Linux – Useful Commandline Commands on Unix

commandcommand-line-interfacelinuxunix

As there is a windows version of this question, I decided to open a community wiki for the same question under unix, linux, and the like.

I'll be updating this list with the answers:

  • bash: exec 3<> /dev/tcp/localhost/80 # Redirect to port 80 of localhost
  • find: search for files in a directory hierarchy
  • htop: interactive process viewer, similar to top
  • xargs: build and execute command lines from standard input
  • tmux: detachable, re-attachable command line sessions
  • apropo: find relevant man pages
  • vmstat: See the state of your system

Websites:

  • commandlinefu.com
  • serverfault.com

Keyboard shortcuts:
– Ctrl T (BSD specific): send SIGINFO to a running program
– Magic SesRq key (Linux specific): en.wikipedia.org/wiki/Magic_SysRq_key
