how does the system command work?

[Horrid]

I am trying to run an exe from a perl CGI script.
I am trying to use a system("apppath/appname&quot command but nothing ever happens. Are there any special things I need to do before a system command? Is it possibly to call an EXE from a CGI script?

could someone post an expample of running something as simple as notepad please.

Thans in advance

a better question might be 'how do I get information about Perl functions?'. That answer is .....

prompt>perldoc -f system<return>

read what is produced.

I'm not trying to be short. But, that utility will help more than I can.

The is a FAQ on using Perl's built in documentation - faq219-321

Ok, the problem is probably in your path to the CGI script. Your web server (if it's secure) probably only allows CGI programs to see stuff in the /var/

http://www/html

or whatever directory you're in, that is, as far as the web server knows, /var/

http://www/html

is the root of the whole system. So, if you try to run a program in /usr/local/bin/myProg it won't work. This is because your webserver looks in /var/

http://www/html/usr/local/bin/myProg

because the root of the system is at /var/

http://www/html.

If you're using windows, it's something like c:\

http://wwwroot\

or whatever.

Also, your web server permissions or file permissions may not be set to let you do that. If you needm ore advice, post the code, OS and web server you're using.

MWB. As always, I hope that helped!
