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.
