How to custom display prompt in KornShell to show hostname and current directory?

Question

I am using KornShell (ksh) on Solaris and currently my PS1 env var is:

PS1=\"${HOSTNAME}:\\${PWD} \\$ \"

And the prompt displays: hostname:/fu

Answer 1

ENV=~/.kshrc, and then in your .kshrc:

function _cd {
  \cd "$@"
  PS1=$(
    print -n "$LOGNAME@$HOSTNAME:"
    if [[ "${PWD#$HOME}" != "$PWD" ]]; then
      print -n "~${PWD#$HOME}"
    else
      print -n "$PWD"
    fi
    print "$ "
  )
}

alias cd=_cd

cd "$PWD"
