Yes,

When you use the -p switch, it takes the input (from the stdin pipe) and processes it, line by line. So, a line will have no more than one "\n" in it.

See the documentation for the "-p" switch here: http://perldoc.perl.org/perlrun.html

What you may want to do is this:

perl -pe 'BEGIN {$/=undef} s/\n\n/foo/'

$/ is the Perl special variable for the end-of-line delimiter. Changing it to undef causes it to read the input in all at once.

Is there any reason the following shouldn't work?

...no I don't speak perl.

I'm doing this via, "filer thru command".
