How to add a comment or a remark for a user in Linux?
Published July 31, 2021
To add a comment or a unique remark for a user, you can use the
usermod command followed by the
-c (comment flag), then followed by the comment in quotes, and then specify the name of the user to add the comment in Linux.
For example, let's say we have a user called
john who is the system administrator. So we can add a comment of
Administrator for the user
john in Linux.
To do that we can use the
usermod command like this,
# Add a comment for a user sudo usermod -c 'Administrator' john
- Sometimes you may need to use the
sudocommand before the
usermodcommand to obtain the correct privileges to execute the command.
Now if you look at the output of the list of all users using the
cat /etc/passwd command in Linux, you can see that the
john user has a comment called
Administrator attached to the user.
It may look like this,
# Output of the /etc/passwd file # ... john:x:975:975:Administrator:/:/usr/bin/nologin # ...
Try executing the above command in this online terminal to see the result.
