sha512sum:tldr:470de
This command uses the ${command}
placeholder to represent any command that can generate an output, and pipes the output of that command to the sha512sum
utility.
The sha512sum
utility calculates the SHA-512 hash value of the input provided to it. A hash value is a unique alphanumeric representation of a data input. SHA-512 is a cryptographic hash function that generates a 512-bit hash value.
By using the pipe (|
) symbol, the output of the ${command}
is passed as input to the sha512sum
command. The sha512sum
then calculates the hash value of the input, which could be a file, a string, or any data generated by the ${command}
.
The resulting hash value, usually a long string of numbers and letters, is displayed in the terminal as the output of this command.
