Linux User Management: Managing User Files and Processes
Removing users, as well as files and directories owned by specific users, is a routine task for most Systems Administrators. In this lab, we will remove a user and their home directory from the system, then search for any other files or directories owned by them and transfer ownership of those to a new user. Then we will search for and kill any processes owned by that user as well.
Table of Contents
Search for Any Running Processes Owned by the test User. Kill the Process by the Process ID (PID)
$ ps U test $ kill < PID >
Search the System for All Files Owned by the test User, Then Change the Owner and Group to ec2-user on Any Files That Are outside of the Home Directory and the Mail Spool
$ find / -user test $ chown ec2-user:ec2-user /var/tmp/appconfig.sh $ chown ec2-user:ec2-user /tmp/list.txt
Remove the test User and Home Directory from the System
$ userdel -r test
Verify That the Home Directory and the Mail Spool Were Removed. Also Verify That There Are No Other Files Owned by the test User on the System
$ find / -user test
$ ls /home
$ ls /var/spool/mail
