b3sum: Calculate a BLAKE3 checksum from `stdin`.
$ ${command} | b3sum
try on your machine
This command is using the pipe symbol (|) to send the output of the command preceding it (${command}) as input to the b3sum command.
In general, the pipe symbol is used in a Unix-like operating system to redirect the output of one command to another command as input. In this case, the output of ${command} is being directed to the b3sum command.
The b3sum command is a hashing utility that calculates a 256-bit BLAKE3 hash of the input data. It is used to generate a unique identifier (hash) for files or data, which can be useful for verifying data integrity or comparing files.
So, the overall command is taking the output of ${command} and passing it as input to b3sum, which will then calculate the BLAKE3 hash of that input data.
