DDH traverses input directories and their subdirectories. It also hashes files as needed and reports findings.
The H in "hTool" is silent. The H in its abbreviation, "DDH," is not.
This tool is called DDH for two very good reasons.
- DDT is a dangerous pesticide
- I mistyped when I created the project
DDH is usable both as a library and as a stand alone CLI tool and aims to be simple to use in both cases.
let (files, errors): (Vec<Fileinfo>, Vec<(_, _)>) = ddh::deduplicate_dirs(dirs);
let (shared, unique): (Vec<&Fileinfo>, Vec<&Fileinfo>) = files
.par_iter()
.partition(|&x| x.get_paths().len()>1);
process_full_output(&shared, &unique, &files, &errors, &arguments);- Install Rust
cargo install --git https://github.com/darakian/ddh ddh- The DDH binary will be installed into
$CARGO_HOME/.bin/ddh, which usually is$HOME/.cargo/bin/ddh. This should be in yourPATHalready if you're using rustup.
DDH supports both a standard output for human comprehension and a parsable json output for custom tools such as ddh-move.

Compare and contrast directories.
Example invocation: ddh /home/jon/downloads /home/jon/documents -f duplicates
Example pipe: ddh ~/Downloads/ -o no -v all -f json | someJsonParser.bin
USAGE:
ddh [OPTIONS] <Directories>...
FLAGS:
-h, --help Prints help information
-V, --version Prints version information
OPTIONS:
-b, --blocksize <Blocksize> Sets the display blocksize to Bytes, Kilobytes, Megabytes or Gigabytes. Default is
Kilobytes. [possible values: B, K, M, G]
-f, --format <Format> Sets output format. [possible values: standard, json, off]
-o, --output <Output> Sets file to save all output. Use 'no' for no file output.
-v, --verbosity <Verbosity> Sets verbosity for printed output. [possible values: quiet, duplicates, all]
ARGS:
<Directories>... Directories to parse
DDH works by hashing files to determine their uniqueness and, as such, depends heavily on disk speeds for performance. The algorithmic choices in use are discussed here.
