Viewing Top Processes according to cpu, mem, swap size, etc.

I've wanted this for a long time, finally just sat down and came up with it. This shows you the sorted output of ps in a pretty format perfect for cron or startup scripts. You can sort by changing the k -vsz to k -pmem for example to sort by memory instead. If you want a function, here's one from my http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html aa_top_ps(){ local T N=${1:-10};T=${2:-vsz}; ps wwo pid,user,group,vsize:8,size:8,sz:6,rss:6,pmem:7,pcpu:7,time:7,wchan,sched=,stat,flags,comm,args k -${T} -A|sed -u "/^ *PID/d;${N}q"; } Show Sample Output

command ps wwo pid,user,group,vsize:8,size:8,sz:6,rss:6,pmem:7,pcpu:7,time:7,wchan,sched=,stat,flags,comm,args k -vsz -A|sed -u '/^ *PID/d;10q'

Shows users and 'virtual users' on your a unix-type system

Shows a list of users that currently running processes are executing as. YMMV regarding ps and it's many variants. For example, you might need: ps -axgu | cut -f1 -d' ' | sort -u Show Sample Output

The Hidden PS

While going through the source code for the well known ps command, I read about some interesting things.. Namely, that there are a bunch of different fields that ps can try and enumerate for you. These are fields I was not able to find in the man pages, documentation, only in the source. Here is a longer function that goes through each of the formats recognized by the ps on your machine, executes it, and then prompts you whether you would like to add it or not. Adding it simply adds it to an array that is then printed when you ctrl-c or at the end of the function run. This lets you save your favorite ones and then see the command to put in your .bash_profile like mine at : http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html Note that I had to do the exec method below in order to pause with read. t () { local r l a P f=/tmp/ps c='command ps wwo pid:6,user:8,vsize:8,comm:20' IFS=' '; trap 'exec 66 exec 66 $f && command ps L | tr -s ' ' >&$f; while read -u66 l >&/dev/null; do a=${l/% */}; $c,$a k -${a//%/} -A; yn "Add $a" && P[$SECONDS]=$a; done } Show Sample Output

find duplicate processes

This command will allow to search for duplicate processes and sort them by their run count. Note that if there are same processes run by different users you'll see only one user in the result line, so you'll need to do: ps aux | grep <process> to see all users that run this command.

List all Samba user name

Convert unix timestamp to date

The "-d" option for gnu's "date" command can calculate positive or negative offset from any time, including "now". You can even specify a source timezone (the output timezone can be set with the TZ environment variable). Useful! Fun! Not very well documented!

tar and remove files which are older that 100 days

tar does not have a -mtime option as find. tar appends all the file to an existing tar file.

locating packages held back, such as with "aptitude hold "

Numeric zero padding file rename

rename file name with fixed length nomeric format pattern

external projector for presentations

i spent way too many hours trying to fiddle with /etc/X11/xorg.conf trying to hook up various external projectors. too bad i didn't know this would solve all my problems.

find an unused unprivileged TCP port

Not really better - just different ;) There's probably a really simple solution out there somewhere...

Get a regular updated list of zombies

Shows all those processes; useful when building some massively forking script that could lead to zombies when you don't have your waitpid()'s done just right.

Show a random oneliner from commandlinefu.com

This will parse a random command json entry from http://commandlinefu.com A must have in your .bash_profile to learn new shell goodies at login!!!

Burn CD/DVD from an iso, eject disc when finished.

cdrecord -scanbus will tell you the (x,y,z) value of your cdr (for example, mine is 3,0,0)
