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.
[[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
