Run a shell script with an html button
I want to launch a bash script when a 开发者_开发问答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?
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, ...
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
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');
?>
Reference: http://php.net/manual/en/function.shell-exec.php
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>"
