lun 0)
sc0d4l0:  CD-ROM        TOSHIBA CD-ROM XM-3501TA0095
ANSI vers 2, ISO ver: 0, ECMA ver: 0; 
Response format type 1, but has SCSI-2 capability bits set
supports:  reladdr.  inquiry format is SCSI 1

devnm name	identifies the special file associated with the mounted 
		filesystem



/dev/MAKEDEV	create device special files
		!!! first do "cd /dev " then "./MAKEDEV ......"
		MAKEDEV will create the device file in the current dir!!!
		./MAKEDEV plp

ioconfig 	IRIX 6.4  (ioconfig -f /hw ;reinitialize the hwgraph tree)
		-d add debuging output (ioconfig -d -f /hw)
sample for /etc/ioconfig to set SCSI bus differently on a O2000:
1051 /hw/module/1/slot/io5/mscsi/pci/1/scsi_ctlr/0

on O200 following line should work
103  /hw/module/1/slot/MotherBoard/node/xtalk/8/pci/3/scsi_ctlr/0

/etc/ioperms:
/dev/console 0644 root sys


flash		reprogram the flash PROM hardware on Origin and OCTANE machines
		-V Print currently loaded flash PROM version and time

see also FYI 100490 and the addition sent on August 27
Flash node from in PROM
>>flashcpu dksc(0,1,0)/usr/cpu/firmware/ip27prom.img

setdevperms - Update printing device entries in /etc/ioperms

Flash Octane from PROM:
flashcpu cdrom(0,4,7)/firmware/IP30/IP30prom.bin  # maybe option -o (overwrite) has to be used

TIB 200415 IP35 Cache Size May Be Set Incorrectly to 4MB
  If you find some nodes that are not 8 MB, you should reflash 
  them from the IRIX(R) operating system by using the -o option 
  with the following command line to override version checking:
flash -o -b <brick id>/usr/cpu/firmware/ip35prom.img

O3000/O3k l1 and l2 commands directly from Unix (starting with IRIX 6.5.15):
--------------------------------------
l1cmd - Send a command to the SGI L1 System Controller
	Ex:	# l1cmd env
l2cmd - Send a command to an SGI L2 System Controller

how do I check fan speeds" or voltages:
---------------------------------------
I know this is invading ESP-land but here is a cronjob I setup in the Peachtree
office,

2,17,32,47 * * * * test 32 -le `sysctlrd -p | grep "air temp" | awk '{print
$5}' | awk -F. '{print $1}'` && echo "Overtemperature condition in Peachtree
Lab" |
Mail -s "Overtemperature in Lab" zwrite@peachtree.sgi.com

Something similar can be created for the O3K.  This real example sends email if
32C is less than the reported temperature.

--------------
command ssmcli (storage processor command line interface) talks to the SP (storage
processor) in the Fibre Channel RAID ecnlosure. It communicates directly with the ssmagent.
ssmcli is an alternitive to the Raid GUI ssmgui.
ssmagent must be runnung - if no > ssmcli commands will fail
# chkconfig ssm on
# /etc/init.d/ssm start
 add in .login (or even better .cshrc) the path to
 set path = ($path /usr/ssm/bin /usr/ssm/lib)
or
 add in .profile 
 PATH=$PATH:/usr/ssm/bin:/usr/ssm/lib

ssmcli can be used to get various info about the RAID and can also be used to bind/unbind 
the disks.

Clariiion SCSI Channel RAID stuff:
------------------------------------
add following lines to /.login  (better .cshrc)
# complete path definition:
set path = ($path /usr/cluster/bin /usr/raid5)

raidgui		graphical raid interface
raid5		linked to raidcli

# raid5 getagent

see which disk is bound to which lun:
# raid5 -d sc5d8l0 getdisk |grep Lun
 or check all luns with
# raid5 -d sc5d8l0 getlun 0

get detailed info about disk A0:
# raid5 -d sc5d8l0 getdisk a0

Get the FRU info about disk:
# raid5 -d sc5d8l0 getfru c2

returns firmware (flare) revision and SP model number. 
NOTE: model 7624 = SAUNA controller and model 7305 = PHOENIX controller. 
# raid5 -d sc5d8l0 getsp

Which SP owns which lun ?
# scsifo -d
Group 8:
  [P] sc2d8l3 (82)
  [ ] sc5d8l3 (181)
Group 9:
  [P] sc2d8l2 (80)
  [ ] sc5d8l2 (172)
Group 10:
  [P] sc2d8l1 (71)
  [ ] sc5d8l1 (170)
Group 11:
  [ ] sc2d8l0 (62)
  [P] sc5d8l0 (168)


assign a certain lun to a certain SP
Ex: assign lun1 to go over SCSI bus 5 (SPB)
# scsifo -s sc2d8l1

Which SCSI bus belongs to which SP:
# raid5 getagent |egrep 'Name|Node'
Name: xl-raid3-SPA
Node: sc2d8l0
Name: xl-raid3-SPB
Node: sc5d8l0

Reassign Lun Ownership can also be done with 
# raidcli tresspass sc6d6l0 mine

Get 'Current' and 'Default' owner of a certain lun
# raid5 -d sc11d8l0 getlun 0 | egrep 'Current|Default'

Failover path:

If you try the command "scsifo -d", it should show you all pases to the
TP9400 Luns, with a p on the primary, the other pases is where the xlv 
fails over to in case of a failure on the primary path.

