comment How can I use chmod to remove permissions for specific folders or file in my directory?
@eyoung100, a) there is no /etc/groups. there is /etc/group. b) Normally it has read permission for all. No need to use sudo. c) no need in cat. you can simply grep nobody /etc/group. d) how chgrp to nobody can help here?

@evilsoup, updated. May be I'm not the best explainer, though I hope it will be clear now.

There is no -P option in ssh. $ man -P 'cat' ssh | grep -- -P | wc -l # --> 0
