There are many legitimate or semi-legitimate situations where a .bashrc
file might be read by a shell that's not running inside a terminal.
One of them is if someone chooses to dot in ~/.profile from their
~/.xsession file, or something analogous to it. Or perhaps their
operating system does this automatically in certain kinds of login.
Another might be a scripted ssh session being run from cron, or some
other parent that's not in a terminal. Analogously, the ancient
predecessors of ssh (rsh, rexec) had exactly the same issues.
When adding new commands to your shell dot files, always wrap commands
that assume/require the presence of a terminal in a check for a terminal.
You'll save yourself a *lot* of headaches.
