|
|
- 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 termination character (space by default):
|
|
|
|
`look {{[-t|--terminate]}} {{,}}`
|
|
|
|
- Search in `/usr/share/dict/words` (`--alphanum` and `--ignore-case` are assumed):
|
|
|
|
`look {{prefix}}`
