Is it possible to run a batch file as a cgi in apache under windows?
Question
This sounds incredibly simple to do, but I can't make it work. I have it working with awk and perl, but cmd.exe wasn't designed to be a cgi program so no matter what I do, I either get the browser downloading the file, internal server error, or I get the path of the current directory as the first line.
You HAVE to put a #! in the first line of a cgi, or you get an internal server error, but I end up with
C:\Program Files (x86)\Apache Software Foundation\Apache2.2\cgi-bin>#!c:\windows\system32\cmd.exe /c
Content-Type: text/html
<HTML><BODY>
<PRE>Your environment variables are:
</PRE></BODY></HTML>
I've tried with /c, without, any number of permutations, it always prints the current working directory first before anything, so I can't print out the content type as a header.
Anybody ever get this working? I see lots of speculation in the results google shows me, but no actual working examples.

First check Apache mine.types, comment out this line .
#application/x-msdownload exe dll com bat msito
application/x-msdownload exe dll com bat msiThis line means : Apache treat
.exe,.dll,.com,.batand.msifile as download file instead of executing it. So if you want to run.batfile in cgi , you need to comment it out.(I guess you have already done that, just in case somebody new doesn't know.)#AddHandler cgi-script .cgi .bat .extAs I tried, if you left this above line commented out, it will not influence.I'm using Apache 2.2 server of Zend . So just leave it alone.
Write your bat file
#!c:\\windows\\system32\\cmd.exe /cThis kind of shell-like comment is not working , at the first line of
.bator.cmdfile, you need to write :@echo off echo Content-type: text/plain echo.The last line means output a new line , if you didn't do that, you will get "Premature end of script headers: xxx.bat " 500 HTTP error.
echo ^<html^>"^" is escape character for cmd.
echo ....The reason why your
.batnot working is because that you did not stick to the HTTP protocol.Put your
.bat/.cmd/.exefile into cgi-bin directory.Now , check it out.
Advise : read the HTTP protocol.
Other issues:
If you invoke other
.exein your cgi bat file such as curl.exe ,it will not work as expected,I don't know why , any information will be thanks.- Refers: http://www.jlk.net/apache/debugging_cgi.shtml

I'm not 100% clear on the method you are using right now, but...
I don't think you can treat exe files (ie, cmd.exe) as a CGI binary (eg, AddHandler cgi-script .exe ), nor run .bat files directly.
If you want to execute a batch file via Apache (and display the output on the page), the simplest way to do this is to execute that batch file by running a PHP script that uses exec(path to bat file) to execute the command line operation and echo its output.
Aside from doing this in your Browser via a URL, you can also do this from the command line by using wget/curl, or you can bypass Apache and run the PHP interpreter directly.
And I'm sure you can also do something similar to exec() via perl.
