But launching > perl seems a bit of overkill when I just have to do a simple match in a >.bashrc script or when I need a small shell script wrapper. Looking at the man page for everything in /bin that matches the pattern *.exe find the following that may be of interest. Testing to see if these actually work is left as an exercise for the OP. :-) pcregrep - a grep with Perl-compatible regular expressions. grep, egrep, fgrep - print lines matching a pattern -w, --word-regexp Select only those lines containing matches that form whole words. The test is that the matching substring must either be at the beginning of the line, or preceded by a non-word constituent character. Similarly, it must be either at the end of the line or followed by a non-word constituent character. Word-constituent characters are letters, digits, and the underscore. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
