Deleting User in Red Hat Linux


Dear all,

I am sorry and i am not sure if this is the right category to post this qns.

Basically i have added a few users using the command:

e.g useradd alice

I accidentely deleted the user using:

e.g userdel alice and not using userdel -r alice.

when i use ls , i realise that the users are visible but the systems says users do not exist.

May i know how to get rid of the users?

I think user is now locked, unable to log in, but the files are still there, you need to remove home dir and other files also (owned by alice)

no, rmdir /home/alice would be better. do not remove /home! be care about removing anything, it can be dangerous!

delete home dir

hi there,

The rm -r /home/alice worked.. but the problem is that i have to type y for all the files that are deleted.

Is it possible to force delete all the users without selecting y or yes all the time?

Try this:
Code:
rm -rf /var/spool/mail/alice
In the future when you delete a user, make sure to include the -r option with the userdel command as this will remove the home directory and user's mail spool (that is, if you want that to happen).

I've never had to do that before, so I'm not really sure if there's a command to do that. Depending on the number of users in your system, I'd write a script to purge their mail spools one by one.

Just be sure to be careful when you do this (if you do this in a real world situation) because without proper backups it's 100% assured that someone will need one of the e-mails you delete somewhere down the line.
