run bash script from web interface

[b-boy]

Hi guys I have apache2 installed and I want to run a few bash commands. I hvae tried a few examples but it does not work for me.

so here is the tutorial i followed http://www.yolinux.com/TUTORIALS/LinuxTutorialCgiShellScript.html

but basically here is the code in this file /var/www/cgi-bin/cat-a-text-page

#!/bin/sh
CAT=/bin/cat
COLCRT=/usr/bin/colcrt

echo Content-type: text/plain
echo ""

if [[ -x $CAT && -x $COLCRT ]]
then
$CAT $1 | $COLCRT
else
echo Cannot find command on this system.
fi

and on my index.html

<A HREF="/cgi-bin/cat-a-text-page?/home/user1/public_html/text-file.txt">Text of link</A>

all that happens when iclik on the link is it shows the bash script and not the output of the script.


Just a note the cgi-bin dir I created by my-self as it was not there and the part in the html code that is bold does not exist

for stuff like that to work you need apache with cgi enabled (it's probably a module, don't know if it's included by default), and your apache config will/must indicate where the cgi-bin directory is located (probably with something like 'ScriptAlias' or so).

If you get just the contents of the scipt, that's an indication that the script is not executed, and the above is the first thing to check.

Also, the script expects a parameter ($1). You simply used the sample URL from the tut, with a sample filename that doesn't exist on your system (!?)

If you want a web app (or script) to display the contents of a file, you better tell it which file, make sure that file exists, and has a content to show.
But that is probably just problem no. 2. First check that you actually have cgi, and where the real cgi-bin directory is located
