| + | Run a command as a specific user: | ||

| + | |||
| + | === Examples === | ||
| + | |||
| + | Let user alan run rdiff-backup as another user, not requiring a password: | ||
| + | |||
| + | < | ||
| + | alan ALL= (clientuser) NOPASSWD: / | ||
| + | </ | ||
| + | |||
| + | Let user alan run one command as root: | ||
| + | |||
| + | < | ||
| + | alan ALL= NOPASSWD: / | ||
| + | </ | ||
| + | |||
| + | Allow user '' | ||
| + | |||
| + | < | ||
| + | steve ALL=(beandog) NOPASSWD: ALL | ||
| + | </ | ||
| + | |||
| + | Set PATH for new user. sudo will not pass the user's PATH when switching to another user by default, which can cause problems if calling binaries in /usr/local. Override it with the secure_path option. | ||
| + | |||
| + | < | ||
| + | Defaults secure_path = / | ||
| + | </ | ||
