b3sum:tldr:a5ddb

This command is used to calculate the b3sum (BLAKE3 hash) of one or more files and save the result into a separate file.

Here's a breakdown of the different parts of the command:

• b3sum: This is the command to calculate the b3sum hash.
• ${filename1 filename2 ---}: These are placeholders for the file names or paths of the files you want to calculate the b3sum hash for. You can replace ${filename1 filename2 ---} with the actual file names or paths, separated by spaces. The --- signifies the end of the file names and indicates that there are no more file names specified.
• >: This is a redirect operator, used to redirect the output of a command to a file instead of printing it in the terminal.
• ${filename-b3}: This is a placeholder for the desired file name or path where you want to save the b3sum hash result. You can replace ${filename-b3} with the actual file name or path you wish to use.

By executing this command, the b3sum command will calculate the b3sum hash for the specified files (filename1, filename2, etc.), and the resulting hash value will be saved into a file with the name or path specified by ${filename-b3}.
