Any question answered...

Ok I have a program who's screen output I want to redirect to file. I've done this before and use

$myprog.out>>out.txt 2>&1

and for some reason this is not working. I test it with a another simple test program

$myprog.test>>out.txt 2>&1

and it works

I run myprog.out and the output goes to screen as usual but redirecting it seems to fail! It was working and now seems to have stopped WTF is going on!

You're redirecting STDERR to STDOUT with 2>&1.. maybe in the second case the program is writing to STDERR? Not sure what that would work..

Anyway, I think this is that you want:

myprog.out | tee out.txt

tee takes STDOUT and redirects to a file. If you also need STDERR output you can do

myprog.out 2>&1 | tee out.txt
