rdm - Recursive Directory MD5

rdm is a command-line tool written in Rust that can recursively calculate the md5 value of a directory.

Installation

You can download precompiled binaries from here, or use cargo to install:

cargo install --git https://github.com/padeyao4/rdm.git

Usage

rdm [OPTIONS] <DIR>

where <DIR> is the directory to calculate the md5 value.

The optional arguments are:

-j, --json: Print json formatted output, including the md5 values of each file and subdirectory.
-a, --all: Include hidden files and directories in calculation. By default, they are ignored.
-h, --help: Print help information.

Example

Assume there is a directory structure like this:

test/
├── a.txt
├── b.txt
└── sub/
    ├── c.txt
    └── d.txt

Running rdm test will produce output like this:

0a7c8f6b9e2d3a0b9c7f8d6e4f3a2c9d

Running rdm -j test will produce output like this:

{
  "name": "test",
  "hash": "0a7c8f6b9e2d3a0b9c7f8d6e4f3a2c9d",
  "children": [
    {
      "name": "a.txt",
      "hash": "4124bc0a9335c27f086f24ba207a4912"
    },
    {
      "name": "b.txt",
      "hash": "47bce5c74f589f4867dbd57e9ca9f808"
    },
    {
      "name": "sub",
      "hash": "1fb8beedfcabfdffddbbdcdeecdfcd03",
      "children": [
        {
          "name": "c.txt",
          "hash": "1fb8beedfcabfdffddbbdcde74f589f4"
        },
        {
          "name": "d.txt",
          "hash": "1fb8beedfcabfdffddbbdcd47bce5c74"
        }
      ]
    }
  ]
}
