look {{prefix}} {{path/to/file}}

  • Case-insensitively search only on alphanumeric characters:

look {{-f|--ignore-case}} {{-d|--alphanum}} {{prefix}} {{path/to/file}}

  • Specify a string termination character (space by default):

look {{-t|--terminate}} {{,}}

  • Search in /usr/share/dict/words (--ignore-case and --alphanum are assumed):

look {{prefix}}
