I want to trigger execution of a server-side script (.sh file) from JavaScript code running in a web browser.
I've searched google and no code that I've found is working for me.

Is this on the server or in the browser? And if it's in the browser, where is the sh file located: at the user's machine or on your server? Need more info.slebetman– slebetman2012-08-14 02:59:03 +00:00Commented Aug 14, 2012 at 2:59

If this is client-side js, you need to use ajax or an html form to communicate with a server-side controller (which would be written in whatever language(s) you are using. e.g, PHP, Rails, Python, etc.).Matthew Blancarte– Matthew Blancarte2012-08-14 03:38:38 +00:00Commented Aug 14, 2012 at 3:38

You need to first make a file in a server-side language (like PHP, Python, RoR, PERL, ASP.NET, or JSP) that runs the .sh file. Then you have to use Ajax to request that page.
In PHP, something like:
<?= shell_exec('sh /home/user/public_html/scripts/script.sh'); ?>
Then, for JS, something like:
<script src="//code.jquery.com/jquery-1.8.0.min.js"></script>
<script>
var runShellScript = function () {
$.get('/scripts/script.php', function () {
alert('Shell script done!');
});
};
// Some stuff
runShellScript();
</script>
If you don't want to use jQuery or Ajax, you could probably get away with JSONP.

i cannot execute for the script.php. and i am using apache

Apache should let you run PHP files.

What is the default path for "/scripts/script.php" ?
I believe You can't do this directly with client side JavaScript. However, you can invoke an url request to let server side language (PHP, Java, Ruby... almost any language) to do the task. And be sure to consider security issues.

Make sure you .sh file begins with:
#!/bin/sh
echo "Content-type: text/html"
echo ""
and the .htaccess file is set up to execute .sh files:
Options +ExecCGI
AddHandler cgi-script sh
Then you can simply call the file from the url using XMLHttpRequest. http://en.wikipedia.org/wiki/XMLHttpRequest, and maybe even have your script return some json object.

I don't know if Javascript opens .sh files in particular, but you can use the filereader API to open files in general.
