No,
> /dev/null 2>&1is. If try your example but with file instead null, stderr content not in file.Because x>y not redirect x to y, but duplicate y and set x to y-duplicate. See bash manpage REDIRECTION (your example in that section for what not work).
As i understand, your example set 2 to what 1 is, then set 1 to null. Now 2 not null, but what 1 before.
So, the joke is that it should hide all output.
Yes it do, your example do too. But if test thing and replace null with file, suddenly stderr missing. Happen to me, 5h debug session. Hope to help prevent that for other people.
