How to stop a Perl program from closing its window when it is finished?

Question

How can I stop my Perl program from closing the window after finishing execution in windows?

I can run a Hello World Program, but it closes way too quick for me to actually read it.

print "Hello World\n";
while (1){sleep(1)}

Seems to be the only solution I could find, but I'm betting there is a better way to do this.

Solution 1

Run your script from the Windows command prompt, instead of clicking on an icon in Explorer. When you run console mode programs from clicking on an icon, Windows will open a window for the program, run it, then close the window. When you run console mode programs from a command prompt, the window won't close:

C:\test> perl hello.pl
Hello World

C:\test>

Solution 2

print "Hello, world\n";
print "Press RETURN to continue ";
<STDIN>;

Solution 3

Add this line to the end of your program:

system("pause");

Windows will prompt with "Press any key to continue . . ."

How are you executing your program? Are you not doing it directly from a command line?
