Why not go about the problem like this?
#!/usr/bin/perl
use strict;
use warnings;
open (fh1, "/path/to/file") or
die ("can't open /path/to/file: $!");
my $first = 0;
while (<fh1>) {
if ( $first > 1 ) {
my @initial_values = split / /, $_ ;
# process intial values here
$first++;
next;
} else {
# process subsequent values here
}
}
close (fh1);
That is:
* use a temp variable that you manage yourself
(this, in my opinion, is more readable anyway)
* use the $! variable in the die statement
(that way, if it fails, you know why it failed)
