22 # By default this file is sourced for ALL ssh commands. This is wonky.
23 # Normally, this file is not sourced when a script is run, but we can
24 # override that by having #!/bin/bash -l. I want something similar for ssh
25 # commands. when a local script runs an ssh command, this file should not be
26 # sourced by default, but we should be able to override that.
28 # so here we test for conditions of a script under ssh and return if so. To test
29 # for an overriding condition, we have a few options. one is to use an
30 # environment variable. env variables sent across ssh are strictly limited. ssh
31 # -t which sets $SSH_TTY, but within a script that won't work because tty
32 # allocation will fail. We could override an obscure unused LC_var, like
33 # telephone, but I don't want to run into some edge case where that messes
34 # things up. we could transfer a file which we could test for, but I can't think
35 # of a way to make that inherently limited to a single ssh command. I choose to
36 # set SendEnv and AcceptEnv ssh config vars to allow the environment variable
37 # BASH_LOGIN_SHELL to propagate across ssh.
