RE: problem running cli program from perl cgi script..

Title: RE: problem running cli program from perl cgi script..

Unfortunately the script still acts funny!

It executes fine from command line, but when I pull it on the web browser it just hungs there...

the task manager shows perl.exe, cmd.exe and get_events.exe running till who knows when... I have to kill them to make them stop... It does create the event.txt file but it is empty.

If you guys have any more ideas on this I would really really appreciate it...

Thank you

I'd suggest using single quotes around the $get_events string or if you need variable interpolation of "machine1" then change the system call to something like:

        @args = ("get_events.exe","--sensor machine1","--save event.txt");
        system(@args) == 0 or die "system @args failed: $?";

Just off the top of my head. I did not debug your code. The above code is much more reliable when executing system commands. You might also have to fully qualify the path to "get_events.exe" if it is not in the system path.

Ok this is the code... it's only couple of lines calling the command line
program...

#!/usr/bin/perl -w

        my $get_events = "get_events.exe --sensor machine1 --save
event.txt";
        system($get_events);
print "This is the system result $?";

When I run the script from command line the value I get from the system call
is 0, which means that get_events executed fine.
Nothing happens though when I run the script through cgi... it just hungs
there... on the task manager i see get_events.exe running...

Thanks again!

Its hard to tell without some source code. What does $! say? Are you
checking the return status of the system call?
