Greetings,

I came across some odd behavior when using the print function and I was curious to see if someone could explain to me why it happened. In my script, I read in a file that contained lines with two strings connected with an equal sign (e.g. string1=string2).

As I read in each line, I chomped off the newline character at the end, split on the equal sign, and then created a hash where the key was the second string and the value was the first.

I would then loop through the hash like this:

foreach my $item (sort keys %hash){
   print "The $item is $hash{$item}\n";
}

I was expecting it to print:

The key is value

But what I got was:

is value

After pulling my hair out, I finally realized that the file I was reading in was created in Windows so each line ended with a carriage return. The chomp only removed the \n and left the \r. So each key had a \r at the end of it.

Once I removed the \r character it printed out just fine.

My question is why did the print function not print anything before the \r character?

Thanks!
