M=E1rio,
I'll try to save you some time here. The script below should do exactl=
y
what you asked for help with. However, as you can see, sed is a
``write only'' language. If you're going to be maintaining this code, =
I
would suggest rewriting it in something a bit more readable such as awk=
,
or perl.
-------- START OF FILE --------

If you want to fit the script on one line, replace the line feeds with =
semicolons (``;'').

P.S. I would advise against making a habit of using ``$'' or any other
character that has special meanings in regular expressions as a
substitution delimiter, unless you enjoy driving yourself crazy when th=
ings
don't work the way you expect them to.
