.bashrc

# Startup file for interactive non-login shells

# This is getting read for non-interactive shells via ssh
# From bash(1):
#    Bash  attempts  to  determine  when it is being run with its
#    standard input connected to a network connection, as when executed
#    by the remote shell daemon, usually rshd, or the secure shell
#    daemon sshd.  If bash determines it is being run in this fashion,
#    it reads  and executes commands from ~/.bashrc, if that file
#    exists and is readable.  It will not do this if invoked as sh.
#    The --norc option may be used to inhibit this behavior, and the
#    --rcfile option may be used to force another file to be read, but
#    neither rshd nor sshd  generally  invoke  the  shell  with those
#    options or allow them to be specified.
#
# But this should only be used in interactive shells, so make it explicit.
