Perform export on unix from cgi page

I am not at all proficient in unix or perl or cgi or apache but have been assigned to find a way to set an environment variable on unix from a cgi web page.

I can successfully set the Environment variable

$ENV{PROGPATH}=$Data{PROGPATH};

But when a 4ge program is launched and then itself launches another program, this variable seems to 'go away'. I think I need to run the command

export PROGPATH;

To make it 'stick' for the second program.

I can't seem to find a way to do this successfully from the cgi page that launches the first program.

In Perl, the system command executes any given command intended for the command line. Here, it is necessary to export $PROGPATH and so the full command would be

system("export $PROGPATH");

Note that this might leave your system vulnerable to various attacks, so you may want to ensure that $PROGPATH gets sanity checked prior to this call.

Simple to do:

$ENV{FOO}=1;

system('echo FOO=$FOO');

When Perl runs system, it exports the variables to the forked process.
