Open a command prompt, type the following:

perl -le "print $^X"
[download]

Copy the output from above (e.g. the output for me was D:\perl\bin\perl.exe), run the following from the command prompt (remember to change my example path for the output of the first command):

assoc .pl=PerlScript
ftype PerlScript=D:\perl\bin\perl.exe "%1" %*
[download]

test.pl will now run the script rather than open it in your text editor.

1)Perl is normally not installed in ms Os. that's incredible but is true. you'll need a distro of Perl for your os: consider as better choice (in my opinion) Strawberry Perl or even activeperl

2)then you have to verify the default association of program in your system: if you have a 'HelloWorld.pl' and when you open it pop-up a text editor it means that the default program id that text editor.

3)if you have Perl installed you must to be able to launch the command 'perl -V' at bottom of the output you'll find wher your Perl is..

4)if you have Perl installed but not associated as default for '.pl' files you are able to run 'perl c:\path\to\yourhelloworld.pl'

You could try running:

perl test.pl

Thank you, but it says it's not a recognizable file :(

That perl isn't a recognizable file? Or test.pl isn't?

If the former, are you sure that you've installed Perl correctly?

use Moops; class Cow :rw { has name => (default => 'Ermintrude') }; say Cow->new->name

I might be mistaken on that, but I think you can only have Windows open files from the terminal with the default application. That is, the same one that will open by double clicking your file. So if you change it on one context, the other will follow.

If you don't want the default behaviour to be "run perl" for every .pl file, you could always give your test file another extension, like .ple. Or there's the solution of creating a batch file to start your script.

Thank you, I saved it at test.sh and now a pop up appears asking me to choose the correct program to open the file.

Thank you for the awesome articles!

I have no problems running Perl programs in the browser, but I want to learn how to run them in the CMD because that way I could write desktop programs and that will be cool.

Every time I run the commands with perl in the CMD I get the - "'perl' is not recognized as an internal or externalcommand,operable program or batch file."

For clarity, are you still unable to run perl from the command prompt? If so ensure that the path to perl is in your PATH variable:

• Right click 'My computer'
• Select 'Properties' from the drop down list
• Select 'Advanced'/'Advanced system settings' (depending on OS version)
• Click 'Environment Variables
• Add the path to perl.exe in 'System Variables'->'Path'. If you don't know what this path should be search for perl.exe on your system.
• Open a new command prompt, type perl -v

Thank you, I did what you told me, I added Perl to the ENV variables like this:

 C:\Program Files (x86)\PC Connectivity Solution\;C:\Program Files (x8
+6)\AMD APP\bin\x86_64;C:\Program Files (x86)\AMD APP\bin;C:\xampp\php
+\zend_framework\bin;C:\Program Files (x86)\Lua\5.1;C:\Program Files (
+x86)\Lua\5.1\clibs;C:\xampp\php;C:\ProgramData\Composer\bin;C:\Progra
+m Files\TortoiseSVN\bin;c:\Program Files (x86)\Microsoft SQL Server\1
+10\Tools\Binn\;c:\Program Files\Microsoft SQL Server\110\Tools\Binn\;
+c:\Program Files\Microsoft SQL Server\110\DTS\Binn\;C:\xampp\perl\bin
+\perl.exe
[download]

And when I run  perl -v in the CMD like this:

C:\Users\Stefany>perl -v
[download]

I get this error -

'perl' is not recognized as an internal or external command,
operable program or batch file.

Please help!

1. Right click 'My computer'
2. Select 'Properties' from the drop down list.
3. Select 'Advanced'/'Advanced system settings' (depending on OS version)
4. Click 'Environment Variables.
5. Add the path of perl.exe in 'System Variables'->'Path'.
6. open cmd promt
7. cd <your_path_where_perl_path_is_saved>
8. In case your perl file is saved in D drive then, the type D: in cmd promt
9. run the command perl <perl_file_name>

Okay, step one ... do you know that Perl is installed on your system and working?   If so, which one (Strawberry, ActiveState, etc.) is it?   How do you know?

If you open CMD, and type the word perl -V, with a capital-V, exactly what does or does not happen?

In (I think ...) the System control-panel, is there presently a file-association for .pl?   Right now it would seem that there is not one, and Windows is guessing that it is just text to be edited, but it might also be that .pl is right now associated with Sublime Edit.   If you right-click, are you given a choice for “Open With ...” ??

#!/usr/bin/perl
use strict;
use warnings;

use Path::Tiny;
use autodie; # die if problem reading or writing a file

my $dir = path("/tmp"); # /tmp

my $file = $dir->child("file.txt"); # /tmp/file.txt

# Get a file_handle (IO::File object) you can write to
# with a UTF-8 encoding layer
my $file_handle = $file->openw_utf8();

my @list = ('a', 'list', 'of', 'lines');

foreach my $line ( @list ) {
    # Add the line to the file
    $file_handle->print($line . "\n");
