The command "b3sum ${filename1 filename2 ---}" computes the Blake3 hash checksums of one or more files indicated by the filenames provided.

Here's a breakdown of each part of the command:

• "b3sum": This is the name of the command or utility that calculates the Blake3 hash checksum. It refers to the specific implementation of the Blake3 hashing algorithm.
• "${filename1 filename2 ---}": This portion represents the list of files for which the hash checksum needs to be calculated. The filenames are separated by spaces. The usage of "---" indicates the end of the list of filenames and is optional. It is used when filenames might start with a hyphen (-) to avoid confusion with command options.

Overall, running this command will compute the Blake3 hash checksums of the specified files and display the results. The output will likely be a series of hexadecimal characters representing the checksums for each file.
