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.

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

Can use lsof, but since it's not part of the base OS, it's not always available.
