  What does ^b in csh do?
• 00:53
  geometry
  I'm looking at a shell inside tmux, accidentally caused a ^b to be sent and it isn't responding.

  It's a tmux escape code, not csh.
• 00:54

  ^b c can create a new window, ^b w can switch windows
• 00:55
  geometry
  Yes, but ^b^b will cause it to send a ^b and the shell's state seems to now be unknown.
• 00:56
  geometry
  Ah, perhaps tmux is in some sort of command-mode.
• 01:01
  LXGHTNXNG
  so the shell received a ^B?
• 01:01
  geometry
  Seems tmux had gotten into some sort of command mode, simply needed a 'q' to be talking to the shell again.
• 01:04
  geometry
  Okay finally archived any history from that shell.

• 01:46
  jan0t

  Now I need to find help with Sendmail (guess how long this installation has been around).
• 03:47
  mason
  geometry: What's your Sendmail doing?
• 03:50
  geometry
  Rather a lot for this site. :-/
• 03:51
  geometry
  In this case a message was rejected by a rule and I'm not too familiar with Sendmail rules.
