You could do this in place but using the -n switch rather than -p. The difference is there is no implicit print with -n so you can decide to print which lines you want. Like this (on *nix)

$ cat myfile
1st line
2nd line
3rd line
$ perl -ni.bak -e 'next if /^2nd/; print;' myfile
$ cat myfile
1st line
3rd line
$ cat myfile.bak
1st line
2nd line
3rd line
$

I hope this is of use.
