Show HN: unix-shell-script-kit v12 = many utility functions for your scripting

Unix shell script kit v12 adds new random character functions, motivated by the recent Hacker News post about shell random generation.

The new functions use /dev/urandom, are POSIX compatible, and provide various character class helpers to generate :alpha:, :digit:, :graph:, etc., and with a length parameter.

Example:

     random_char 'ABCD' 8 => DACABBCA
