Dirdiff

Dirdiff efficiently computes the differences between two directories. It lists files that either:

1. exist only in one of the directories, or
2. exist in both directories but with different content.

Dirdiff is intended to work on large directories, thanks to multi-threading, and by not trying to display the diff of the files' content.

Installation

Released binary

Precompiled binaries for (relatively recent) Linux/amd64 are available for every tagged release.

Install (by compiling from sources) using cargo

cargo install dirdiff-ocamlpro'

Building

Dirdiff is written in Rust. To build it you will need to have the rust toolchain installed.

Once you have obtained the source, the following command will build the binary and put it in the root directory of the repo.

```bash cd dirdiff/ cargo build --release

Copy the binary to the root of the repo

mv target/release/dirdiff dirdiff ```

Usage

``` Usage: dirdiff [OPTIONS]

Arguments: First directory to diff from

Second directory to diff from

Options: -j, --jobs Number of parallel threads to use.

      Use 0 or no option for auto-detection.

  --check-mtime
      Whether to check if the mtime is different.

      Only applies to file whose content is otherwise the same, and gets its specific output tag: `[Differ by mtime only]`.

-L, --follow-symlink Whether to follow symlinks when comparing directories' content

-H Whether to follow symlinks for program's arguments

-h, --help Print help information (use -h for a summary)

-V, --version Print version information ```

Sample output

Columns are tab separated

[Files differ] "foo/bar" [Present in first dir. only] "subdir_a" [Present in second dir. only] "subdir_b"

The diff is outputted to stdout. If symlinks are encountered, a warning will be displayed on stderr.
