Interesting! The idea that "everything in linux is a file" is still abstract to me. But it does help with my understanding to know that "every file has a number called FD (file descriptor)" and that a screen also a file descriptor. Additionally, we can also do chained redirection!

[@karips49]

Perfect tutorial! I have a minor question: Why instead of: ls Documets ABC > dirlist 2>&1 cannot I use?: ls Documets ABC > dirlist 2> dirlist Is there a reason to use the file descriptor instead of the actual name of the file? Thanks in advance!

[@xrafter]

Because fd 1 is stdout of the terminal

[@tsilikitrikis]

Good point man. I actually tried that and it was made the same result but in different order (The stoutput was at the top and the error was below that. If I typed with 2>&1 the order was reversed) So I suspect that if you want to redirect both output and error at the same time is faster to use 2>&1 but if you want to write error in different file name you use >nameOfFile. Great point again!
