Description

checksum-tools is a dual-purpose tool to generate or verify checksums of various types for a set of files in a given directory.

Options

-a, --action ACTION

Valid choices are generate and verify. In generate mode, a digest file is created for each content file processed. In verify mode, the digests in digest files are verified against the content files and PASS/FAIL information written to standard output. Default: verify.

-c, --config FILE

Load default configuration values from FILE. Default: a file called .checksum-tools in the user's home directory. Options specified on the command line will override any defaults in the configuration file.

-d, --digest DIGEST

In generate mode, specifies the type of digest to generate. Valid options depend on the Ruby libraries available on the system, but usually include md5, sha1, sha256, sha384, and sha512. Default: md5. Including this option multiple times causes multiple digests to be generated for each file.

-D, --digest-types

Display the available digest types for the specified target directory/path/system.

-e, --extension EXT

The file extension to be appended to the names of content files when generating digest files. Default: .digest.

-f, --filemask MASK

Generate or verify checksums for files matching MASK. Include this option multiple times to match multiple filemasks. Default: * (all files)

-n, --no-action

Dry run — display configuration options and exit.

-o, --overwrite

Overwrite existing digest files with newly-generated ones.

-q, --quiet

Do not display a progress bar for each file generated.

-r, --recursive

Recurse into subdirectories.

-v, --version

Print version number and exit.

-x, --exclude MASK

Exclude files matching MASK from the operation. Can be used to skip a certain subset of files otherwise included using the --filemask option.

-h, --help

Display a simple help message and exit.
