ahem, is perl really everything these days?
and how portable that is?
is awk completely disregarded as a usable tool?
awk '{ s = $0; while (match(s,"PATTERN")) { print substr(s, RSTART,
RLENGTH); s = substr(s, RSTART + RLENGTH); } }'
this gives me the same results are your perl string
(which is shorter of course, after all it's perl).
it also gives the same results are grep -o on
a debian system i have access to.
also awk uses, AFAIK, ERE, in which case
the greediness may be controlled.
