Perl To Executable
Perl can't find the Windows shell cmd.exe that is used under the hood to run the program passed to system. Use some utility as Process Monitor to see what's going on at the OS level. Share improve this answer. Pp can create an executable that includes perl and your script (and any module dependencies), but it will be specific to your architecture, so you couldn't run it on both Windows and linux for instance. From its doc: To make a stand-alone executable, suitable for running on a machine that doesn't have perl installed:% pp -o packed.exe source.pl # makes packed.exe # Now, deploy 'packed.exe. Is there a way to get an absolute path to the Perl executable for the current process? $^X will give me the Perl executable name, but the doc states that it will sometimes be a relative path, and this seems to be true on OS X for example. The first thing most programmers learn how to do in a new language is to instruct their computer to print a 'Hello, World' message to the screen.It's traditional. You'll learn to do something similar — but slightly more advanced — to show just how easy it is to get up and running with Perl.
Take your first steps into the fascinating world of Perl by setting up Perl on your computer and then writing your first script.

Check If Perl Is Installed
Before you download Perl, you should check to see if you already have it. Many applications use Perl in one form or another, so it may have been included when you installed an application. Macs ship with Perl installed. Linux probably has it installed. Windows doesn't install Perl by default.
It's easy enough to check. Just open a command prompt (in Windows, just type cmd in the run dialog and press Enter. If you're on a Mac or on Linux, open a terminal window).
and press Enter. If Perl is installed, you receive a message indicating its version.
If you get an error such as 'Bad command or file name,' you need to install Perl.
Download and Install Perl
If Perl is not already installed, download the installer and install it yourself.
Close the command prompt or terminal session. Go to the Perl download page and click on the Download ActivePerl link for your operating system.
Perl Executable Name
If you are on Windows, you may see a choice of ActivePerl and Strawberry Perl. If you're a beginner, choose ActivePerl. If you have experience with Perl, you may decide to go with Strawberry Perl. The versions are similar, so it's entirely up to you.
Follow the links to download the installer and then run it. Accept all the defaults and after a few minutes, Perl is installed. Check by opening up the command prompt/terminal session window and repeating the
command.
You should see a message indicating you have installed Perl correctly and are ready to write your first script.
Write and Run Your First Script
Perl Online Compiler For Windows
All you need to write Perl programs is a text editor. Notepad, TextEdit, Vi, Emacs, Textmate, Ultra Edit and many other text editors can handle the job.
Just make sure you're not using a word processor like Microsoft Word or OpenOffice Writer. Word processors store text along with special formatting codes that can confuse programming languages.
Write Your Script
Create a new text file and type the following exactly as shown:
CAUTION: If Device Guard or Credential Guard is enabled on a Windows 10 Creators Update 64-bit system, you must ensure that Microsoft KB4016251 is installed on the system before you install McAfee products. Mcafee livesafe from windows 10. Microsoft KB4016251 is included in Windows 10 Creators Update build 15063.11 or later.Because of an issue in Windows 10 Creators Update, if Microsoft KB4016251 is not installed and you install McAfee products, the system will show the following blue screen error and will no longer be bootable.
Save the file as hello.pl to a location of your choice. You don't have to use the .pl extension. In fact, you don't have to provide an extension at all, but it's good practice and helps you locate your Perl scripts easily later on.
Run Your Script
Back at the command prompt, change to the directory where you saved the Perl script. In DOS. you can use the cd command to move to the specified directory. For example:
Then type:
to run your script. If you typed everything exactly as shown, you are prompted to enter your name.
When you press the Enter key, Perl calls you by your name (in the example, it is Mark) and give you a dire warning.
Congratulations! You have installed Perl and written your first script.
