Docker tmux issue

I installed Parrot OS as a docker container and when I run tmux in it, the prompt string changes. It acts like an eyesore to an OCD person. I don't really know what the issue could be called exactly so can't mention the term, sorry for that.

In the image, they are two different containers of Parrot OS, with tmux running in upper container. I think the issue is understandable from the image.

Solution

  • This is because tmux is not aware that your terminal support UTF-8. Either:

    • Add the -u flag to tmux (tmux -u new or tmux -u attach); or

    • Make sure your system is in a UTF-8 locale and the environment variables are set correctly (LANG, LC_ALL and so on).
