sha256sum: Calculate the SHA256 checksum for one or more files.
$ sha256sum ${filename1 filename2 ---}
try on your machine
This command is using the SHA-256 hashing algorithm to generate a checksum (or hash) for multiple input files. Here's a breakdown of the command:
sha256sumis the name of the command-line utility used to calculate SHA-256 hashes.${filename1 filename2 ---}is a placeholder for the actual filenames you would provide as arguments to the command. The---indicates that you can include any number of filenames separated by spaces.
By executing this command with file(s) specified, it will calculate the SHA-256 hash for each file individually, displaying the resulting checksum along with the corresponding file name. These checksums can be used to verify the integrity of files, as even small changes to a file will produce a drastically different hash value.

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