tree command

tree [directory]

Displays a directory and all its subdirectories in a tree-like view. This makes it easy to see the structure of the file system at a glance.

What it does

• Starts at the given directory (or the current directory if none is given).
• Recursively lists all subdirectories and files.
• Uses branches (├──, └──, │) to show hierarchy.
• Prints a summary at the end with the total number of directories and files.

Usage

tree
tree /programs
tree /system/webserver

Notes

• If no directory is specified, tree starts at the current working directory.
• If the current directory is empty, nothing is printed except the summary.
• Works with any mounted filesystem, including /ramdisk.
