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 and ~/.bashrc, if these files exist and are 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.
