To: Ben Gras <beng@few.vu.nl> Date: Wed, 02 Nov 2005 19:05:13 +0100 Subject: Re: [Minix-devel-l] Symbolic link Using an alias for cd to set the prompt to display the current path breaks the cd command. I use in .ashrc: PS3=$PS1 hostname=$(expr `cat /etc/hostname.file` : '\([^.]*\)') cd() { ## shows current directory as prompt command cd "$@" PS1="$PS3$USER@$hostname:`pwd` > " } If you change the macro in shell.h to: #define SYMLINKS 0 the correct behaviour is restored. Could you verify? I think that the ash package needs the patch.
