Re: Bash regular expressions

In bash 3.2, the [[ ]] quoting rules changed slightly.  Since [[ already
introduces special quoting rules, single quotes are not required; the
regex is already protected by the shell from globbing.  Try this instead:

[[ abc =~ a.*c ]] && echo It works

And since none of this is cygwin specific, you should report this upstream
to bug-bash AT gnu DOT org if you think it is a bug.
