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.
