visudo edits the sudoers file in a safe fashion, analogous to vipw(8).
visudo locks the sudoers file against multiple simultaneous edits,
provides basic sanity checks, and checks for parse errors. If the
sudoers file is currently being edited you will receive a message to
try again later.
The lock file used is the specified sudoers file with ".tmp"
appended to it.
