 868 #
 869 # So, in my bashrc, test for conditions of noninteractive ssh and return
 870 # if so.  And we don't keep the rest of the code in .bashrc, because
 871 # even though we return, we parse the whole file which can cause errors

 873 #
 874 # To test for an overriding condition: bash builtin vars and env show no
 875 # difference in ssh vs local, except shell level which is not
 876 # reliable. one option is to use an environment variable. env variables
 877 # sent across ssh are strictly limited. We could override an obscure
 878 # unused LC_var, like telephone, but I don't want to run into some edge
 879 # case where that messes things up. I choose to set SendEnv and
 880 # AcceptEnv ssh config vars to allow the environment variable BRC to
