Informative bash prompt

I hop between machines a lot at home. I want to know their IP address easily in addition to history count, user, and (if available) git branch in my .basrg

export PS1='($IP) [\!]\[\033[00;32m\]\u\[\033[01m\]@\[\033[00;36m\]\h\[\033[01m\]:\[\033[00;35m\]\w\[\033[00m\]\[\033[01;33m\]`git branch 2>/dev/null|cut -f2 -d\* -s`\[\033[00m\]\$ '

modifications to up scripts for vpn

In the scripts in etc/ppp/ip-up.d you can use

When the ppp link comes up, this script is called with the following
parameters
      $1      the interface name used by pppd (e.g. ppp3)
      $2      the tty device name
      $3      the tty device speed
      $4      the local IP address for the interface
      $5      the remote IP address
      $6      the parameter specified by the 'ipparam' option to pppd

Silly I missed that.
