Usage:

• checksums [options] FILES

checksums is a utility to verify the integrity of a file using a CRC32 checksum stored in the file name. A CRC32 checksum is an 8 character hexadecimal string. This is a common practice used by Anime sub releases.

When checking the checksum, the following file name formats are recognized:

• ...[checksum]...
• ...(checksum)...
• ..._checksum_...

When appending the checksum to the file name, the bracketed (first) format is used.

Options:

• --version: show program's version number and exit
• -h, --help: show this help message and exit
• -c, --check: Compute the checksum and try to match it to the file name using one of the formats listed above.
• -a, --append: Compute the checksum and append it to the the file name, just before the file extension.
• -v, --verbose: Print extra information

FILES is the list of files to preform the action on. This can be a single file, multiple files, or a glob if your shell supports it.

Examples:

• checksums -a report.txt image.png *.xml
• checksums -c *.mkv
• checksums video-\[1004456E\].3gp
