b2sum: Calculate a BLAKE2 checksum from `stdin`.

${command}

$ ${command} | b2sum

try on your machine

This command is a Unix/Linux command used for generating the BLAKE2 cryptographic hash value of the output of the specified command.

Here's how the command works:

${command} is a placeholder for the actual command that you need to execute. It can be any command that produces output, such as ls, cat, or a complex pipeline of multiple commands. This command will be executed and its output will be fed as input to the next part of the command.
The pipe symbol | is used to redirect the output of the command ${command} to the input of the b2sum command.
b2sum is the command for computing the BLAKE2 hash value. The BLAKE2 algorithm is a modern cryptographic hash function that provides high security and performance. When used with the pipe, it takes the output of the ${command} and computes the BLAKE2 hash value for that output.

By combining these elements, the command ${command} | b2sum executes the specified ${command} and calculates the BLAKE2 hash value for its output.

Please note that the b2sum command needs to be installed on your system for this command to work.
