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

HOST=`hostname`
PS1='$(print -n "[${USER}@${HOST%%.*} ";[[ "$HOME" == "$PWD" ]] && print -n "~" ||([[ "${PWD##*/}" == "" ]] && print -n "/" || print -n "${PWD##*/}");print "]$")'
