The command ${command} | shasum is a Unix command that consists of two parts separated by the pipe symbol (|).
-
${command} represents a variable that should be replaced with an actual command. This part of the command is executed first, and its output is then passed to the next part of the command.
-
| (pipe) is a Unix operator that redirects the output of the preceding command to be used as input for the following command.
-
shasum is the command that comes after the pipe symbol. It is used to calculate a checksum or hash value of the input data.
In summary, the overall command takes the output of ${command} and passes it as input to the shasum command, which then calculates the hash value of the data received from ${command}.
