Re: How to avoid this greedy match?

I'm not sure how it works, but I think <> or \<\> is a RegEx reserved
character for word matching.

That only works for other regular expression engines in programs like vi/less/grep etc.

$ echo "abcdefg cde lmncdeopq" | grep -o -e 'cde'
cde
cde
cde
$ echo "abcdefg cde lmncdeopq" | grep -o -e '\<cde\>'
cde


I seem to remember that Jeffrey Friedl's[1] book describes a way to emulate left and right word boundaries in Perl's regular expressions.
