ps -ef | grep processName

What? like, I have the process number. I just want to see if it is working.

What do you mean by saying if you want to see if the process is working?

If you have the process number, just do 'top' in a terminal and see if that process is running. You cant get an idea if the process is running properly from here.

but I want do a script that:

First: executes a svn command and stores the process number in a var
Second: executes a zinity command, which in my case is a process bar
Third: checks with an if, if the svn command is done (or if you prefer not running) and kills the zinity bar.

this is from here


if you know the process id, then check if a directory with that id exits in /proc/

easily done in python

if os.path.exists("/proc/"+processID):

or else in a shell script

if [-d $DIR]
