Re: How do you set $PS1 on /bin/ksh

In addition to the other recommendations,
don't have the PS1 prompt run commands everytime the prompt is 
generated. For example, you don't need to run commands each prompt to 
figure out your username and hostname as likely they won't or cannot 
change in the same shell session. For example:

PS1='`whoami`$ '

vs.

PS1=`whoami`"$ "
