I am running a system command with backticks, to capture output. However some stderr results were being excluded. So I added a "2>&1" at the end of the system command. this gives me all the output the same as running in a shell prompt, except that the stderr stuff is at the top, and stdout is at the bottom of the returned data. I would like to capture this data as it occurs, the same as it would appear as if I ran the command in my shell.
