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):

sha1sum
SHA1SUM(1) User Commands SHA1SUM(1)NAME
sha1sum - compute and check SHA1 message digest
SYNOPSIS
sha1sum [OPTION]... [FILE]...
DESCRIPTION
Print or check SHA1 (160-bit) checksums.
With no FILE, or when FILE is -, read standard input.
-b, --binary
read in binary mode
-c, --check
read SHA1 sums from the FILEs and check them
--tag create a BSD-style checksum
-t, --text
read in text mode (default)
The following five options are useful only when verifying checksums:
--ignore-missing
don't fail or report status for missing files
--quiet
don't print OK for each successfully verified file
--status
don't output anything, status code shows success
--strict
exit non-zero for improperly formatted checksum lines
-w, --warn
warn about improperly formatted checksum lines
--help display this help and exit
--version
output version information and exit
The sums are computed as described in FIPS-180-1. When checking, the input should be a former output of this program. The default mode is
to print a line with checksum, a space, a character indicating input mode ('*' for binary, ' ' for text or where binary is insignificant),
and name for each FILE.
BUGS
Do not use the SHA-1 algorithm for security related purposes. Instead, use an SHA-2 algorithm, implemented in the programs sha224sum(1),
sha256sum(1), sha384sum(1), sha512sum(1), or the BLAKE2 algorithm, implemented in b2sum(1)AUTHOR
