CGI form values will not automagically become variables in your receiving shell script. According to CGI specification, you need to parse $QUERY_STRING for GET, or read from standard input for parsing POST data.

Unfortunately, unlike environments such as Perl and PHP, you will need to do all this messy things yourself.

Something like this (untested as I don't use bash for CGI):

NAME
cgi_init - Initialize ClearSilver CGI environment SYNOPSIS
#include <cgi/cgi.h> NEOERR *cgi_init (CGI **cgi, HDF *hdf); ARGUMENTS
cgi - a pointer to a CGI pointer hdf_file - the path to an HDF data set file that will also be loaded into the dataset. This will likely have to a be a full path, as the HDF search paths are not yet set up. Certain things, like DESCRIPTION
cgi_init initializes the ClearSilver CGI environment, including creating the HDF data set. It will then import the standard CGI environ- ment variables into that dataset, will parse the QUERY_STRING into the data set, and parse the HTTP_COOKIE into the data set. Note that if the var xdisplay is in the form data, cgi_init will attempt to validate the value and launch the configured debugger on the CGI program. These variables have to be specified in the hdf_file pointed to by hdf_file. The default settings do not allow debugger launching for security reasons. RETURN VALUE
cgi - an allocated CGI struct, including SEE ALSO
