in reply to perl -pie "???"

here's my take, since you want -p and not -n

perl -pi -e '$_="" if $i++' file

Update: oops! wrote it backwards. Thanx TZapper for pointing it out.

perl -pi -e '$_="" unless $i++' file

He who asks will be a fool for five minutes, but he who doesn't ask will remain a fool for life.

    Chady, your one-liner deletes everything but the first line.
