Revision as of 00:13, 12 May 2010

my personal (zsh) prompt setups has, on one line

  • last job exit status (invisible when zero)
  • host:path in network friendly (ish) format
  • path shortening to last three components, plus subtle visual indication when this occurs
    • this shortening balances path context needs with space limitations. and is why the preceeding 'network friendly' format is "ish" :)
  • path colourisation to indicate whether $PWD is RW or not (not usually means RO, but may also mean 'directory does not exist')
  • count of background jobs (invisible if zero)
  • ^ and $ reminder mnemonic for regex start/end line matching (I have a dyslexia about this!)
  • live time and load average (load gets dynamic colourisation also, but is invisible below threshold (set to 0.3 for me)
    • for values of "live" that = "20 second refresh"
    • this refresh ensures that an abandoned prompt will keep-alive a remote shell over dodgy NAT :)
  • current tty

ideas I don't currently implement


here is my prompt:
