Useful Linux CommandsI keep a textfile in my home directory that lists useful linux shell commands, including the exact arguements required. This has been a valuable memory aid. I've copied some of this file below (lines that begin with the pound character (#) are comments). Note: I have a short video of some commands in action here: Linux CLI tutorial 1
disclaimer: these commands were discovered through research and trial & error. Although they worked for me on my installation (RedHat Linux 8 and 9, and later Fedora and Gentoo), I can't vouch for them. Use your own discretion and read the man pages.
