How to collect all output in one file

Question

I want to know how to redirect output in linux from the screen to a file? i know it has something to do with using ">" operator?

Answer 1

You can use 2> to redirect it:

foo > stdout.txt 2> stderr.txt

and if you want it in the same file just:

foo > allout.txt 2>&1

This only works in (ba)sh. If you're using a different shell, look for the syntax.
