Good.

Good. So this probably means there's no issue with that script, unless you can isolate a specific minimal example (with some config vars, PS1/PROMPT_COMMAND, etc) which behaves badly.

ble.sh looks pretty not-small, and I'm not familiar with it.

These files load/use ~/.config/dotfiles/osc/osc-prompt.sh which is not linked or provided, and I'm guessing is either the culprit, or the issue is how you use it together with __git_ps1, which I can't help you with.

You may link it in a reply, but I likely don't have the bandwidth to look into it, though maybe someone else would be able to help.

Or, even better, you should look into it and bisect your config.

For what it's worth, if, with that same Tumbleweed live DVD, with git
installed, I add your ~/.bashrc content to mine (default), and add
this final line:
 
  PS1='\n\w$(__git_ps1)\n\$ '
 
then it does work correctly (with your GIT_PS1_* config vars etc).

But your PS1 is:
 
  export PS1='\h:\W$(__osc_prompt) \$ '

So I'm guessing things go wrong somewhere between __osc_prompt and __git_ps1 invocation, but I can't tell where.

Anyway, good luck. avih
