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.

Usage

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 8 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 not shasum/md5sum/etc.?

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

checkum automatically:

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