Domanda

I use my internet browser to display images/graphs I created with gnuplot. So for each picture I have a plot.gp file that contains gnuplot commands. My final goal is to open an editor with the file plot.gp when I click on the picture.

The only way I found to achieve this is to use cgi to run a bash scripts. But I'm not able to make an "hello word" code work... So here is what I did :

  • I installed on linux the packaged cgi-mapserver
  • I saved in the file hello.bash in /usr/lib/cgi-bin/ and gave it the correct permission (chmod 755 /usr/lib/cgi-bin/hello.bash).

But when I do firefox /usr/lib/cgi-bin/hello.bash my browser display the whole file instead of only "hello world!"

My file /usr/lib/cgi-bin/hello.bash :

#!/bin/bash

echo "Content-type: text/html"
echo ""
echo "<html><head><title>Welcome</title></head>"
echo "<body>"
echo "Hello world"
echo "</body></html>"

I'm sure I forget something very basic... but I can't figure what it is :-(

Soluzione

You should use your browser's file associations to use your editor for downloaded .gp files. It is a web server, not a browser, who uses cgi-scripts.

Browser cannot run the shell script and show it's output. You can store shell script's output in a temp HTML file and open it like thisL

bash /usr/lib/cgi-bin/hello.bash > /tmp/hello.html

And then open it in firefox:

firefox file:///tmp/hello.html

I know this is in reply to a very old help request. But makbe it will help someone.

Provided that your server supports cgi and you moved the hello.bash script to the directory of cgi-bin. And then changed permissions to at least 644 and and owner ship of root:users. It will run as posted.

Doing this in LAMPP, from the browser I enter http://localhost/cgi-bin/hello.bash and I can see "Hello world"
