Lwp-download from file

[eatr]

Realize this is trivial for most but I'm just getting back to Perl.

How do I call lwp-download (or any Perl command line option) from a file instead of the command line?

Thanks

Write a batch file (it basically is a list of command-line commands within one file that you double-click and run)

@echo off
lwp-download ???

The @echo off removes the command echo, take this example:

echo Hello World!
echo.
pause

With echoing on, it would look like this in command prompt:

C:\WINDOWS\system32>echo Hello World!
Hello World!

C:\WINDOWS\system32>echo.


C:\WINDOWS\system32>pause
Press any key to continue . . .

With @echo off

Hello World!

Press any key to continue . . .

Anyway, any command-line commands you would send through the prompt, you can put inside the batch file, just open Notepad, type some commands in (one per line) and save it as a .bat file.

Is it possible to call it from within a perl (.pl) file as part of a larger program?

You can use system() within Perl to send commands directly to the console of the system running the script.

system ("lwp-download ...");

# or if you wanted the output from the command,
# surround it in backticks ``
my $output = `lwp-download ...`;
