Run Program from Bash CGI-Script
Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!

1. The problem statement, all variables and given/known data:
This is a problem I am having with my 2 semester senior project. I have a LAMP server running Ubuntu 9.10 with gnome that I need to run a program on from a button on its website. I'm using 'xterm -e vlc'. A member cero pointed out that I needed to include the display name which is ':0.0', I got when I ran 'echo $DISPLAY' in the terminal. I can run 'xterm -e vlc' in a terminal and 'xterm -display :0.0 -e vlc' in a terminal. However, it doesn't work in a bash cgi script.

I also tried adding localhost before ':0.0' to see if that works, but it didn't.

In short words, I need a program to run on the server from a button on the website. Nothing from the cgi-scrip needs to be displayed on the website.

The website is: Crimson Security - Home if you want to check it out.


2. Relevant commands, code, scripts, algorithms:
xterm -display :0.0 -e vlc
xterm -e vlc
xterm -display localhost:0.0 -e vlc


3. The attempts at a solution (include all code and scripts):
Code:
#!/bin/bash
echo "Content-type: text/html"
echo ""

xterm -e vlc

echo "<html><head><title>Crimson Security - Redirect"
echo "</title></head><body>"

echo "<h1>You have started VLC Media Player</h1>"
echo "Today is $(date)"
echo "<br><br>"
echo "<A HREF='javascript:history.go(-1)'>Go Back</a>"

echo "</body></html>"

Also tried:
Code:
#!/bin/bash
echo "Content-type: text/html"
echo ""

#main line of code that I need to work
xterm -display localhost:0.0 -e vlc
#####################

echo "<html><head><title>Crimson Security - Redirect"
echo "</title></head><body>"
echo "<h1>You have started VLC Media Player</h1>"
echo "Today is $(date)"
echo "<br><br>"
echo "<A HREF='javascript:history.go(-1)'>Go Back</a>"

echo "</body></html>"

4. Complete Name of School (University), City (State), Country, Name of Professor, and Course Number (Link to Course):
The University of Alabama; Tuscloosa, AL; Dr. Kenneth Ricks; ECE 494 Capstone Design -- The University of Alabama

Note: Without school/professor/course information, you will be banned if you post here! You must complete the entire template (not just parts of it).

Edit: If I forgot something, please let me know.
