![]() This is the default Unix location for the perl interpreter, on Windows #!C:\Perl\bin\perl.exe or #!C:\strawberry\perl\bin\perl.exe (depending on whether ActivePerl or Strawberry Perl was installed) should be used instead. On Unix systems this tells the Operating System to execute this file with the program located at /usr/bin/perl. Let's take a look at this program line by line: #!/usr/bin/perl # Outputs Hello World to the screen. First, edit it and put the following shebang line at the top of the file: This involves two changes to the sample program. Usually, Perl programs are made executable on their own. You can run a Perl program by running perl itself, and telling the shell the name of the file: PERL PRINT FULLNote: You may have to specify the full path to your program unless you are running the command prompt in that directory. With Strawberry Perl, you'll have to execute a Perl program from the command line as shown below.įrom a Windows command-line interface, you can run the program thusly: If the screen flashes and you can't see the output you might have to execute the file from within the windows shell (ie. To run a Perl program with a modern version of ActivePerl installed, you simply click on it. Save the file as and you have a Perl program ready to run. If you don't understand this yet, don't worry This will be explained in more depth later. #!/usr/bin/perl use strict use warnings print "Hello World" Instead of compiling your program into bytecode, like in C or Pascal, and then executing it, you can simply copy your program's source code to a different computer (that has the Perl interpreter) and run it.įor our first example, run your favorite text editor, and type something like this: Perl is an interpreted language, which means you will always need the Perl interpreter which will compile and execute your program each time you run it. However, if for some reason you don't have perl, you can explore the options available to you at the main Perl download page, which will provide links to source and binaries. Most Unix-like operating systems will include Perl by default, and Linux Standard Base mandates that all compliant Linuxes ship with Perl installed. ActivePerl has a prebuilt package repository and is supported by a corporation, while Strawberry Perl includes a compiler ( gcc) so that perl modules can be installed "on the fly" and is community-supported. Both are downloadable as native Windows installers. PERL PRINT INSTALLThere are at least two easy ways to install Perl on Windows: the ActiveState distribution, and the Strawberry Perl distribution. This will display which version of Perl you have installed on your computer, if it is installed. ![]()
