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

From reading the ksh man page you want

PS1="${HOSTNAME}:\${PWD##*/} \$ "

Tested on default ksh on SunOS 5.8