For this to work you need to have the xlvplex software installed; but you 
do not need the plexing license.

If you want to change the default selected pases, you need to enter a config
in /etc/failover.conf
_____________________________________________________________________________
/etc/failover.conf is only needed for JBOD, bandwidth solutions, and 3rd-party RAID
if using our RAID products the failover will happen automatically 240 seconds
after the 1st failed I/O request

ls -ld $HOME/tmp
drwxrwxrwt    3 nick     user         118 Aug  3 10:34 /usr/people/nick/tmp

man chmod ....
     If a directory is writable and the sticky bit, (t), is set on the
     directory, a process may remove or rename files within that directory
     only if one or more of the following is true (see unlink(2) and
     rename(2)):

          the effective user ID of the process is the same as that of the
          owner ID of the file

          the effective user ID of the process is the same as that of the
          owner ID of the directory

          the process is a superuser.

how to find these directories:	find . -type d -perm 1000 -print

setuid-bit setgid-bit
----------------------
setuid (4000)  
setgid (2000)
how to find these files:
find / -local \( -perm 2000 -o -perm 4000 \) -exec ls -l {} \;
_____________________________________________________________________________
ls -lh	show size more human readable, specially for large files
ls -u 	Use time of last access instead of last modification
		"file file.name " will change the access time of a file

Backup utilities:
==================
move trees from source_dir to target_dir:
cd source_dir
tar -cvf - . | (cd tartget_dir; tar -xpvf - )
	-p 	restores files to their original modes
		ignoring present umask. Setuid and sticky information 
		are also restored

cd /source/dir
tar -cvpBf - ./backup_dir | rsh root@<remhost> "(cd /target; tar -xpBf -)"

Just restore some directories from a tar archive:
tar -xvf sgiadm.tar sgiadm/bin sgiadm/configs
Note that this will restore the directory sgiadm/bin and sgiadm/configs
from the archive; also NOTE that there is NO terminating '/',
so the command "tar -xvf sgiadm.tar sgiadm/bin/" would not work
it would just restore the empry dir sgiadm/bin/ but none of the directories 
contents


xfsdump -l0 - /source_dir | xfsrestore - /target_dir

cp : new features for   1) Direct IO 
                        2) realtime filesystems

cp -D
cp -tP -e ......

Also df can now show you the realtime usage 
portion of the filesystem with the df -r flag

List_tape	List content of a tape written by Backup(1), cpio(1), 
		tar(1), or bru(1)


dump / restore
dump 0Cu 2m /usr	must include the C option followed by the size of the tape
			for example 2m (2Mbytes) otherwise it is constantly asking 
			for another tape

gr_nstats - NUMA Memory Management Statistics
dplace - a NUMA memory placement tool
ex.: dplace -data_pagesize 64k -stack_pagesize 64k a.out

dlook - a tool for showing memory and process placement
To show memory and thread placement for a  program called a.out that
     would normally be run by
        % a.out < in > out
     and place the resuls in a file called output one would simply
        % dlook -out output a.out < in > out 

-------------------------------------------------

bufview : file system buffer cache activity monitor
          the tool works like top or osview

-------------------------------------------------
Acces control lists / Capabilities
----------------------------------

While this is documented in a Pipeline article
here is the list of the new commands.

attrinit - Set file attributes -> neat tool since 
           it can read a script file.
           Take a look at the file /etc/irix.cap 
           you will be surprised.

chacl - change the access control list of a file or directory
        use the ls -D to obtain the ACL
        

chlabel - change the label of a file

chcap - change file capability sets
        use the ls -P to get the cap set
        try ls -P /sbin YOU WILL be SURPRISED.

will normally not work with cpr

Stop a process:
--------------
cd /var/tmp/cpr
cpr -c <statfile> -p <proc_id>
Ex:	cpr -c ckpt05Feb2002 -p 53711
Restart it:
-----------
cpr [-j] -r ckpt05Feb2002

How to find out the PGID of the process named standard.x:
 ps -efj |egrep 'PGID|standard.x'
cd /scratch/cpr; cpr -c ckpt05Feb2002 -p 537245:GID

-----------------------------------------------------------
How to speed up inst at exit:
...after install is done
inst > set rqs_task rqsread
inst > quit

man inst ...
If set to "rqsread", then only the first rqs phase will be
performed (the rqs registry file is updated).


But I don't know how to properly call rqsall(1) at a later time

Related commands and files:

To remove a single cache file have a look at the man page and the option
remove for nsadmin, or just try:

/sbin/umount /ns;/usr/sbin/nsadmin remove ;/bin/rm /var/ns/cache/*
;/usr/sbin/nsadmin restart

The man page suggests that the removal of a single map is possible so I
would try this first.

Or just from the unix prompt:
#sn0log -w -a > /var/adm/sn0log_date
this is to write the prom logs to a file

#sn0log -c -a
this is to clear the prom logs

comparison of OS command line / POD
sn0log -a -c 	= clearalllogs = Clear all log files. 
sn0log -a -i    = initalllogs = Initialize all PROM logs for all modules in the system;
		  resets PROM variables to factory defaults.

