I meant

#!/usr/bin/perl
my $file = @ARGV[0];
if ( $ARGV > 0 ) { die "Usage: Lines.pl filename

my $lines = `wc -l $file`;
print "$file has $lines  
";

if ($#ARGV < 0) {
  die "Usage : q4.pl filename

}
my $file = $ARGV[0];
my $lines = `wc -l $file`;
my ($line,$rest) = split(//,$lines);

print "$file has $line lines
