Quick Linux tip:
Most people use tree to visualize a directory structure.
What many don't know is that it can also display file permissions, owners, groups, and sizes.
$ tree -pugh -L 3
Here is what each option mean:
-p - file permissions
-u - owner
-g - group
-h - human-readable sizes
-L - limit the depth of the directory tree
This is especially useful when auditing file permissions, troubleshooting access issues, or documenting a project's directory structure.