EX: To boot miniroot from disk:
# mkdir /disk/miniroot
# cp /CDROM/sa /disk/miniroot
# mkdir /disk/miniroot/miniroot
# cp /CDROM/miniroot/unix.IPXX  

Then you can boot miniroot from the prom menu
setting local directory /disk/miniroot

extract single files from inst package by installing to other root directory:
idea: install that product to another target (-r) and get it from that directory
	PRB 200261  
     The PROM can be manually installed on systems not running 
     6.5.10+ by downloading one of the patch files (#4153 or #4154) and using the 
     following steps: 
     
     1. Install the patch in an alternate root tree. 
     
     % inst -a -r/var/tmp/patch -f<path to extracted patch files> \
     -Vrulesoverride:on -Iall
     
     NOTE: You will need to add '-mCPUBOARD=IP32' if you extract the   
           files on a system other than an O2 system. 
     
     2. Install flash image (you must be root to do this). 
     % su
     # /sbin/flashinst -T -y -q \
     /var/tmp/patch/usr/cpu/firmware/ip32prom.image 
     
     3. Clean up the extracted files. 
     # rm -rf /var/tmp/patch

----------------------------
extract file io6prom.img

Using IRIX 6.5.11 Overlays [2 of 3] 812-0819-011

# grep usr/cpu/firmware/io6prom.img /CDROM/dist/eoe_6511f.idb
  f 0644 root sys usr/cpu/firmware/io6prom.img
  xlv54/6.5.11f/work/stand/arcs/IO6prom/SN0PROMio6prom.img eoe.sw.base sum(42196)
  size(367304) off(17655411) mach(CPUBOARD=IP27) cmpsize(0)
# inst -f /CDROM/dist/eoe_6511f -Y usr/cpu/firmware/io6prom.img -m
  CPUBOARD=IP27 -V rulesoverride:on -r /tmp -I default

;	 -r <target>;  -Y <file> Install only file during installations

Default distribution to install from: /CDROM/dist/eoe_6511f
.... proceed with inst dialog

# ls -R /tmp

extract ip27prom code (the next is all one line..)

% inst -f /CDROM/dist/eoe_6511f -Y usr/cpu/firmware/ip27prom.img -m
 CPUBOARD=IP27 -V rulesoverride:on -r /tmp -I default

 ->  When inst menu comes up type  'go'
 ->  When inst completes type      'quit'
%  ls -R /tmp   -> the prom image is in /tmp/usr/cpu/firmware

=================================================
other example how to if_eg.o from 6.5.14:
inst -U -r /var/tmp/removethis -f eoe_6514m -I eoe.sw.base -K '*'
will extract all files from eoe.sw.base to /var/tmp/removethis

-OR-
You can use showfiles:

cd /tmp
showfiles -f /CDROM_812-0818-014/dist/eoe_6514m -x
--usr/cpu/sysgen/IP27boot/if_eg.o
+ /tmp/if_eg.o

NOTE: To extract this file in IP27boot w/ showfiles, you have to be on a IP27 system.

Nice mechanisme to implement locking with hard links:
more than one processes should 
o check if a lock is set by creating a hard link


touch ./L.$$		# touch a tempfile with the own proc id
# try to link lockfile to L.$$:
ln ./L.$$ lockfile
# if successfull go on, do your tasks and at the end remove the file "lockfile"
# as long as this link is set, nobody else should be able to create such a link
# if not successfull stay in your loop and try again after a while
  
Ex:	
% touch L.1 L.2
% ln L.1 lockfile  	# successfully locked
% ln L.2 lockfile  	# lock will fail
May not unlink existing outplock  - Error 0
% rm lockfile		# release the lock
% ln L.2 lockfile	# successfully locked

Mail from Andy Heel:
"�" comes because your font does not support the euro symbol.

You need a iso8859-15 font (xlsfont | grep "iso8859-15" ),
and AFAIK you have to set LANG to your european Language.
(e.g. de_DE.ISO8859-15) (ls  /usr/lib/locale/)

If you need more fonts install x_eoe.sw.Xoptfonts.

Use cat euro.bin (attached) to test this.

Dual head:

I've been doing a little more investigation this morning and it looks like
the death grip interrupts the xdm parent process if you enter it on the
keyboard assigned to display 0. If you enter it on a different keyboard
that's assigned to another display, it interrupts only the child xdm
process that's assigned to that X display.

I also discovered that if I logout of X display 0's desktop, it also
terminates the other X display. I fixed this by changing the
DisplayManager._n.terminateServer:  statement to False in the
/var/X11/xdm/xdm-config file.

CONSOLE=/dev/ttyd1 --> root connection is only posible from console in serial port 1. No xterm root
connections are posible.

CONSOLE=noXlogin effectively prevents ANY�direct root-logins on the system.
Users must login with normal user names.
To gain root access users will have to use the su command.

with CONSOLE=/dev/ttyd1 you will be able to login as root on the "console serial port".

