Abstract
Here are some valuable tips to help you find important system files in RHEL 5, which get deleted by accident. Everything seems fine when your Linux machine works just the way you want it to. But that feeling changes dramatically when your machine starts creating problems that you find really difficult to sort out. Not everyone can troubleshoot a Linux machine efficiently but you can, if you are ready to stay with us for the next few minutes. Let’s look at what to do when some of your important system files are deleted or corrupted under Red Hat Enterprise Linux 5. The action begins now! Scene 1: /etc/passwd is deleted This is an important file in Linux as it contains information about user accounts and passwords. If it’s missing in your system and you try to log in to a user account, you get an error message stating Log-in incorrect and after restarting the system.
