Dear Unix gurus!!
I'm studying the sed utility to do some text
manipulation for source files.
Taking an example file called 'datafile' :

I want to delete the line starting with eastern, and
the next 2 lines (whatever they may be).
I tried this command in a script file:
scriptfile:
/eastern/d
$d
$d
..and gave the command:
sed -f scriptfile datafile
... but it does not work (because $d matches any
newline, not the next two after 'eastern' ) Any clues
how to do it?
Thanks
Deepak
