Re: split file and put contents in variables?

[choroba]

Don't use print if the file can't be opened. Skip the whole program or the reading loop.

open my $test, '<', 'test.txt' or die "Can't open file: $!";
while (my $line = <$test>) {
    # chomp not needed with split on ' '.
    my ($pattern, $cyclo, $group) = split ' ', $line, 4;
    print $line if 'FOLDING' eq $pattern
                && 'SHAPE'   eq $cyclo
                && 'OXYGEN'  eq $group;
    }
}
