Perl (Scripting) - return a string

Updated:   |  Perl (Scripting) articles

If you are not familiar with subroutines, check out our article on Perl - Getting Started with Subroutines.

Let's say you have the following script. In this example, the greeting subroutine will return string "Hello World".

sub greeting {
  return "Hello World";


Outside of the subroutine, the output of the greeting subroutine is stored in the $foo variable.

my $foo = greeting();


You could then print the $foo variable.

print "$foo \n";


Which would return the following.

Hello World


Likewise, you could store the output of the greeting subroutine in an array.
