Shell History#

history#

You can do:

history

To see the history of commands that you’ve run since the start of your shell session (there is a limit, so very old commands may not show up).

You can also easily repeat a command from your history by using the ! operator:

  • ! + the number next to a command in your history (e.g., !100) will rerun that command.

  • ! + a character (or several characters) will run the most recent command in your history that starts with the same characters. E.g., if you have ls -l in your history as the most recent command starting with the letter “l”, then doing !l will rerun that command.

Arrow keys#

You can scroll through your shell history using the arrow keys.

  • ↑ will scroll backwards through your history

  • ↓ will scroll forwards through your history

When you find a command you want to rerun, just hit Enter.
