[Help-bash] Bash script supporting complex options like GNU find

[Peng Yu]

Hi,

I currently use getopt to support -s --long like options in bash scripts.

https://github.com/karelzak/util-linux/blob/master/misc-utils/getopt-parse.bash

But this solution does not support complex expressions made of '-a'
'-o'  '!' '(' and ')' as in defined in GNU find.

Does anybody know a solution that can make a bash script support these
complex expressions?
