Find out current working directory of a process

eval ls -l /proc/{$(pgrep -d, COMMAND)}/cwd
This is an alternative to another command using two xargs. If it's a command you know there's only one of, you can just use: ls -l /proc/$(pgrep COMMAND)/cwd
Sample Output
$ eval ls -l /proc/{$(pgrep -d, vim)}/cwd
lrwxrwxrwx 1 splante 20000 0 Apr 14 09:25 /proc/11611/cwd -> /home/splante/p
lrwxrwxrwx 1 splante 20000 0 Apr 14 09:26 /proc/11680/cwd -> /tmp
$ sudo ls -l /proc/$(pgrep X)/cwd
lrwxrwxrwx 1 root root 0 Apr 13 18:31 /proc/3945/cwd -> /

What Others Think

The above command didn't work for me. I need to add the double quotation to make it work eval "ls -l /proc/{$(pgrep -d, bash)}/cwd"

Interesting. It works for me without the quotes on CentOS 5.5, bash v3.2.25(1) and OpenSUSE 11.4 bash v 4.1.10(1). It also worked on zsh 4.3.10 without quotes. What shell and version didn't it work on?

eval is not needed. Just type 'ls -l /proc/$(pgrep -d, X)/cwd'

chmurli, your version works if there is one process running for the command, in which case you don't need the "-d," either. If you notice, I had mentioned that in the comments. If there is more than one process, you need the curly braces and the comma, and you need the eval.