_____________________________________________________________________________
nm		print name list of an object file(s)
nm /usr/lib/libspaceball.a
typical linker error message:
ld:error 33: unresolved text symbol "dbtext" -- first referenced by usr/lib/
libspaceball.a (spaceball.o)
***error code 1 (BU21) 

elfdump		dumps selected parts of a 32-bit or a 64-bit ELF object file
elfdump -Dl <programm>	show used share objects
odump		dumps selected parts of an object file
file <executable> will show if it is a 32 N32 or 64 compiled image

Octal dump:
------------
od - octal dump
od -x 		Interpret words in hex.
od -c		Interpret bytes as characters
_____________________________________________________________________________
Networking stuff:
----------------
par		system call tracer
par -s -SS -p <pid>
par -SS -s -i -l -n 
par -siN open -l -SS /usr/Cadmin/bin/objectserver -d
par -isSS -l -o /tmp/os1.par /usr/Cadmin/bin/objectserver -l 7 -d
par -s -SSS -i -N write -a 4096 -b 4096 -o /tmp/output-file -p PID
   will trace process #PID and all its subsequent children.
   The arguments to write() system calls will be logged, including up to
   4096 of ascii (a) or binary (b) data from the buffer given to write()
par -rsSSQQ -o inst
par -ilsASSQQQ -o /tmp/date_a date 10


traceroute	print the route packets take to a network host
ping		send ICMP ECHO_REQUEST packets to network hosts
		ping -c 1 -R <targethost_name>  show routes (-c counts)
netstat		show network status
		-r show routing
netstat 5	# show packet status every 5 seconds
		# first line shows the total, further lines show delta
		# perfect to watch if we have further collisions

		netstat -ia 2
		netstat -I ec0 2
		netstat -s -p tcp
		netstat -C  
     To match a socket to a process, the fuser(1M) command can be used.  For
     example, the command

          fuser 25/tcp

     will display information about any processes listening on TCP port 25.
     Note that fuser requires the numeric value for the port, not the name of
     the service.  The -n option will force netstat to display service
     information numerically.

route		manually manipulate the routing tables
route add default <IP-addres_gateway> 1 ????????
Ex: 	route add -net <destination> <gateway>
	route add -net 193.187.200 193.187.248.100
add it permanently to /etc/config/static-route.options

add default route to gateway 144.253.153.1:
route add -net default 144.253.153.1

route -n monitor	# monitor any changes in the routing table
			# normally nothing happens

# Very useful when we want to know through which interface we go
# when connecting to a remote system:
route get <hostname>	# get info about the route to that host
route get <IP-address>

smtstat		show FDDI SMT status
smtstat -C	# check 5 for neighbourhood (or use fddiviz)
nslookup	query Internet name servers interactively
nslookup > ls -d zurich.sgi.com		# dump the whole map
 nslookup -query=mx sgsc 
or
 nslookup > set querytype=MX
> eggenberger.org
eggenberger.org preference = 10, mail exchanger = mail.eggenberger.org

Authoritative answers can be found from:
eggenberger.org nameserver = DNS.NETSTREAM.CH
eggenberger.org nameserver = DNS2.NETSTREAM.CH
mail.eggenberger.org    internet address = 207.154.76.249
DNS.NETSTREAM.CH        internet address = 62.65.128.10
DNS2.NETSTREAM.CH       internet address = 62.65.128.15




netsnoop	capture and decode network traffic (like snoop on SUN)
/usr/sbin/netsnoop -vvv "(ip.src == 195.10.101.49)||ip.dst == (195.10.101.49)"

		IRIX 6.2 (PART 1 OF 2) eoe.sw.ipgate
snoop 		similar to netsnoop but for IRIX 6.3 and later (nfs.sw.nfs)

snoop -o snoopfile.out  <host> <host> rpc ypserv 	capture all rpc packets between the 2 hosts
snoop -v -i snoopfile.out	look at the file snoopfile.out
snoop -o /var/tmp/snoop.out arp		look at all arp broadcasts
snoop port 25	watch the mail port (defined in /etc/services)
snoop port 53	watch DNS queries (find out who is dnsserver)
snoop -d lo0 rpc nfs	watch nfs queries on loopback interface (also see /etc/rpc)
snoop rpc mountd	watch how partitions get mounted and umounted
snoop -o /tmp/snoopfile.out 192.2.3.4  192.3.2.4
	Truncate each packet after snaplen bytes -s <snaplen>
	save lot of disk space
	snoop -o /tmp/snoopfile.out -s 140

snoop -d eg1 "lion not mahagoni"	# watch traffic on interface eg1
					# snoop all packets from or to lion
					# disregard packets from or to mahagoni

snoop "not pinky not punky"		# snoop all packets except for pinky and punky
http://www.enteract.com/~lspitz/snoop.html

look at the captured snoop packages:
snoop -i /tmp/snoopfile.out			get overview
snoop -i /tmp/snoopfile.out -V			verbose overview
snoop -i /tmp/snoopfile.out -v -p 10,15		look at packets 10-15

rpcbind
rpcinfo -p <hostname>
rup		show host status of local machines (RPC version)
		rup -l <hostname>
proclaim	client for Dynamic Host Configuration Protocol (DHCP)
portmap		TCP,UDP port to RPC program number mapper
		(Not for ordinary users)
arp		address resolution display and control
		arp -a ( before issue a ping <broadcast.address>
		looked up by ifconfig ec0)
arp -av		show add. info such as the interface associated with entries and age of the entry

ttcp usage:	one host will send, the other will listen
on the transmitter host:
# ttcp -t -s -fm <reciever-host>
on the reciever host:
# ttcp -r -s -fm
	-fm means result in the format (f) Mbit/sec (m)

basic network files:
--------------------
/etc/sys_id, /etc/hosts, /etc/config/ifconfig-?.options (netmask)

