a tree command using Shell Script that displays all the directories recursively

[apollo]

Good day dear Python-experts, hello everyone


hope that youre all right and all goes well at your side.

i want to simulate a tree command using Shell Script that displays all the directories recursively in this format:

.
|-- Lorem
|-- Lorem
|-- Lorem
    |-- Lorem
    |-- Lorem
|-- Lorem
`-- Lorem
 

how can this be achived?

note: i want to do this on a MX-Linux system - well i can do this with Tree - but wait. I guess that tree has to be installed first..
