Is it possible to get a list of strings from a regex?












0















Is there a Linux command or software library that returns a list of strings matching a regex it is given as input?



For example, d would return 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.



Given that regexes are already quite power-consuming I'd be really suprised if this was the case. Still, if such a solution does not exist, what alternatives are there?

  • And a dot should return ALL characters except newline? No, such function does not exist.

    What about the output for .*? Infinite number of elements in an array?

  • Any regex or just a character class?

  • You could write one, but as pointed out, the answer may be infinite. You could write a generator in some languages and call it to produce as many matches as needed.
