I want to use bash for some CGI stuff but cannot seem to get the query
string from the browser. I used bash years ago so I do not know if Apache
or bash itself has changed in this regard. (Please do not suggest another
language, I have written CGI is nearly every language but I must use bash
for this explicit project)

I have tried reading directly from STDIN with read, I have tried
accessing the ENV variables but QUERY_STRING or CONTENT_LENGTH is not
getting set. All the other CGI variables seem to be getting set
correctly.

GATEWAY_INTERFACE is getting set to CGI/1.1 which is correct.

Maybe I am making a bonehead mistake, been doinf EJB/servlets for the
past year, CGI is a bit foggy.

Can anyone give me some suggestions?

Thanks,

Can you run a CGI written in another language ? Try one of the examples
that comes with Apache.  You have to try this first to determine whether
you have a problem with CGI in general (your Apache configuration)
or with bash CGI's in particular.

#!/bin/sh
echo Content-type: text/plain
echo
env

If you append a proper query string to the URL (or GET method for a form)
something should show up in QUERY_STRING.  For example using the above
script with ?hello appended to the url, among env I see:

QUERY_STRING=hello

If you are trying to do POST method, then CONTENT_LENGTH is required
because there is no other way to determine end of data (no newline or
eof).  Looking through the Adv-Bash-Scr-HOWTO in Linux, 'read' would not
work (no way to specify length), but possibly 'dd' which can read a
specified number of bytes (default is from stdin).

Thanks for the help, it ended up being some problems with shared mem
and a custom module we wrote. We upgraded to SuSE 7.2 and some things
got broken.
