How to add a user to the sudoers list? Too many times asked this week so I have decided to write-up this simple how-to to my notes. There few different ways how you can carry out this, could be manual or by script. Manual way:
- change to root
- change directories to /etc
- allow to write to sudoers file which READ-ONLY by default
- add line with user in question and allow him to use sudo
su cd /etc ls -l chmod +w sudoers gedit sudoers --- scroll down in file and find line (root ALL=(ALL) ALL) --- ---- right there add this for the user (example userid: roman)--- root ALL=(ALL) ALL roman ALL=(ALL) ALL Exit & Save chmod -w sudoers (make the sudoers READ-ONLY again)
All is done and now user “roman” can use elevated right with use of sudo before the command.
However if you have too many users to add, it would make sense add them to group and and add the group to sudoers instead of all separate users 🙂 [easyazon-image align=”none” asin=”1118004426″ locale=”us” height=”160″ src=”http://ecx.images-amazon.com/images/I/51V033YDe8L._SL160_.jpg” width=”127″].[easyazon-image align=”none” asin=”B006WEHNCQ” locale=”us” height=”160″ src=”http://ecx.images-amazon.com/images/I/418p4pBQ1cL._SL160_.jpg” width=”106″].[easyazon-image align=”none” asin=”0132757273″ locale=”us” height=”160″ src=”http://ecx.images-amazon.com/images/I/51a52lDdQHL._SL160_.jpg” width=”129″]

You should review this post and invert commands
first you type chmod +w sudoers
after editing with gedit you type chmod -w sudoers
Thanks for correcting … fixed!
i am getting following warning :
[admin@localhost Desktop]$ sudo ./addsudoer.sh admin
sudo: ./addsudoer.sh: command not found
What Linux are you running ? Did you chmod a+x addsudoers.sh ?
Try to go to su and then execute the as a root,
