The command "${command}" is a placeholder that represents a specific command or executable. It is often used in scripting or programming languages to indicate that the actual command should be placed in that position.
The pipe "|" symbol is used to redirect the output of one command to another command. In this case, it takes the output of "${command}" and passes it as input to the "sha384sum" command.
The "sha384sum" command is a cryptographic hash function that calculates the SHA-384 hash value of the given input. It takes the input data from the previous command (represented by "${command}") and calculates its SHA-384 hash. The resulting hash value is then usually displayed on the command line.

never run a command you are not sure if it is safe.
