YMMV regarding ps and it's many variants. For example, you might need:

Save your open windows to a file so they can be opened after you restart

This will save your open windows to a file (~/.windows).

To start those applications:

cat ~/.windows | while read line; do $line &; done

Should work on any EWMH/NetWM compatible X Window Manager.

If you use DWM or another Window Manager not using EWMH or NetWM try this:

xwininfo -root -children | grep '^ ' | grep -v children | grep -v '<unknown>' | sed -n 's/^ *\(0x[0-9a-f]*\) .*/\1/p' | uniq | while read line; do xprop -id $line _NET_WM_PID | sed -n 's/.* = \([0-9]*\)$/\1/p'; done | uniq -u | grep -v '^$' | while read line; do ps -o cmd= $line; done > ~/.windows

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"; }

the executable that started the currently running oracle databases and the ORACLE_HOME relative to each

get a list of currently running oracle dbs (identified by the pmon process)

show the executable that spawned the process and

show the ORACLE_HOME relative to the environment within which the process is running

tailored to AIX (sed on linux behaves...differently)

suggestions for a better way...please.

Top ten (or whatever) memory utilizing processes (with children aggregate)

This command loops over all of the processes in a system and creates an associative array in awk with the process name as the key and the sum of the RSS as the value. The associative array has the effect of summing a parent process and all of it's children. It then prints the top ten processes sorted by size.

psgrep() { if [ ! -z $1 ] ; then echo "Grepping for processes matching $1..." ps aux | grep -i $1 | grep -v grep else echo "!! Need name to grep for" fi }

List users with running processes

This is different that `who` in that who only cares about logged-in users running shells, this command will show all daemon users and what not; also users logged in remotely via SSH but are running SFTP/SCP only and not a shell.

ptree equivalent in HP-UX

By setting the UNIX95 variable in HP-UX the XPG4 mode is activated, you get new options for ps and other commands, for me the best way to use this is to create an alias named ptree in root profile: alias ptree='UNIX95=1 ps -eH'

Wait for an already launched program to stop before starting a new command.

The '[r]' is to avoid grep from grepping itself. (interchange 'r' by the appropriate letter)

Here is an example that I use a lot (as root or halt will not work):

while (ps -ef | grep [w]get); do sleep 10; done; sleep 60; halt

I add the 'sleep 60' command just in case something went wrong; so that I have time to cancel.

Very useful if you are going to bed while downloading something and do not want your computer running all night.

Show the command line of a process that use a specific port (ubuntu)

A way not so simple but functional for print the command for the process that's listening a specific port.

I got the pid from lsof because I think it's more portable but can be used netstat

netstat -tlnp

ps -ef | grep user | awk '{print $2}' | while read pid; do echo $pid ; pfiles $pid| grep portnum; done

Find which process is using a port on Solaris

My old Solaris server does not have lsof, so I have to use pfiles.
