Hi folks
I'm wondering if it'd be a good idea to have PS1 set to
'${debian_chroot:+($debian_chroot)[EMAIL PROTECTED]:$(realpath "$(pwd)")\$ '
instead of the default
'${debian_chroot:+($debian_chroot)[EMAIL PROTECTED]:\w\$ '
and make it a suggestion in /etc/skel/.bashrc for those users who want
to see the actual current working directory.
From a security standpoint you could enter e.g.
/home/someoneelse/somedir/ and see [EMAIL PROTECTED]:/home/someoneelse/somedir/$
in the prompt, but really be in /etc/ if somedir is a (potentially
malicious) symlink to /etc created by a different user. It could get
quite disastrous if you decide to run something like rm -r * in such a
directory.
It won't be very helpful with more sophisticated symlink race
conditions, but it is better than nothing.
Perhaps I should post it to bash package wishlist, what do you think?
