Hi Reuti, Andreas,
Yes, forgot to mention the bash versions I have tried: 4.3.46 on Arch Linux
and 4.1.2 on CentOS 6.8.
This is getting weirder: I've found I can replicate the behaviour you are
getting Reuti, if I first do this command:
unset COMMAND_PROMPT
If I want to go back to the behaviour I first experienced (i.e.
Rubbles=barney after running assemble_fam1 then assemble_fam2), then I put
the default COMMAND_PROMPT back:
PROMPT_COMMAND='printf "\033]0;%s@%s:%s\007" "${USER}" "${HOSTNAME%%.*}"
"${PWD/#$HOME/~}"'
Does this work the same for you?
