Try this to replace the formfeeds:

Code:
sed 's/^L/^M/' file > newfile

To get the ^L type <Ctrl>-V and <Ctrl>-L, for the ^M type <Ctrl>-V and <Ctrl>-M.

Thank you Franklin52,

It worked great but i need it to replace only for LAST occurrence of Form-feed (its doing for ALL occurrences now)

I tried the below to achieve this but no use, Please advise

sed 's / \ (.* \) ^L/\1^M/' file >file1

There's an imperfection the first solution, it replaces the formfeeds with a CR instead of a linefeed. This should replace the last formfeed in a file with a linefeed, supposing it's on the last line (the command must be on 2 lines!):

Code:
sed '$ s/^L/\
/' file
