positional arguments:

directory

Directory to hash.

optional arguments:

-h, --help

show this help message and exit

-v, --version

show program's version number and exit

-a , --algorithm

Hashing algorithm to use, by default "md5". Always available: ['md5', 'sha1', 'sha224', 'sha256', 'sha384', 'sha512']. Additionally available on current platform: ['blake2b', 'blake2s', 'md4', 'md5-sha1', 'ripemd160', 'sha3_224', 'sha3_256', 'sha3_384', 'sha3_512', 'sha512_224', 'sha512_256', 'shake_128', 'shake_256', 'sm3', 'whirlpool']. Note that the same algorithm may appear multiple times in this set under different names (thanks to OpenSSL) [https://docs.python.org/2/library/hashlib.html]

Filtering options:

Specify what files and directories to include. All files and directories (including symbolic links) are included by default. The --match/--ignore arguments allows for selection using glob/wildcard (".gitignore style") path matching. Paths relative to the root `directory` (i.e. excluding the name of the root directory itself) are matched against the provided patterns. For example, to only include python source files, use: `dirhash path/to/dir -m "*.py"` or to exclude hidden files and directories use: `dirhash path/to.dir -i ".*" ".*/"` which is short for `dirhash path/to.dir -m "*" "!.*" "!.*/"`. By adding the --list argument, all included paths, for the given filtering arguments, are returned instead of the hash value. For further details see https://github.com/andhus/dirhash/README.md#filtering

-m

[ ...], --match [ ...] One or several patterns for paths to include. NOTE: patterns with an asterisk must be in quotes ("*") or the asterisk preceded by an escape character (\*).

-i

[ ...], --ignore [ ...] One or several patterns for paths to exclude. NOTE: patterns with an asterisk must be in quotes ("*") or the asterisk preceded by an escape character (\*).

--empty-dirs

Include empty directories (containing no files that meet the matching criteria and no non-empty sub directories).

--no-linked-dirs

Do not include symbolic links to other directories.

--no-linked-files

Do not include symbolic links to files.

Protocol options:

Specify what properties of files and directories to include and whether to allow cyclic links. For further details see https://github.com/andhus/dirhash/DIRHASH_STANDARD.md#protocol

-p

[ ...], --properties [ ...] List of file/directory properties to include in the hash. Available properties are: ['name', 'data', 'is_link'] and at least one of name and data must be included. Default is [data name] which means that both the name/paths and content (actual data) of files and directories will be included

-c, --allow-cyclic-links

Allow presence of cyclic links (by hashing the relative path to the target directory).

Implementation options:

-s CHUNK_SIZE, --chunk-size CHUNK_SIZE

The chunk size (in bytes) for reading of files.

-j JOBS, --jobs JOBS

Number of jobs (parallel processes) to use.

Special options:

-l, --list

List the file paths that will be taken into account, given the provided filtering options.
