checksum

Utility to store length, sha1, sha256 hashes of files in dedicated "database" (actually just a JSON file) to verify it later as a part of consistency check with automatic new file indexing.

Description:
    checksum creates database (actually just a JSON file) to store file length, SHA1, SHA256
    to verify file consistency and report if something goes wrong.

Flags:
    --concurrency, -c            Amount of routines to spawn at the same time for checksum verification    (type: int)
                                 Default value is 20 for your system
    --complete                   Completion for shell                                       (type: bool)
    --datadir, -d                Data directory path to run new files scan                  (type: string)
    --database, -D               Database file path (required)                              (type: string)
    --delete-missed              Delete missed files from database                          (type: bool)
    --generate-checksums-only    Skip verification step and add new files only              (type: bool)
    --pattern, -p                Pattern to match filenames which checking for new files    (type: string)
                                 Default is `.(3fr|ari|arw|bay|crw|cr2|cr3|cap|data|dcs|dcr|drf|eip|erf|fff|gpr|iiq|k25|kdc|mdc|mef|mos|mrw|nef|nrw|obm|orf|pef|ptx|pxn|r3d|raf|raw|rwl|rw2|rwz|sr2|srf|srw|x3f)$`
    --skip-failed, --sf          Skip FAIL verification results from output             (type: bool)
    --skip-missed, --sm          Skip MISS verification results from output             (type: bool)
    --skip-ok, --so              Skip OK verification results from output               (type: bool)
    --progressbar                Show progress bar instead of printing handled files    (type: bool)
    --version, -V                Print application and Golang versions                  (type: bool)
    -h, --help                   show help                                              (type: bool)

Why to use checksum but md5sum, shasum and other

checksum provides straight workflow for verification and adding new files processes to avoid remembering something like find $dir | xargs md5sum >> /tmp/database.txt.

checksum automatically:

• verifies files
• adds new
• report about fails and misses
