In *nix you can use ps to see which process are running. But if an executable has multiple homonimous files in a device, we can't figure where it was invoked from.

This is slightly different from my last question on this subject. How can I know the absolute path of a running process?


Try this:

ls -l /proc/<PID>/cwd

Derived rom HUB's answer:

readlink /proc/<PID>/cwd

or even

readlink /proc/$(pgrep <program_name>)/cwd

You can't tell where a process was invoked from, only where it currently is. Look at the cwd ("current working directory") link instead of exe.

There are 3 methods that I'm aware of:


$ pwdx PID


$ lsof -p PID | grep cwd


$ readlink -e /proc/PID/cwd


I guess this command should work. It is a little workaround but it works at least on my machine.

for strlist in $(ps e PID);do if [ ${strlist:0:4} = "PWD=" ]; then echo ${strlist:4};fi;done


When I ran

ps auxwwwe | grep executableName > dump
vim dump

I was able to look for the part of the path I knew, and then I found out from which subdirectory the command was invoked from
