Why can't I set PS1?

Why can't I set PS1?

[Wolfgang Hukriede]

Hello,

this is plain vanilla 

	/usr/bin/zsh (ZSH_VERSION=3.0.5)

on equally plain vanilla 

	Linux version 2.0.36 (root@Mandelbrot.suse.de) 
	(gcc version 2.7.2.3) #2 Tue Dec 8 14:58:04 MET 1998

Why can't I set PS1, eg:

hukriede@pfiesteria:/home/hukriede > PS1=xxx
hukriede@pfiesteria:/home/hukriede > echo $PS1
%n@%m:/home/hukriede > 
hukriede@pfiesteria:/home/hukriede > 

???

Many thanks, greetings, W.

It may be the same problem someone else had a couple of weeks ago.  On some
system, the function precmd is set to restore the prompt before every
single command, which is lunacy.  You can probably just `unfunction precmd'
and set your own prompt, if that's the problem.

Yes, it was exactly this. They (Suse GmbH) managed to define in
/etc/profile (which is sourced by zshrc):

        precmd ()
        {
            if test "$UID" = 0; then
                PS1="%m:`pwd -r` # "
            else
                PS1="%n@%m:`pwd -r` > "
            fi
        }

I sent them a bug-report.

Many thanks, fabulous!

Wolfgang.
