# Test the umask command. In particular the symbolic modes since they've been
# broken for four years (see issue #738) at the time I added these tests.

# Establish a base line umask.

# Verify that symbolic modifications and output is correct.
#
# When I wrote these tests I based all of the results on the behavior of bash
# when executing identical commands. So if bash has a bug with the umask
# command it's possible fish will as well. However, I did verify the result of
# each interaction and did not find any bugs in how bash or fish handled these
# scenarios.
