Hi, I need to set stdout to go to a String variable, has anyone got any ideas?

I'm not sure I grasp your question. You're trying to read from stdout??

I want to change stdout to instead of displaying on a monitor put it in a variable.

I think you mean this:

#!/bin/ksh

myDirectory="$(pwd)"

echo "This is my current directory->[${myDirectory}]"

Basically i have a fork and a execl i need to send the output of the execl instead of onto the screen, into a variable. I need to do this as the need to send it over a socket. I have writing the program in C and C++

Instead of execl use popen - it does just what you want.

man popen.
