I want to launch a bash script when a button is pressed on a website. This is my first attempt:
<button type="button" onclick="/path/to/name.sh">Click Me!</button>
But no luck. Any suggestions?

4are you trying to run the script on the user's machine or on the server?– MatCommented Jun 4, 2011 at 9:05

As stated by Luke you need to use a server side language, like php. This is a really simple php example:
<?php
if ($_GET['run']) {
# This code will run if ?run=true is set.
exec("/path/to/name.sh");
}
?>
<!-- This link will add ?run=true to your URL, myfilename.php?run=true -->
<a href="?run=true">Click Me!</a>
Save this as myfilename.php and place it on a machine with a web server with php installed. The same thing can be accomplished with asp, java, ruby, python, ...

4This answer works on my Ubuntu desktop with apache2 and php5 installed. Following is some additional information to help better understand this answer: 1. "myfilename.php" may be placed under the web server's root directory (DocumentRoot) which usually is "/var/www". 2. "myfilename.php" contains the above code, plus other HTML code. 3. The web client uses "<server name>/myfilename.php" as the HTTP address. Commented Jun 18, 2015 at 1:12

Shell can also be a server-sided language. Why not just
case "${REQUEST_METHOD:-}/${QUERY_STRING:-}" in (GET/run=true) /path/to/name.sh;; esac? Then let web server software call this, I guess.– user15283025Commented Nov 3, 2021 at 1:12
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 actual HTML Website with a button.
- A php script which executes the script
- A Script
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

1Could you please expand on the need for
?success=true'after the.htmlpart on step 2? Maybe it can be removed? Commented Nov 22, 2019 at 13:58 -
@SOpalajodeArrierez I think your correct, its just there as example Commented Mar 25, 2022 at 21:30
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 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>"

Funny how this solution matches exactly the question, while the highest vote is not. Compliments to you Tino.– LeoCommented May 7, 2022 at 23:12
