Linux command to print directory structure in the form of a tree?

Question

Is there any linux command that I can call from a Bash script that will print the directory structure in the form of a tree, e.g., folder1 a.txt b.txt folder2 folder3

Answer 1

You can try this: ls -R

ls -aR if you need hidden files.

ls -lR if you need date/time modified and permission info.
