Sudo: Running as a specific user

Written by Benjamin Cane on 2011-08-20

Sudo is usually used to allow a user to run commands as root, but what happens if you want a user to run a command as another user?

You can use the example below to configure your sudo rule.

Example:

[[email protected] ~]$ sudo -u sudoguy whoami  
sudoguy

The rule from /etc/sudoers:

bcane ALL=(sudoguy) /usr/bin/whoami, NOPASSWD: ALL

Same thing but instead of bcane the users group:

%users ALL=(sudoguy) /usr/bin/whoami, NOPASSWD: ALL
