BASIC UNIX COMMANDS TO REMEMBER

The basic commands used in the Unix shell are:

  • cd (directoryname)(Changes directories to the one named. In Unix, you change directories one level at a time.)
  • cd .. (Changes back up to the previous directory)
  • pwd(Prints -- displays to the screen -- the "working" or current directory)
  • ls(Lists the contents of the current directory to the screen)
  • ls -l(Same as above, but it lists like the DOS DIR command with more information)
  • mkdir(Make a directory -- same as DOS "md")
  • rmdir(Remove a directory -- same as DOS "rd")
  • cat("Concatenate," or show a files contents to the screen -- same as DOS "type.")
  • cp(Copy -- same as DOS "copy")
  • mv(Rename or "move" a file -- same as DOS "ren")
  • rm(Remove or "delete" a file -- same as DOS "del")
  • logout(Terminates a Unix Shell session)
  • |more(When entered at the end of a command such as "cat" or ls -l", this displays a page of text, then stops and waits for you to issue the command to go on)
  • sz (In the Unix shell, "sends" to your computer -- via ZMODEM -- the file named)
  • sx(In the Unix shell, "sends" to your computer -- via XMODEM -- the file named)
  • rz(In the Unix shell, tells the remote computer to "receive" a file from your computer. You need to return to your own computer and tell it to "send" a specific file or group of files)
