Tip of the Week: Time Saving Terminal Tips

This will help you save time while using the BASH terminal - submitted by Carlos Peraza


There are a couple of tricks you can use to save time in a BASH terminal, by making use of BASH's history, silently stored in the file ~/.bash_history. These work in all BASH terminals, including Konsole, XTerm and gnome-terminal.


Here are a couple of Tips:

  • If you press the up, or down arrow, then BASH will cycle through the list of recently used commands
  • If you type part of a command, and then press <tab>, BASH will finish the command name for you. If there is more then one command, all of them are displayed on pressing <tab> again (see Command 2 in screenshot)
  • If you type part of a filename, and then press <tab>, then BASH will finish the filename for you. Again, if there is more than one option, all are diplayed on pressing <tab> again (see Command 3 in screenshot)
  • Press ctrl-R. A search box comes up for you to find previous commands
  •  ! commands - This will search the History and execute a command. The command will be displayed before execution (See Commands 4-6). There are 5 ways you can use the ! in BASH
  1.  !! - Execute The Last Command
  2.  !x - Execute The Last Command Starting with x
  3.  !-n - Execute The nth from last Command
  4.  !?abc - Execute The last Command that contained abc
  5.  !n - Execute The nth Command in history (not very useful)
  • If you press alt-. then the last parameter you passed to any command will appear at the cursor. See Command 8. I presses alt-. once, and myfile1 came up. I pressed it twice and myfile2 came up, etc...
  • ctrl-U and ctrl-K 'cut' from the cursor to the beginning and the end of the line respectively. This can later be pasted using ctrl-Y
