Ok,

I'm still trying to figure out have to run a program in unix from a cgi script. First I wrote a simple program that printed "hi" in a text file then read the text file and printed it out in html. Then I made it so that `ls` was executed, put in the file and then read and printed out. I did this to be sure I was on the right track. Now I want to run a program called lm. It's a tool which I would like to use to update the status of something. My problem is that in an xterm it works fine but in a browser the lm output never makes it to the file. I suspect it has to do with environment variables but i'm not sure. Here's my test code: 

#!/usr/bin/perl


$hi = `ls`;

`setenv LM_DIR /opt/corp/projects/board_simulation/tools/hw_model-3.4/
+sms/lm_dir`;
`setenv LM_LIB /opt/corp/projects/board_simulation/tools/hw_model-3.4/
+sms/models:/opt/corp/projects/board_simulation/tools/hw_model-3.4/sms
+/maps`;
`setenv VCS_LMC_HM_ARCH sun4.solaris`;
`setenv LMC_PATH /opt/corp/projects/board_simulation/lib/custom_swift_
+v41`;

$lm = `lm show_modeler -m wmers0c3.1`;
$logfile = "lmout.txt";



open (FILE, ">$logfile") or die "I can't open that now\n";
    print FILE "hi";
    print FILE "$hi";
    print FILE "$lm";
close(FILE);



open (FILE, "$logfile") or die "I can't open that now\n";
    while (<FILE>) {
       push @Contents, $_;
    
    }
close(FILE);

print "Content-type: text/html\n\n";
print "<html>\n <head>\n  <title>lm</title>\n </head>\n\n";
print "<body>\n";
foreach $Content(@Contents){
    print "$Content<br>";
    }
print "\n";
print "</body>\n</html>\n";
