Replace FF character with CRLF

Hi,

I have a need to replace a FF character (Form Feed) in a printer spool file with a CRLF (Carriage Return & Line Feed).

I previously replaced the FF character with a blank character using the TR command (e.g: tr '\014' ' '), but I now need to insert a blank line too.

Can anybody help please?

That did work, but not quite how I expected. I need another blank line. I'd therefore need something like ; tr '\014' '\012\012'

Obviously, I can't do that because there's a mismatch of number of characters.

Is there any other method of doing this? Is it possible using 'sed'?

Or sed:

CODE

sed 's/^L/\
\
/g' inputfile >outputfile

To enter the "^L" character in vi, use Ctrl-V Ctrl-L.

I tried many solutions which didnt give me the desired effect. I eventually went with the following;

CODE

tr '\014' '\012'

Seemed to work for me

Thanks to those who responded smile
