little used favorite commands...

Todd McDaniel_1 — Fri, 12 Aug 2005 09:42:28 GMT

Okay, I am curious once more to find out what little used commands you have that are interesting and handy...

Basically my goal is to make us all aware of great little commands that most of us don't use on a daily basis...

I recently took a Posix coding class and learned of a few...

One I found very useful strangely interesting is "getopts" used in managing script command options and for formatting error messages for usage and such.

I frequently use getprpw & modprpw to deal with expired/locked out accounts.
The biggest pain with these is the lack of man entries in the OS itself - although you can get man pages online a www.docs.hp.com

Cheers,
Jeff

Bind version:

dig CHAOS TXT version.bind @some.dns.server

But you can change it in named.conf in the options section:

version "Wild DNS 1.0";

Sendmail version:

sendmail -v -d0.1 < /dev/null

The old favourite to find the size of processes:

UNIX95= ps -e -o vsz=Kbytes -o ruser -o pid,args=Command-Line | sort -rnk1 | grep -v Kbytes

Also tput, useful for making "pretty" output.

eg: -

clear
tput cup 5 10
tput smso
echo "Main Menu"
tput cup 6 10
tput sgr0
echo "Option 1"

Not really a command this:

man tunefs

Which I'm sure you're all aware of already.

I like it.

To checking machine status for whole day;

usr/sbin/sar -u -M > /logging/perf/`date +%b%Y`/cpu`date +%d` 2> /dev/null
/usr/sbin/sar -b > /logging/perf/`date +%b%Y`/buffer`date +%d` 2> /dev/null
/usr/sbin/sar -d > /logging/perf/`date +%b%Y`/disk`date +%d` 2> /dev/null

And for those who haven't seen it already, here's the link to your original thread on this one;

http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=406126

Here's a new one to go on the list

rev - reverses the lines in a file.

eg:

=> cat file1
one
two
three
four
five
six

=>rev file1
eno
owt
eerht
ruof
evif
xis

I'm sure there are endless applications for this, but personally, I used it to write a fake shell for April Fools Day :)

Heh well that was 18 months ago so I'm due a repeat!!

vg problems I love this one...

echo "0x2008?4D"| adb /dev/dsk/c-t-d-

the output gives you for each field, if I can ready my old notes:

1=address of lvm data
2=system/cpu id
3=pvid
4=system/cpu id
5=vgid

...I compare a disk that is in the vg and one that is reporting error (but should be in same vg)...if field 5 don't match that confirms the problem...

Rgrds,
Rita

usually forgottoen steps when repairing a failed root disk mirror:

rawdevice=/dev/rdsk/cXtXdX
mkboot -l ${rawdevice}
mkboot -a "hpux -lq (;0)/stand/vmunix" ${rawdevice}
cd /usr/sbin/diag/lif

then
mkboot -b updatediaglif2 -p ISL -p AUTO -p HPUX -p LABEL ${rawdevice}
else

display command used for filesystem creation:

# mkfs -m /dev/vgXX/lvolY

display contents of the superblock:

# fstyp -v /dev/vgXX/rlvolY

Moving all "*.arc" files to "*.old" in current dir:

# ls *.arc | awk -F"arc" '{system("cp "$0" "$1"old")}'

One I use almost every day: It shows the most recent files in a directory. I put it in my .kshrc file:

alias -x llast='ll -t | head -23' # ll most recent files`

Actually, this is a command I use a lot. It's the option for it that I don't use as frequently anymore. For the lp command, I always repeated the -o option each time. I discovered that I could put everything in single quotes.

So instead of
lp -dprinter -oduplex -otray3 -o3hole -onb
I do
lp -dprinter -o'duplex tray3 3hole nb'

Also, printing out man pages so that they paginate correctly
man man | lp -dprinter -on

I like the command
# strings /etc/lvmtab
to see the volumegroup entry in the lvmtab file.

Here's a few favorites:

whence (you'll never use which or whereis again)
type (even better than whence)

logins -d (a great security check)

ioscan -k (ultra-fast option)
ioscan -kfC lan (or disk or tape..)

addqueue (for JetDirect printers)

setboot (especially the SpeedyBoot options in 11.11)

Hi All,

I dont know any of this group have tried the command "yes"...this can be used to generate repeated outputs in a shell script. But I havent seen this used by any one yet. I think this is very rarely used.

eg:
#yes " How are you??"
How are you??
How are you??
How are you??
How are you??
How are you??
How are you??
How are you??
How are you??
How are you??
How are you??
How are you??
How are you??
How are you??
How are you??
How are you??
How are you??
How are you??
How are you??
How are you??
How are you??
How are you??
How are you??

Hi,

what about the following commands.
These are rarely used and can do special functions.

lock locks the screen ( try this :-)
doscp dos copy
split split a bigger file into small pieces.
ftpwho shows the ftp user info
fold formating the colum width. ( try fold -30 /etc/issue)
