Why is this mercurial error not in stderr?

Question

Running hg branch from a random location without a repository results in the following output:

$ hg branch
abort: no repository found in '/home/abe' (.hg not found)!
abort: no repository found in '/home/abe' (.hg not found)!

I don't want to see these errors so I tried hg branch 2>/dev/null resulting in the following:

$ hg branch 2>/dev/null
abort: no repository found in '/home/abe' (.hg not found)!

Where is this line coming from if not stderr? I figured mercurial may echo these errors to standard output as well, so I tried $ hg branch 2>&1 | awk '{print "test: "$0}' resulting in:

$ hg branch 2>&1 | awk '{print "test: "$0}'
test: abort: no repository found in '/home/abe' (.hg not found)!
abort: no repository found in '/home/abe' (.hg not found)!

What I want to do is run hg branch and get either the name of the branch I'm in, or no output at all. Any ideas?

Answer 1

I'm an idiot.

I attempted to add hg branch to my PS1, so I'd know what branch I'm working on while in the terminal. The first error was a remnant of a previous attempt in my .bashrc.

Silly mistake as always :) Thanks anyway guys!
