Retrieve args used to launch a process

We sometimes need to know which command line has been used to launch a process.

To retrieve the entire command, just issue: ps -p <pid> -o args and you will get:

COMMAND
<the command line used to launch the process>

If you need to parse it programmatically, just pipe it with sed: ps -p <pid> -o args | sed -n '2p' to retrieve only the second line.
