 ksh reverse video prompt

That will depend on your terminal type, different terminals will
require different escape sequences.

You will have to embed the actual escape sequence into PS1, first to
set it, then to clear it (or your command output will be reverse too).
To see the characters you need, type these commands:

tput rev | od -c
tput sgr0 | od -c

The output for an xterm for those is:

033 [ 7 m
033 [ m 033 ( B

Other TERM types will have different escape sequences (or maybe not).

The 033 is an escape character, entered by typing ctrl-v ctrl-[

To get a prompt like this: [user@host] /current_dir
in reverse for an xterm, the sequence would be:

PS1='^V^[[7m[${LOGNAME##}@'`uname -n`'] ${PWD}> ^V^[[m^V^[(B'

Pasting that won't work; you have to actually hold the ctrl key and
then press "v" and then "[" in the appropriate places.  Make sure
you use the correct quotes.  Take note of the exact placement of the
forward and reverse ticks.

The result will look like this before you press enter:

PS1='^[[7m[${LOGNAME##}@'`uname -n`'] ${PWD}> ^[[m^[(B'

Have fun.