/etc/protocols, /etc/services, /etc/networks, /etc/gateways
/etc/resolv.conf
/var/yp/ypdomain (NIS) (if NIS domain != internet domain)

_____________________________________________________________________________
Compress and uncompress:
------------------------------
pack,pcat,unpack	compress and expand files (Huffman coding)
gzip, gunzip		compress and uncompress files
			Gzip uses the Lempel-Ziv algorithm used in zip and PKZIP
compress		(LZW-algorithm)
zip,unzip		fw_IZzip.sw.zip         usr/freeware/bin/zip
			works fine for archives compressed on NT

tar cf - nsmail | gzip -c | crypt my_secret_password > nsmail.packed

cat 		-v 	print non ASCII Charachters

File Transfer via email:
-make package with tar (cd /source/dir ; tar -cvf source.tar ./dir_or_file)
-compress source.tar  (will create source.tar.Z)
-make a ASCII version out of it
 uuencode source.tar.Z source.tar.Z > source.tar.Z.uu
- this can be sent as an attachment via email
   ex: mailx -v -s "sending source.tar.Z.uu" nick@sgi.com < source.tar.Z.uu

to unpack :
-save attachement as /any/dir/source.tar.Z.uu
-uudecode source.tar.Z.uu
-uncompress source.tar.Z ( ->source.tar)
-tar -xvf source.tar

_____________________________________________________________________________
Formating
---------
tr		translate characters
		Ex: tr -d "[\200-\777]" < filename > filename2
		delete all control characters in "filename"
		cat xx | tr -s "[a-z]" "[A-Z]"  (convert all lower to upper)
get rid of the ^M in a file (saved with Netscape)
cat -v file.txt | tr -d /^M/ > cleanfile.txt
or better:	cat file.txt| tr -d '\015' > cleanfile.txt
do the same job in vi:
  :g/^M/s///g		(^M has to typed as '<ctrl><v><m>')
	and another solution:
sed 's/^V^M//g' foo > foo.new


  convert from Macintosh file to Unix Ascii (Mac files contain lots of ^M)
	#Octal: \015 (^M CR Carriage Return) ; \012\ (^J LF Line Feed) 
  cat file.txt | tr -s "\015" "\012"	

show each directory of PATH on seperate directory:
alias pa 'echo $PATH | tr -s "[:]" "\n"'

cut -d<delimiter> -f<field>
cut -d":" -f3 /etc/passwd	print all UID's of /etc/passwd
cut -d":" -f3 /etc/passwd | sort -n | uniq
cut -d":" -f3,1 /etc/passwd	also show the username

cut -c0-20 <file>	print character 0 until 20 of each line in <file>
			first character is 0
sed
Ex:
1.) /usr/etc/netstat -ia | grep 08:00 | sed 's/ *//;s/://g' | head -1 | tr '[a-f]' '[A-F]'

2.) nvram | grep eaddr | cut -d= -f2 | sed -e s/://g | tr '[a-f]' '[A-F]'

3.) sysinfo | grep -v System | sed 's/00//g' | sed 's/ //g;2s/^/0800/' | tr '[a-f]' '[A-F]'

paste	merge same lines of several files or subsequent lines of one file

4.) replace in /etc/fstab the word vol_usr with vol_usr_plex:

 sed 's/'vol_usr'/'vol_usr_plex'/g' /etc/fstab > /tmp/fstab.cloned
the serach patterns can also be replaced by variables:
sed 's/'$xlv_usr'/'$d3_xlv_usr[$nxlv]'/g' /etc/fstab  > $tmpmnt/etc/fstab

same function can be implemented with perl see also UGU:
perl -p -i -e 's/original text string/replacementstring/g' <filename>

list perm, size and name:
ls -lt | tr -s " " | cut -d " " -f1,5,9
drwxrwxr-x 103 develop
-rw-rw-r-- 6639 examples.html

sed replace string:
sh:
VARIABLE=nick
echo "hallo world" | sed -e s/world/$VARIABLE/g
  hallo nick

csh:
set VARIABLE = nick
echo "hallo world" | sed -e s/world/$VARIABLE/g
 hallo nick

guenstig um das in einer Schlaufe zu verwenden

man ascii	map of ASCII character set /show ASCII Table
_____________________________________________________________________________
Trouble to remove a special file:
---------------------------------
ls -i		list file by inode
clri		clear inode (elete file by inode)
		should only be used for efs filesystems
		for xfs filesystems use xfs_check and xfs_repair(repeatedly)

Filesystem repair:
-----------------
xfs_check
/usr/sbin/xfs_repair	(comes with patch1422 in IRIX 6.2)
xfs_repair  /dev/rdsk/dks0d2s0     do it on the raw device

