hashdir

hashdir

A simple tool to calculate the hash of a directory. Only considering it's contents, ignoring all attributes.

Basically a copy of https://github.com/gosimple/hashdir with some improvements, bug fixes & a CLI tool to wrap the library.

CLI Usage

Install the cli tool by downloading the appropriate binary / archive from https://github.com/brad-jones/hashdir/releases

Alternative installation methods:

• HomeBrew: brew install brad-jones/tap/hashdir
• Scoop: scoop bucket add brad-jones https://github.com/brad-jones/scoop-bucket.git; scoop install hashdir;
• Docker: docker pull ghcr.io/brad-jones/hashdir/cli:latest

Then just execute hashdir with a path and an optional hash algorithm (defaults to sha256).

hashdir [-alg md5|sha1|sha256|sha512] /a/path

The hash will be output as a hex encoded string, with no other output, not even a newline.

TIP: A docker run command might look like: docker run --rm -v /a/path:/a/path ghcr.io/brad-jones/hashdir/cli:latest /a/path

Library Usage

Consume the go module like any other.

package main

import (
  "github.com/brad-jones/hashdir"
)

func main() {
  hash, err := hashdir.Make("/a/path", "md5|sha1|sha256|sha512")
  if err != nil {
    panic(err)
  }

  // do something with "hash"...
}
