Excellent Utilities: McFly – navigate through your shell history

Other Features

When suggesting a command, McFly takes into account the following factors:

  • The directory where you ran the command. McFly uses the PWD environment variable to determine directory.
  • What commands you typed before the command (e.g., the command’s execution context).
  • The frequency the command is run.
  • The time when the command was last run.
  • Has the command been selected in McFly before?
  • How often you run the command.
  • The command’s historical exit status.

McFly also offers the following functionality:

  • Augments your shell history to track command exit status, timestamp, and execution directory in a SQLite 3 database.
  • Highlights search string in a case-insensitive way.
  • Includes a simple action to scrub any history item from the McFly database and your shell history files. Press F2 and you can delete the selected command from the history.
  • Designed to be extensible for other shells in the future.
  • Replace the default theme with a light mode. It’s useful if you prefer a terminal with a light background.
  • Detect when directories are moved or renamed and updates the history.
  • Generate a training set with the command ‘mcfly train’.
  • Unicode support throughout.
