CPanel: Granting Shell Access

Grant jailed-shell access via WHM as well to any of your cPanel users.

Jailed shell access is more secure as users will only be able to modify files owned by them.
Users will also not be able to execute commands that can be potentially harmful to other users on the server from jailed-shell.

It can be enabled on a per-user basis via WHM > Account Functions > Manage Shell Access
