That's funny, the following seems to suggest GNU sed is one of the few
seds that DOES support it (which make IT not worth considering,
GNU extensions that don't work everywhere are responsible for a great
deal of evil I've seen in the world).
yeah, those stupid, extensible, full-featured GNU tools. What were they
thinking of? Let's use crippled programs that we know will work across 48
different flavours of Unix. Or should we all be looking at POSIX
specifications while doing things at the shell?
If we assume we're on a Linux box then we can use all the GNU features we want,
with the caveat "uses GNU features, might not work on traditional Unices".
This is one of the big wins of Perl- that you'll have powerful behaviour
across different machines that have perl installed.
Just as some traditional Unices are embracing GNOME as the desktop, they
should consider embracing GNU shell programs as a standard also,
then they could concentrate on other things that they are hopefully
better at.
