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.
