  23 # info bash covers everything comprehensively of course.  i use ~/.bash_profile
  24 # to source bashrc, and .profile just echos that the normal bash startup process
  25 # is not happening.  I don't source bashrc in posix mode based on debian's
  26 # default, and posix mode is quirky, doesn't seem worth figuring it out This
  27 # setup ensures no distro can override anything, as they occasionally do things
  28 # I don't like. For example, debian's root .profile spamms with "mesg n"when
  29 # there is no tty. The mesg n ensures the terminal is not writable by other
  30 # users, but it is that way without the mesg n, and google search, and debian
  31 # wiki search, /usr/share/doc search gives no justification for it, and it's not
  32 # in fedora, so I'm pretty confident that it is useless redundant security, plus
  33 # it is purposefully in a user startup file, not a system one, so intended for
  34 # the user to change.

  36 # History related options first, or else
  37 # we risk screwing up history history. And this is duplicated
  38 # in ~/.bash_profile just for good measure