		
_____________________________________________________________________________

Memmory and processes:
----------------------
pmem		report per-process memory usage (/usr/sbin/pmem)
		belongs to package "pcp.sw.monitor /Performance Co-Pilot for IRIX 6.2, 1.2"
ps 		report process status
gmemusage	graphical memory usage viewer
gr_osview	graphical system monitor
osview		ASCII system monitor
gr_top		display processes having highest CPU usage in a window
top		display processes having highest CPU usage
top -o mem	sort processes by size of memory used
xload		CPU load with history

sar	
# sar -f /var/adm/sa/sa01	What was the system activity at the first of this month ? only for root
# sar -d -f /var/adm/sa/sa21 -s 07:30 -e 09:30
  show disk activity (-d) on 21st of this month between 07:30 and 09:30

Sar data is collected by crontab of user sys with script /usr/lib/sa/sa1 (every hour)

_____________________________________________________________________________
more about sar:
----------------
best to watch system for a certain period and save all data into a file
sar -A -o /var/tmp/sar.log 10 5
 -A all options combined
 10 delay of 10 seconds
 5  take 5 samples

then look at all the details by reading from that log:
sar -U -f /var/tmp/sar.log	# per CPU utilization, similar to -u
sar -D -f /var/tmp/sar.log	# Disk
sar -w -f /var/tmp/sar.log	# swap

more about top:
---------------
use the option '?' within top; Ex press 'o' and type 'res'
 this will sort the processes by RES memory size
 can also be achieved with command:
top -o res

Print from NT to Unix:
----------------------
Samba printing does not work as smooth as expected. 
To print on SGI paper on the hp4050 do the following:
On NT:
o print document, but use 'print to file'
o save the file on UNIX

Now put in the desired paper in TRAY 1
on UNIX:
o lp -d hp4050_tray1 -o raw <your_filename>

Printing troubleshooting guide:
----------------------------------
I. Uninstall and then reinstall all of the print.sw stuff

II. Enable debug in the interface script, look in the directory 
/var/spool/lp/interface, you should see files that are named the same as 
any printers you created.

	1. Edit the file in question.  At the top of the file you will see 
         a line that looks like this:

		#!/bin/sh

	   Change it to look like this:

		#!/bin/sh -x

	   Save the change and exit the editor.

	2. Try to print something short and simple:

		cat <filename> |lp -d<printer_name>

		cat /etc/hosts |lp -dsgiprinter

	3. The debug output should end up in the /var/spool/lp/log file and 
         look like the script commands executed.

	4. Print with the debug option 'verbose'
		lptest >/tmp/testfile
		lp -d<printer_name> -o"verbose" /tmp/testfile

III. Make sure you have the following subsystems install.
	1. do a versions |grep impr_   
		output should  show -  impr_print.sw.laserjetPS, impr_base.man.impr,
		impr_base.man.relnotes, impr_base.sw.impr, impr_base.books.Impr_UG,
		impr_print.man.impr plus any others you may want to include.  
		
	2. Check out the Impressario release note for more info  
         (grelnotes impressario).

      To test connection for a IP addressable printer check out the following:


IV. One test to try is telnet to the IP address and port number of the 
     printer.
		Exp: telnet 128.120.27.14 9100  ( or 515 -std bsd port)

		where 128.120.27.14 is the IP address and 9100/515 is the 
		port number.  If that succeeds w/o error messages. You should 
  		see something like:

			$ telnet 150.166.144.35 9100  -OR-  telnet 150.166.144.35 515
			Trying 150.166.144.35...
			Connected to 150.166.144.35.
			Escape character is '^]'.           # this indicates a 
                                                        connection

			^]                                 # type 'Ctrl ]' to break the 
                                                       connection

			telnet> quit                       # then 'quit' to exit
			Connection closed.


	Check the printer documentation to make sure which network port the printer
	is listening on.  If necessary either change the configuration inside the
	printer to conform, or modify /var/spool/lp/interface/<prtrname> to use a
	port that matches the printer as in the following excerpt from one of the
	networkable model files:

		---
		# Network port to write to.  9100 is HP Jetdirect card and EX.
		# The JetDirect 3Plus EX uses 9100, 9101, and 9102 for ports 1, 2, and 3.
		# Many other vendors use same port as HP.  OUTSOCK is port to write to.
		# INSOCK is socket to read for status (for future use -- status
		# now read from same socket address as specified a by OUTSOCK).

			OUTSOCK=9100
			INSOCK=9100

The good general test is to take a file that should be printable by the printer, 
ie: /usr/lib/print/data/testprint.ps for a postscript printer and 
then: "cat /usr/lib/print/test.ps > /dev/plp".  This will bypass all the printing 
spooling stuff and blow the file right out the parallel port to the postscript 
printer, and if the basic hardware is ok it should print it.

How to resize your window to a certain size (xwsh):
 echo "\033[203;3;80/y"		# resize it to 3 lines 80 coloumns
 echo "\033[203;80;100/y"	# 80 lines 100 coloumns

more explained in detail:
>From the manual page xwsh
     CSI Pv m

     describes a sequence that begins with CSI ("control sequence introducer")
     followed by zero or more semicolon separated numbers followed by the
     character "m".  ESC ("escape") expands to "\033".  CSI expands to either
     "ESC [" (escape left-bracket) or to "\233".  DCS ("device control
     string") expands to either "ESC P" (escape capital-P) or to "\220".  ST
     ("string terminator") expands to either "ESC \\" (escape backslash) or to
     "\234".

