rhash: Recursively process a directory to generate an SFV file using SHA1.

rhash

$ rhash --sha1 --recursive ${path-to-folder} > ${path-to-output-sfv}

try on your machine

The command rhash is a utility for computing and verifying various hash functions. In this specific command, it is being used to calculate the SHA-1 hash values for all the files within a specified folder recursively.

Let's break down the command step by step:

rhash: This is the command itself, indicating that we want to use the rhash utility.
--sha1: This option specifies that we want to compute the SHA-1 hash values of the files. SHA-1 is a cryptographic hash function that generates a 40-character hexadecimal hash code for a given input.
--recursive: This option tells rhash to search for files recursively within the specified folder; meaning it will include all subdirectories and their contents.
${path-to-folder}: This is the placeholder for the actual path to the folder you want to hash. You need to replace ${path-to-folder} with the actual path, for example: /home/user/Documents.
>: This symbol redirects the output of the command to a file instead of displaying it on the terminal.
${path-to-output-sfv}: This is the placeholder for the path to the output file where you want to store the hash values. You need to replace ${path-to-output-sfv} with the actual path and filename, for example: /home/user/hashes.sfv.

In summary, running this command will calculate the SHA-1 hash values for all files within the specified folder and its subdirectories. The hash values will be saved in the specified output file.
