Useful less-used Linux commands

1. lsb_release -a

2. The watch command.

3. Command line intro summary, with some rarely used switches (TLDP).

4. If you’re using a system which has a lot of users, and you’d like to see who has started a particular script, daemon, or binary, then the pstree utility is very helpful. It draws a tree of all currently running processes – allowing you to see which processes are related.
