I'm trying to get regular expression matching working on both bash v3 as well as v4.
The following works on v4 (under RHEL6), but not under bash 3.00.15 (under RHEL4): [[ "6Server" =~ ([0-9]+)(.*) ]] This works on 3.00.15, but not under RHEL6's bash (4.1.2): [[ "6Server" =~ '([0-9]+)(.*)' ]] The prior actually throws a syntax error, so I can't even code around the syntax based on evaluation of $BASH_VERSINFO. Any thoughts on how to do this in a portable way? Thanks, Ray
