Perl (Scripting) - Sum of integers in a file

Updated:   |  Perl (Scripting) articles

Let's say file1.txt contains integers.



The following markup will get the sum of the integers in file1.txt. Running this will script will produce 30.4, which is the sum.

my $file = "/path/to/file.txt";
open(FH, "<", $file) or die "cannot open $file $! \n";

my $sum = 0;
while (my $line = <FH>) {
  $sum += $line;

close FH;

print "$sum\n";
