830N/A# Algorithm:

830N/A# 1. Define "ellipsis", either Unicode #2026 for unicode locales

830N/A# and "..." otherwise

830N/A# ([[ "${LC_ALL}/${LANG}" = ~(Elr)(.*UTF-8/.*|/.*UTF-8) ]]

830N/A# ensures that the pattern matches the leftmost sequence

830N/A# containing *.UTF-8, allowing to match either LC_ALL or

830N/A# LANG when LC_ALL is not set)

830N/A# 2. If PWD is within HOME replace value of HOME with '~'

830N/A# If the PWD is longer than 30 charatcers shorten it to 30 chars

830N/A# print '#' for user "root" and '$' for normal users

830N/A# Notes:

830N/A# - printf "%*s\r%s" COLUMNS "") # is used at the beginning to

830N/A# work around a bug in the "multiline" handling code which

830N/A# causes the shell to override its own prompt when the edit

830N/A# line overflows (this happens if the terminal cursor

830N/A# position is not 0 when PS1 is printed).

830N/A# - PS1 will initially be empty until either...

830N/A# a) ... someone sets the variable

830N/A# or

830N/A# b) ... the prompt is displayed for the first time (default is

830N/A# '$ ' for normal users and '# ' for user "root")

830N/A# - The statement below will not work if someone sources /etc/ksh.kshrc

830N/A# unless PS1 gets "unset" first.

830N/A# - Make sure to use absolute paths (e.g. /usr/bin/hostname) to make

830N/A# sure PS1 works in cases where PATH does not contain /usr/bin/

830N/Aif [[ "$(set)" != ~(E)PS1= && "${PS1}" == '' ]] ; then

830N/A printf "%*s\r%s" COLUMNS ""
