Let's break it down:
- `usermod`: This is the command used to modify a user in Linux.
- `-a`: This option stands for 'append' or 'add'. It's used to add a new group to an existing user. Without it, the existing groups would be replaced, which is not desired here.
- `-G`: This option stands for 'group'. It's used to specify a user's group(s).
- `sudo`: This group name allows the user to execute root commands with the `sudo` command.
- `[user]`: Replace `[user]` with the actual user name that we want to assign to the sudo group.
For example:
`usermod -a -G sudo user1`
This will add the user `user1` to the sudo group. This means `user1` can use the `sudo` command to gain root privileges.
After adding a user to the `sudo` group, they will need to log out and log back in for their group membership to take effect. Alternatively, they can use the following command to reload the `sudoers` database immediately:
`sudo /etc/init.d/sudo reload` or `sudo systemctl reload sudo`
