PERL on windows accessing variables from a config file
Folks,
I'm a perl moron, so please speak very slowly. : )
I'm modifying a build script that starts up an apache server. Now there is a .config file that hardcodes an old webserver path like this c:\oldWebserver. Now I don't want that hardcoded value, rather wish to use an environmental variable and from a .cmd file can access it with this syntax %APACHE_HOME%.
However, I need to be able to retrieve this value inside this .config file and the same syntax doesn't working.
I also tried:
%{APACHE_HOME}
$ENV{APACHE_HOME}
to no avail.
Any thoughts or recommendations?
Thanks!

How are you using this .config file? Usually .config is for shells, which Windows doesn't usually have.

I'm passing in the config file as a param when starting apache.
Like this
%server_dir%\bin\httpsd.exe -e debug -w -f "conf\inputs.conf" -d "."

The env variable may not be what you expect, try this code I found here:
Code:
#!/usr/bin/perl

print "Content-type:text/html\n\n";
print <<EndOfHTML;
<html><head><title>Print Environment</title></head>
<body>
EndOfHTML

foreach $key (sort(keys %ENV)) {
    print "$key = $ENV{$key}<br>\n";
}

print "</body></html>";
