Hello World in Perl — ITLC Tutorials

Tutorial Difficulty Level

This is how you would display “Hello World” in Perl. It’s quite similar to Bash, but note the differences carefully!

Create a text file called hello_world.pl containing the following code:

#!/usr/bin/perl
#
# The traditional first program.

# Strict and warnings are recommended.
use strict;
use warnings;

# Print a message.
print "Hello, World!\n";

#!/usr/bin/perl

# The traditional first program.

# Strict and warnings are recommended.

use strict;

use warnings;

# Print a message.

print "Hello, World!\n";

Navigate to a directory where your hello_world.pl is located and make the file executable:

$ chmod +x hello_world.pl

1	$ chmod +x hello_world.pl

Now you are ready to execute your first perl script:

./hello_world.pl

1	./hello_world.pl
