[TxMt] help with perl search/replace

[Brad Choate]

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.
