RE: [MacPerl] Changing a file (pseudo) in-place?

[Tim Endres <time@ice.com>]

This is addressed on page 332 of the new Camel book. If you provide
the "-i" switch with no extension, then you do not get a backup file and
do not have to do the unlink of the backup file. Since 'undef-ing' $^I is
supposed to turn off inplace editing, I suspect that  $^I = "";  would be
the equivalent of "-i", and thus the script might reduce to simply:

	$/ = "\012";
	$^I = "";
	while ( <> ) { s/\012/\015/g; print; }
