What a linux command take the result of "which" command as an argument and list the configuration file paths related to the command we gave to which?

I can't recall that command and I can't even find it in Google. It's just killing me. The usage of the command is like: which bash The output looks like: /etc/skel/.bash_logout /etc/skel/.bash_profile /etc/skel/.bashrc Took bush just for example of course. It may be any command. Upd: I use the Redhat based OS.
