I need a file with ls -la /dev from a Red Hat Enterprise. Please someone would send me rhelserver@gmail.com

Thanks in advance

This command simply lists the entire contents of the /dev directory, including hidden items. But this folder does not contain any files, just special "files" to access devices on the system. So no one can send you a file like there, but you certainly can create one in there if you are missing one.

What is it that you are trying to do or are missing?
