treesize is a small command-line utility for listing a directory tree sorted by size. It's main goal is to quickly provide an overview of what is taking up the most space in a tree, so by default it will only list the 5 largest entries in the specified directory (and summarize the rest):
```
treesize . 99.4 MiB (Σ) ├── target 99.4 MiB (Σ) ├── src 13.4 KiB (Σ) ├── Cargo.lock 4.9 KiB ├── README.md 3.2 KiB ├── LICENSE 1.1 KiB └── ... 271 B (Σ) ```
You can use these options to tweak the output listing (traversal of the tree is not affected):
-d <max-depth> Maximal directory depth to recurse, or -1 for infinite [default: 0]
-e <max-entries> Maximum number of entries to display per directory, or -1 for infinite [default: 5]
-s <size-format> How to format node sizes: h/human – powers of 1024, H/si – powers of 1000, r/raw – no
folding [default: human]
For example:
```
treesize -d2 -e3 . 99.4 MiB (Σ) ├── target 99.4 MiB (Σ) │ ├── debug 75.4 MiB (Σ) │ │ ├── deps 53.4 MiB (Σ) │ │ ├── treesize.pdb 10.1 MiB │ │ ├── build 5.0 MiB (Σ) │ │ └── ... 6.9 MiB (Σ) │ └── release 24.0 MiB (Σ) │ ├── deps 18.0 MiB (Σ) │ ├── build 3.6 MiB (Σ) │ ├── treesize.pdb 1.6 MiB │ └── ... 756.7 KiB (Σ) ├── src 13.4 KiB (Σ) │ ├── directory 9.4 KiB (Σ) │ │ ├── print.rs 4.0 KiB │ │ ├── mod.rs 2.6 KiB │ │ ├── filesystem.rs 1.6 KiB │ │ └── ... 1.2 KiB (Σ) │ └── main.rs 4.0 KiB ├── Cargo.lock 4.9 KiB └── ... 4.5 KiB (Σ) ```
Flags that affect the traversal include:
-a List all files (including dotfiles)
-L Follow any symbolic links encountered
--one-file-system Stay in the same file system when listing
