Hash files

This command will get the SHA 512 hash for each file in the current directory and write it to the file you specify.

shasum -a 512 * > verify.txt

This command will read the contents of the file and verify each file against the SHA 512 hash stored in that file.

shasum -a 512 -c verify.txt
