Generate regular expressions. More information: https://github.com/pemistahl/grex.

• Generate a simple regular expression:

grex {{space_separated_strings}}

• Generate a case-insensitive regular expression:

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}}

• Add {min, max} quantifier representation for repeating sub-strings:

grex {{[-r|--repetitions]}} {{space_separated_strings}}
