lsof should give all open files for a set of pids

Question

I have 30 instances of a process running on a server and want to log open files for each process for analysis.

I ran the following command:

* ps auw         


        

Answer 1

You can use xargs -L1 lsof -p to run lsof once per pid.

Even better: use lsof -c to list all open files from commands matching a specific pattern:

lsof -c bas # list all processes with commands starting with 'bas'
lsof -c '/ash$/x' # list all commands ending with 'ash' (regexp syntax)
