`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):