So the CSI is documented to be "ESC [".  To resize the window:

      CSI Pv / y  xwsh command.  The first parameter to this escape sequence
                  is the particular command described in the table that
                  follows.  Each command has different numbers of arguments
                  which are described below.

           203  Set the window size by row and column.  This sequence takes
                three parameters.  The first is 203.  The second parameter is
                the number of rows to use.  The third parameter is the number
                of columns to use.

So to resize to 60 columns and 30 rows, you'd do

        echo '^[[203;30;60/y'

Here '^[' is the rendition of the ASCII escape character.  It depends a bit
on your shell how you can access it.  Control-V ESC is a good bet with many
shells.

Sendmail:
==========
sendmail		send network mail
mailq			show mailqueue status
vacation		send mail to users or read mail
mailbox			mail notification
xbiff			mailbox flag for X

after you modify the sendmail.cf, you should do the following:
/etc/init.d/mail stop
/usr/lib/sendmail -bz
/etc/init.d/mail start

how to delete mails which can not be delivered:
	# /etc/init.d/mail stop
	# rm /var/spool/mqueue/r.... /var/spool/mqueue/d....
	# /etc/init.d/mail start

check for /etc/aliases the line:
#+:+     if you are using NIS

after changing /etc/aliases issue:	newaliases

versions of sendmail:
telnet localhost 25
220- lion.zurich.sgi.com Sendmail 950413.SGI.8.6.12

Vacation message setup (from Peter's help page)
-----------------------------------------------

Traveling & Vacation Messages This tutorial tells you how to set up vacation 
messaging for your email. This way when people send you email and you are out 
of town they will get a message to that effect. 

1. In your home directory create a file .vacation.msg that has your vac. mesg. 
    with:

    From: ...
    Subject: I'm on vacation
    Precedence: bulk

2. In your home directory create a file .forward containing the following line: 
     \username, "|/usr/sbin/vacation username" 
     Note: replace username in the above example with your login name 
3. To activate this message, in a shell window type: 
     vacation -i -r 1 
     (this is the number "1" for 1 message per day) 
4.To deactivate, when you return, move .forward to another location to save it 
     mv .forward .forward.save 
5. To reactivate (next trip) edit .vacation.msg and move the .forward file back 
     mv .forward.save .forward 
6. To test, send yourself an email and see if the vacation program replies correctly
7. For more information, read the man page on vacation 


How to add logging for certain mail aliases
--------------------------------------------
add the alias in /etc/aliases (/etc/aliases.yp)
# grep "^support^ /etc/aliases.yp
support:michi, "|/usr/local/bin/savesupport"
# cat /usr/local/bin/savesupport

#!/bin/csh -f
cat >> /usr/local/savemail/support
exit

# ls -l /usr/local/savemail/support
-rw-r--r--    1 guest    guest .....	# should belong to guest 
					# under 6.2 it did not work otherwise

How to redirect Mail to null ?
------------------------------
in /etc/aliases (or /etc/aliases.yp for NIS)
keak: /dev/null

dont forget to issue 'newaliases' afterwards !!


How to send mail to more than one person:
-----------------------------------------
cat $HOME/nick/.forward
nick
nick@hotmail.com

# don't use the back slash \nick@hotmail.com as suggested in the 
# description for vacation

Serial Devices:
--------------
setup a terminal:
HW:  connect serial line 2 of workstation to server serial line 1
SW:  on workstation change /etc/uucp/Devices
     uncomment the line with "Direct ttyd2 - 9600 direct"
CMD: to connect to server do a "cu -l ttyd2" on the workstation
of course eoe.sw.uucp has to be installed

_____________________________________________________________________________

mkfp	is a formatting/partitioning utility that can be used to create DOS
	and HFS file systems on devices such as floppies, flopticals, SyQuest,
	Jaz, PC Cards, Zip and hard-drives.
_____________________________________________________________________________
User and accounts:
------------------
/etc/autolgin
/etc/autolgin.on
/etc/default/login
man xdm

check /etc/passwd and /etc/group if setup correct:
al pwck
grpck

/etc/capability		user capability database (check with id -P)

Standart files (skeleton)
starting with IRIX 6.5 new location
 /var/sysadm/config/default.{cshrc/login/profile}
old location (pre 6.5)
 /etc/std{cshrc/login/profile}

To add a user with a command use
/usr/sysadm/privbin/addUserAccount		see man page which explains which
	other scripts are run and what skeleton files are copied to that home dir
_____________________________________________________________________________
PATH path variable:
---------------------
csh tcsh:
 add in .login the path to (better to set it in .cshrc because .login
  will not be sourced when only executing rsh)
 set path = ($path /usr/ssm/bin /usr/ssm/lib)
 set path = (. $path)		# add . to path; sec hole

sh, ksh
 add in .profile
 PATH=$PATH:$HOME/bin
 PATH=:$PATH			# add . to PATH; sec hole

