Problem scenario
You want a given Linux user to be added to the sudoers group. You want the user to be able to use the "sudo " command before running other commands. How do you give the sudo privilege to a given user?
Solution
If you are using Debian or Ubuntu Linux, do this (but replace "cooluser" with the username of your choice):
sudo adduser cooluser sudo
If you are using CentOS/RHEL/Fedora, do this (but replace "cooluser" with the username of your choice):
Modify the /etc/sudoers file.
Find this stanza:
root ALL=(ALL) ALL
Add a stanza above it like this:
cooluser ALL=(ALL) ALL
