There are as many different regex flavours as there are Linux distros.
Each follows the basic rules but implements them slightly differently
and adds their own 'extensions'.

The best place to pose a regex question is in the sphere of usage, i.e.
Perl regexes differ hugely in implementation from OO langs like Python
or Java, while shells like bash or zsh use regexes slightly differently,
as do shell scripting languages like awk or sed.

If you care to PM me with details of the language/context I will try to
help but I am no expert.
