Re: Must have CLI of Perl's sed's n command

Your formatting is kind of terrible, but you can check $. and skip if the first line (next if $. == 1). Another option might be to use the trick of using -M and a version to get something to run before the magical while wrapping the -n does. Use something like -M5.010’;scalar <>;’ to have the first line read (and discarded).

> Your formatting is kind of terrible, yep, that's one way to express it. > skip if the first line `(next if $. == 1)` If that's the goal (???) `$.-1` is false for the first line only, he could `&&` it with the flip-flop's start condition.

seems we to conclude there's none, as next if $_ == ... is different; costlier & less eff. - i got/knew it in first place	[reply]

$_ and $. are not the same thing. Could you show the sed example you're trying to mimic? I'm not sure I understand. `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l]
