Here's an excerpt of my .kshrc. The '$' is printed in red if the last
command failed, $? is preserved in case I want to know the exact value.
---
_nc=$(tput sgr0)
_red=$(tput setaf 1)
---
_ps1_err () {
local _rc=$?
[ "$_rc" -ne 0 ] && printf %s "$_red"
return "$_rc"
}
PS1='\h \w\[$(_ps1_err)\]\$\[$_nc\] '
