8~osstat, $2~pid, $11~cmd
Shows a tree view of parent to child processes in the output of ps (linux). Similar output can be achieved with pstree (also linux) or ptree (Solaris).
Probably posted previously, I use this all the time to find and kill a process for "APP". Simply replace "APP" with the name of the process you're looking to kill.
I like to make it an alias in my .bashrc file, as such:
alias psme='ps -ef | grep $USER'
Kill all processes with foo in them. Similar to pkill but more complete and also works when there is no pkill command.
Works on almost every Linux/Unix platform I have tried.
ps returns all running processes which are then sorted by the 4th field in numerical order and the top 10 are sent to STDOUT.
