Hi.
First, I have completed chapter 6 and nothing special arrives ; so, it seems
to me that just the PS1 variable was affected.
Secondly, In /etc/bash.bashrc (on my debian/wheezy host), I have commented
the folloing lines :
if [ -z "$debian_chroot" ] && [ -r /etc/debian_chroot ]; then
debian_chroot=$(cat /etc/debian_chroot)
fi
PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
and I inseted this one :
PS1='\u:\w\$ '
Then, I created a new group and a new user with the commands in teh book and
I obtained the wanted prompt.
Many thanks for your help.
