But sed works on each line of input, so you need to address only the first line: $ cat myfile | sed "1s/^/\n\n/" For sed on Solaris 9, this will work: $ cat myfile | sed '1s/^/\ > \ > /' Note the single quotes to avoid escaping by the shell. The double-quote version: $ cat myfile | sed "1s/^/\\ > \\ > /" And in perl: $ perl -pe "BEGIN {$/ = undef;} s/^/\n\n/;" myfile I'm sure there are other ways, including using awk, etc. -David
