Using shell_exec

[netfrugal]

Here is a simple command I pass into the shell_exec() function, which simply lists all docs inside a directory:

echo shell_exec("ls");

I have run into a problem of doing the same thing with active/dynamic content in a linux environment.

In other words, I don't think shell_exec() works if the data is constantly being refreshed.

My example:

echo shell_exec("nload -m eth1");

"nload" is the gui version of monitoring bandwidth.

I'm only guessing this, but does anyone know if my hypothesis is true?

technically it should work for the instant the instance is called... what does it return when you call it?
