sudo uses the configuration file /etc/sudoers. This file has the following two modifications, which will take effect immediately after modification:
* Use the root account to run the visudo command and use the vi syntax to edit
* Use Echo adds configuration at the end of the file, such as:
'''echo "%monitor ALL=(ALL) NOPASSWD:/bin/netstat -nap" >> /etc/sudoers'''
2. Instructions for use
* List available sudo commands
Use a common account (such as monitor) to log in, and run:'''sudo -l'''
