Show limited information in bash prompt

.bashrc

If your linux bash prompt (via putty/mobaxterm) is showing the full path of your directory; which can be irritating, update your bashrc's PS1 variables as below to only show the top and bottom 2 directories when there are more than 3

HOST='\[\033[02;36m\]\h'; HOST=' '$HOST
TIME='\[\033[01;31m\]\t \[\033[01;32m\]'
LOCATION=' \[\033[01;34m\]`pwd | sed "s#\(/[^/]\{1,\}/\).*\(/[^/]\{1,\}/[^/]\{1,\}\)/\{0,1\}#\1_\2#g"`'
BRANCH=' \[\033[00;33m\]$(git_branch)\[\033[00m\]\n\$ '
PS1=$TIME$USER$HOST$LOCATION$BRANCH

git_branch () {
  git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/\1/'
}
git_branch is a function which shows current git branch (similar to git bash)
