I have a little apache2 CGI application on the Ubuntu. The CGI handler is bash shell script.
My client application is search.html:
<html>
<body>
<form action="/cgi-bin/search.sh" method="post">
<input type="text" name="searchKey" size="10"></input>
<input type=SUBMIT value="search">
<form>
</body>
</html>
firstly, I just want to catch value of "searchKey" parameter in server side. I tried like following, but displaying nothing.
search.sh is:
#!/bin/bash
echo Content-type:text/plain
echo ""
echo $SEARCHKEY
Guys, can you tell me how to catch value of the parameter in the server side?
UPDATE
thank you for all answers.I understood that to get a value of post request need to read data from STDIN.
i tried as Ithcy suggest like following
#!/bin/bash
echo post=$(</dev/stdin)
echo 'content length:'$CONTENT_LENGTH
echo 'content:'$post
it was displaying only that:
content length:30
content:
why is content nothing? do i need to do more configure on Apache server to read post data? Thanks

POSTs will come through STDIN.
#!/bin/bash
POST=$(</dev/stdin)
echo $POST
But you really should look at using perl (or python, PHP, etc) if you can, as Glenn Jackman suggests.

The whole querystring is represented in the $QUERY_STRING variable. You can see this by running env without arguments in your shell script.
Example for getting only the searchKey value:
echo $QUERY_STRING | sed 's/searchKey\=\([^&]\+\).*/\1/'
Update: I'm sorry, this only applies if you are using GET to post your form. I didn't read the details =/
If you really need to read POSTs, this page may help you: http://digitalmechanic.wordpress.com/2008/02/21/handling-post-data-in-bash-cgi-scripts/ I didn't get it to work, though.
