You can find such a routine in delete routine in db.pl or db_utils.pl of Links2.0.

Hope this helps...

Then try the following:
-make an array, by splitting by \n
-shift that array
-print that array to file

...and you're ready!

Or check out subscribe.cgi for a delete routine without an ID.

How bout:

open (IN, "<input.txt") or die $!;
open (OUT, ">output.txt") or die $!;
$junk = <IN>;
while (<IN> ) {
print OUT;
}
close IN;
close OUT;

you now have a copy of the input file in the output minus the first line. Do a rename() to overwrite the file.

Cheers,

Alex
