The command shasum --algorithm 512 ${filename1 filename2 ---} is used to calculate the SHA-512 hash values of one or more files.

Here's a breakdown of the command:

• shasum: The primary command for calculating hash values.
• --algorithm 512: Specifies the algorithm to use for computing the hash. In this case, it is set to SHA-512.
• ${filename1 filename2 ---}: The names of the files for which the hash values are to be computed. You can specify multiple filenames separated by spaces. The --- is used to indicate the end of the list of filenames.

By executing this command, the system will generate the cryptographic hash of the files using the SHA-512 algorithm. The hash value is a unique string of characters that represents the content of each file. It provides a way to verify the integrity of the file and detect any changes or corruption.
