deleting (i.e) not printing lines Here are the examples for not printing the 4th line:

sed: sed -n '4!p'

awk: awk 'NR != 4'

perl: perl -ne '$. != 4 && print'

Not much between them really.

I would consider 'sed 4d' to be significantly easier than doing the same in Perl, but I don't disagree that it's not that hard to do in either.
