PHP is likely the easiest.
Just make a file script.php that contains <?php shell_exec("yourscript.sh"); ?> and send anybody who clicks the button to that destination. You can return the user to the original page with header:
<?php
shell_exec("yourscript.sh");
header('Location: http://www.website.com/page?success=true');
?>
This is really just an expansion of BBB's answer which lead to to get my experiment working.
This script will simply create a file /tmp/testfile when you click on the button that says "Open Script".
This requires 3 files.
The File Tree:
root@test:/var/www/html# tree testscript/
testscript/
+-- index.html
+-- testexec.php
+-- test.sh
1. The main WebPage:
root@test:/var/www/html# cat testscript/index.html
<form action="/testscript/testexec.php">
<input type="submit" value="Open Script">
</form>
2. The PHP Page that runs the script and redirects back to the main page:
root@test:/var/www/html# cat testscript/testexec.php
<?php
shell_exec("/var/www/html/testscript/test.sh");
header('Location: http://192.168.1.222/testscript/index.html?success=true');
?>
3. The Script :
root@test:/var/www/html# cat testscript/test.sh
#!/bin/bash
touch /tmp/testfile
This is how it look like in pure bash
cat /usr/lib/cgi-bin/index.cgi
#!/bin/bash
echo Content-type: text/html
echo ""
## make POST and GET stings
## as bash variables available
if [ ! -z $CONTENT_LENGTH ] && [ "$CONTENT_LENGTH" -gt 0 ] && [ $CONTENT_TYPE != "multipart/form-data" ]; then
read -n $CONTENT_LENGTH POST_STRING <&0
eval `echo "${POST_STRING//;}"|tr '&' ';'`
fi
eval `echo "${QUERY_STRING//;}"|tr '&' ';'`
echo "<!DOCTYPE html>"
echo "<html>"
echo "<head>"
echo "</head>"
if [[ "$vote" = "a" ]];then
echo "you pressed A"
sudo /usr/local/bin/run_a.sh
elif [[ "$vote" = "b" ]];then
echo "you pressed B"
sudo /usr/local/bin/run_b.sh
fi
echo "<body>"
echo "<div id=\"content-container\">"
echo "<div id=\"content-container-center\">"
echo "<form id=\"choice\" name='form' method=\"POST\" action=\"/\">"
echo "<button id=\"a\" type=\"submit\" name=\"vote\" class=\"a\" value=\"a\">A</button>"
echo "<button id=\"b\" type=\"submit\" name=\"vote\" class=\"b\" value=\"b\">B</button>"
echo "</form>"
echo "<div id=\"tip\">"
echo "</div>"
echo "</div>"
echo "</div>"
echo "</div>"
echo "</body>"
echo "</html>"