Accounting:
-----------
acctcom -u <user>	eoe.sw.acct  (chkconfig acct on)
eoe.{man.sw}.audit	(Audit trail software)
quot /d2		summarize filesystem ownership ; disk utilization by user
quot -a
_____________________________________________________________________________
Security:
-----------
crypt <key> <xx >xx.encrypted
		encript xx with the key abc and write it to file xx.encrypted
Ex:		crypt abc <xx >xx.encrypted
		To decode the encrypted file:
		crypt abc <xx.encrypted	
_____________________________________________________________________________

_____________________________________________________________________________
NFS automount and autofs
--------------------------

autofs	master map /etc/auto_master	(man autofsd | autofs)

	Do not kill autofsd to change the AutoFS configuration. 
	Run the autofs command to cause changes in the configuration 
	maps to take affect. 
_____________________________________________________________________________
Shellscript stuff / Editor
---------------------------
dirname /var/adm/SYSLOG		-> /var/adm
basename /var/adm/SYSLOG	-> SYSLOG

basename string [ suffix ]
basename filename.ps.Z .Z	-> filename.ps
basename filename.ps.Z .ps.Z	-> filename
basename filename.ps.Z '.ps.Z'	-> filename

printf 		print formatted output
read		Read from a file
Ex:	printf "\aPlease fill in the following: \nName: " 
	read name
	printf "Phone number: "
	read phone
sed
echo '16i[q]sa[ln0=aln100%Pln100/snlbx]sbA0D4D465452snlbxq'|dc
awk:
# foreach f ( `showprods -nD1 | grep patchSG | awk '{print $2}'` )
? echo $f
? end

Sort /etc/passwd by ascending UID:
awk -F: '{print $3,$1}' /etc/passwd | sort -k2 -n
OR
awk '{ FS=":" ; OFS="\t\t"; print $1,$3}' /etc/passwd | sort -k2 -n
OR
cat /etc/passwd |awk -F: '{printf ("%8s\t%13s\t%3s\n",$3,$1,$5)}' |sort -k1 -n
sort -t: +2n -3 /etc/passwd

archive only regular files in a directory, ommitting subdirectories and hidden files:
ls -al | awk '$0!~/^d/ {print $9}' | xargs tar cvf archive_name.tar
	      ^^^^^^^ means ignore lines where the entire line ($0) starts with a "d"


versions -nb |grep patchSG |awk '{print $2}' |cut -c11-14
compare directories after copying a tree:
	cd /source_dir; ls -lR | awk '{print $5,$9}' > /tmp/list_source
	cd /dest_dir; ls -lR | awk '{print $5,$9}' > /tmp/list_dest
	then compare the 2 files /tmp/list_source /tmp/list_dest

Print size and name of file with a preceeding "o"
% ls -l | awk '{print "o",$5,$9}'
o 10390 MotOGLDump.c
o 61246 v_indy.txt

select all emerg(0) alert(1) and crit(2) messages from  /var/adm/SYSLOG
awk '$4~/[0-2][A-X]:/ ' /var/adm/SYSLOG
awk '$4~/[0-2][A-X]:/ ' /var/adm/oSYSLOG
+------------
 explained:
 awk 'pattern { action }'   #if there is no action defined then the whole line is printed
 in above example we do pattern matching with the fourth element and check if
 it contains the digit 0-2 [emerg(0) alert(1) crit(2)] followed by any letter
 (representing the facility) followed by a ":"
 a typical line in SYSLOG looks like this:
Aug 16 09:59:26 1T:lion nick: another logger_test
+------------

delete empty lines in a text file:
---------------------------------
awk 'NF>0' <text_file>
	or
sed '/^$/d' <text_file>


print line 20 to line 30 of a file:
-----------------------------------
sed -n '20,30p' <textfile>
_____________________________________________________________________________
Join files together:
task:	join the 2 files together
% cat x
2178557
2179065
% cat y
glXCreateGLXPixmap function call generates a BadAlloc
Networker does not write tapes to full capacity

% cat -n x > xn ; cat -n y > yn		
	#this will add number for each line
% join -1 1 -2 1 -o 1.2,2.2 -t : xn yn
	# join file xn and yn comparing by the first field of each file 
	# field one from file 1  (-1 1)
	# field one from file 2  (-2 1)
	# write to stdout field 2 of file one (1.2) and field 2 of file 2 (2.2)
	# as field separator take the ':' sign
the command will result in:
2178557:        glXCreateGLXPixmap function call generates a BadAlloc error
2179065:        Networker does not write tapes to full capacity

O2 uppgrade to 5200 CPUs
------------------------

Upgrade prom before replacing the CPU!
Remember diskcloning newer flashes the proms.


Check Prom version: 
On booted system use: 
strings /usr/cpu/firmware/ip32prom.image | grep VERSION 
(must be 4.12 or higher, this image is copied when cloning) 
 
This checks the version of the PROM image at: 
/usr/cpu/firmware/ip32prom.image 
 
If incorrect Run following command: 
 
/sbin/flashinst -T -y /usr/cpu/firmware/ip32prom.image 
 
If system will not boot, you will have to swap the customers old 
CPU back onto Systemboard. Then boot the system up and do the above command.

 
If customer does not have the Old CPU, try replacing the Systemboard. 
Newer Systemboards are supposed to be using Prom Version: 4.11 or 
higher and this should let you at least get to miniroot.
