How can I shorten the prompt?

[sunilw]

I know this question has been asked and answered a lot. But I simply haven't been able to successfully do this:

By default the prompt shows the entire path of the current directory. I'd just like to show the current directory instead of the whole path.

If that isn't possible, I'll settle for removing everything except the user and host.

unfortunately the theme doesn't offer a lot of customisation. a work around can be done by replacing the function:

 prompt_dir() {
   prompt_segment blue $CURRENT_FG ' %~ '
 }

by

 prompt_dir() {
   prompt_segment blue $CURRENT_FG ' %CD% '
 }

in (User)/.oh-my-zsh/themes/agnoster.zsh-theme

You can fine more info about configuration customization in this comment

prompt_dir() {
  prompt_segment blue $CURRENT_FG '%C' # get last directory in CWD

  # Or get last 2 directories in CWD (e.g. /dir-one/dir-two)
  prompt_segment blue $CURRENT_FG '%2C' 
  prompt_segment blue $CURRENT_FG '%2~'

}
