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. - -- Life is short - so eat dessert first!
