Handy sudo Settings
Defaults passprompt="%u@%h's password: " Defaults timestamp_timeout=15
The first line changes the password from something generic:
% sudo whoami Password: root
To something a lot more useful:
% sudo whoami dave@fuji's password: root
The second line changes the time between needing to re-enter your password from 5 minutes to 15 minutes. This is handy if you’re confident you’re in a fairly secure physical environment, like an iMac at home, and you find
sudo asking for your password too frequently. If you work in a more paranoid physical environment, you may want to keep the timeout at 5 minutes.
Remember to edit the file with
visudo(8). Don’t edit it directly.
% sudo EDITOR=emacs visudo
