Hey,

Just a question regarding cgi perl scripts running on Unix systems.

I have a section of code, which opens a handle on the "w" command on a unix system, the idea being to see who is currently logged on at the moment.
open(CMD, "w|"); @list = <CMD>; close(CMD); foreach(@list) { print "$_\n"; }

however, this bit of code works from the command line (it prints out the entire command output) but from the browser (when run as a cgi-script), it only shows about 8 lines, where they are far more users on.

Is there some kind of admin restriction on such a thing?

Thanks for any help

That line works fine on a machine here, with 15 users. Wonder if its a buffer thing, and that you should be using something like ...
while( <CMD> ) { print "$_\n"; }
.. instead?
