Thanks,
I had been digging through the sed manpages and a couple online sed users
guides: a lot more droll and pedantic.
That does exactly what I wanted to do. Thanks again:-)

Hi,
Yes sed is very powerful and can use regexps. This page is awesome, I refer to
it for almost all of my sed needs:
http://www-h.eng.cam.ac.uk/help/tpl/unix/sed.html
Funny thing is, the thing you need, double spacing is the first thing in the
list.
sed G yourfile.txt > doublespaced.txt
Note the page just shows you the sed line, you have to know how to redirect to
a file etc. if you just do:
sed G yourfile.txt
it will display the file with double spacing, not actually write the file with
the double spaces, so that's why the > and the new file name. If you try to
write it to the same file it will erase everything in the file which is
probably not a good thing lol.

Salutations,
does anyone here have experience using sed, the command-line stream editor?
Can sed use regular expressions in the replacement-string? I'm wading through
the documentation, but I'm having trouble digesting it all (it's very robust,
which is good once you master it, but adds to the initial learning curve).
I can find lots of applications to search for regular expressions, but I
still can't find anything to use regular expressions in the substitution field.
I want to run through a text file and find every carriage-return (designated
"$" IN MOST PROGRAMS) and substitute it with two carriage-returns (in
openoffice, the only place I can do this right now, it has to be "\n\n").
Before I commit myself to learning sed, I wanted to double-check it can do
what I want it to.
thank you:-)
