not personally. i use sed - i figure it's called a stream editor for a
reason... the article seemed a bit odd in my mind and i've seen and
written a fair number of shell scripts.
the key to shell scripts is you need to remember they get built in
pieces. the overall thing might look utterly incomprehensible, but if
you break it down it will make sense. you read a shell script one way
and c a different way - just like you read a cookbook one way and a
novel another.

a here file:
cat << EOF
blah
my path is $PATH
moo
EOF
that's pretty much it.
now back to beating a perl script into submission. (t's actually three
scripts acting together over tcp/ip - three test windows and at least
two edit windows and i have an 800x600 monitor that only allows two
xterms per screen. AUGH!
