Thanks again.
I'm guessing your script will work if you change this line:

my $filename = $q->param('/home/yifangt/hello.cgi');

into

my $filename = '/home/yifangt/hello.cgi';

But that's not how you want it to work. You want the actual parameter name inside param(). See my last post on how that parameter name is decided.

Hope that works,

Dave

UPSIMAGE.CGI(8) 						    NUT Manual							   UPSIMAGE.CGI(8)

NAME
upsimage.cgi - Image-generating helper for upsstats.cgi SYNOPSIS
upsimage.cgi Note As a CGI program, this should be invoked through your web server. If you run it from the command line, it will either complain about unauthorized access or spew a PNG at you. DESCRIPTION
upsimage.cgi generates the graphical bars that make up the right side of the page generated by upsstats.cgi(8). These represent the current battery charge, utility voltage, and UPS load where available. The images are in PNG format, and are created by linking to Boutell's excellent gd library. ACCESS CONTROL
upsstats will only talk to upsd(8) servers that have been defined in your hosts.conf(5). If it complains about "Access to that host is not authorized", check that file first. FILES
hosts.conf(5) SEE ALSO
upsd(8), upsstats.cgi(8) Internet resources: The gd home page: http://www.boutell.com/gd/ The NUT (Network UPS Tools) home page: http://www.networkupstools.org/ Network UPS Tools 05/22/2012 UPSIMAGE.CGI(8)
