|
|
|
`grex {{space_separated_strings}}`
|
|
|
|
- Generate a case-insensitive `regex`:
|
|
|
|
`grex {{[-i|--ignore-case]}} {{space_separated_strings}}`
|
|
|
|
- Replace digits with '\d':
|
|
|
|
`grex {{[-d|--digits]}} {{space_separated_strings}}`
|
|
|
|
- Replace Unicode word character with '\w':
|
|
|
|
`grex {{[-w|--words]}} {{space_separated_strings}}`
|
|
|
|
- Replace spaces with '\s':
|
|
|
|
`grex {{[-s|--spaces]}} {{space_separated_strings}}`
|
|
|
|
