I've got a batch script that does some processing and calls some perl scripts.
My question is if there was a way to put the perl code directly into the batch script and have it run both types of scripts.
Active Perl has been doing this for years!
Below is a skeleton. You can only call perl once though. Because passing it the -x
switch says that you'll find the perl code embedded in this file, and perl reads down the file until it finds a perl shebang (#!...perl
) and starts executing there. Perl will ignore everything past the __END__
and because you told DOS to goto endofperl
it won't bother with anything until it gets to the label.
@rem = '--*-Perl-*--
@echo off
perl -x -S %0 %*
goto endofperl
@rem -- BEGIN PERL -- ';
#!d:/Perl/bin/perl.exe -w
#line 10
use strict;
__END__
:endofperl
Yes you can.
In fact this is exactly what the pl2bat
tool does: it transforms a perl program into a batch file which embeds the perl program. Have a look to pl2bat.bat itself.
So you can take the .pl
, convert it with pl2bat
, and then tweak the batch part as you need. The biggest part of the batch code must be put at the end of the file (near the :end_of_perl
label) because in the code at the top you are limited to not using single quotes.
However:
So I suggest instead to write the whole process in one Perl program.
Update: if you have one script and some Perl modules that you want to combine in a single batch file, you can combine the Perl file using fatpack
, and then apply pl2bat
on the result.
