Hi guys!
Me again! ...
I'm trying to build (on MacOS directly) a bash script that will help me verify a SHA1 digest (to verify downloads and so on and so forth).
So first off, here's my version of BASH under OSX:
bash-4.4$
And here's my version of Sierra (macOS):

digest
digest(1) User Commands digest(1)NAME
digest - calculate a message digest
SYNOPSIS
/usr/bin/digest -l | [-v] -a algorithm [file...]
DESCRIPTION
The digest utility calculates the message digest of the given file(s) or stdin using the algorithm specified. If more than one file is
given, each line of output is the digest of a single file.
OPTIONS
The following options are supported:
-a algorithm Specifies the name of the algorithm to use during the encryption or decryption process. See USAGE, Algorithms, for details.
-l Displays list of algorithms available on the system. This list can change depending on the configuration of the crypto-
graphic framework.
-v Verbose output. Includes the algorithm name and filename in the output.
USAGE
Algorithms
These algorithms are provided by the Cryptographic Framework. Each algorithm supported by the command is an alias of the PKCS #11 mechanism
for easier access. For example, sha1 is an alias to CKM_SHA_1.
These aliases are used with the -a option and are case-sensitive.
EXAMPLES
Example 1: Simulating output of the common md5sum program
example$ digest -v -a md5 /usr/bin/vi
md5 (/usr/bin/vi) = e4e3588c5212903847c66d36b1a828a5
Example 2: Digesting a file
To generate the sha1 digest of the file /etc/motd:
example$ digest -a sha1 /etc/motd
