Each one of these commands will have specific examples added in time, for the moment there is just the basic description for a memory jogger :)

  • pwd - Gives you your current location in the directory hierarchy.
  • whoami - Tells you what user you are currently logged on as.
  • su - Become another user or super user once you have logged onto the UNIX system.
  • df -h - Check how much free disk space you have left.
