Bash uses ERE (Extended Regular Expressions) here. There is no \< or \> in an ERE. http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap09.html#tag_09_04 > This evaluates as false: > > [[ 'foo bar' =~ \<foo\> ]] Well, of course it does, because \< is just a literal less-than sign in a POSIX ERE. wooledg:~$ re='\<foo\>' wooledg:~$ [[ '<foo>' =~ $re ]] && echo yes yes You might as well remove the backslashes, because they serve no purpose here. If you thought they meant "word boundary" or something, you're in the wrong language.
