How to make a simple perl script

Hello, In this tutorial I will show you how to make a simple perl script that says "Hello World!" on your screen.

Step 1: Open Notepad or Notepad++ on your computer.

Step 2: Write this on the first line:

Code:

#!/usr/bin/perl -w

The Purpose of this is to tell the system that it is a perl script.

Step 3: Press Enter 2 times and write this:

Code:

print "Hello World!\n";

Print is one of the most commonly used functions in perl. It tells Perl to display what is in the quotes on your screen. Remember not to capitalize print or else it wont work. The \n tells perl to begin a new blank line on the screen after the text.\

Step 4: Write this on the next line:

Code:

sleep 2;

Basically what this does is tell perl to pause for 2 seconds or you can replace the 2 with any number you want. It just gives you time to read it, if you dont add this the script will just quickly open and close in under a second.

Step 5: Write this on the next line:

Code:

exit;

As you probably guessed this tells perl to close the script. Now for this script it is not necessary because after it stops pausing and there is no more coding it will just close.

When you are done it should look something like this.

Code:

#!/usr/bin/perl -w

print "Hello World!\n";
sleep 2;
exit;

If you want to learn how to script in perl then you shouldn't just copy the script right there ↑. The purpose for this tutorial is for you to learn.

Thanks for reading.
