was suggested (the suggestion used symbolic name instead of a number and
didn't use word boundary). Seems like word boundary is needed, but I
couldn't get this to work. Are the regex boundary matchers not
supported by bash =~ operator?
I don't think bash equivalent of test implements Perl RE.
Neither the base test implementation, to that extent.
I thought, perhaps incorrectly, that \b has been around forever and is
posix.
In any event, looks like
[[ $(id -G) =~ (^| )544($| ) ]]
would work.
