- Search for lines beginning with a specific prefix in a specific file:

`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 [t]ermination character (space by default):

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

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

`look {{prefix}}`
