Useful Options and Examples

tree -L

tree, by default, will recursively list all directories and files as far as it can go. For large directories, it may be best to limit how deep it lists.
This can be done with the 'L' flag, used as tree -L <number of levels>
Note: number must be greater than 0.
1 will list the current director, 2 will list the current and the contents of directories within, and following on with higher levels.

tree -L 1

.
├── README.md
├── template.md
└── tools

tree -d

tree -d will cause tree to only list directories, omitting files within.

tree -L 2 -d

.
└── tools

1 directory

tree -s -h --du

tree -s -h can be used to additionally list the size of files in a human-readable format.
Adding --du additionally lists the size of directories.

tree -L 2 -s -h --du
