I can think of two ways:
if your system implements truncate you can say:
open IN, $file or die "$file:$!";
$temp = <IN>; # don't throw away first line;
print <IN>; # print the rest of the file.
truncate IN, length($temp); # only keep the first length($temp) bytes
or the more portable:
open IN, $file or die "$file:$!";
$temp = <IN>; # don't throw away first line;
print <IN>; # print the rest of the file.
close IN; # get rid of the filehandle
open OUT, "> $file" or die "$file:$!"; # replace file
print OUT $temp; # stick first line back in
close OUT; # flush the file
