This summary provides the high-level information about basic file commands and networking commands: Basic file commands include cat, more, head, tail, diff, sort, uniq, wc to display, compare, and analyze file contents. Networking commands allow connecting to remote systems like telnet, ftp, ssh and checking processes with ps, prstat. Shell commands set environment and launch jobs in foreground/background.
