Make checksums file usable by common tools

Browse Source 
Adding flag --bsd makes rhash output checksums in a format compatible
with common tools, like sha256sum, and makes it obvious what algorithm a
particular checksum was calculated for, at the expense of making the
checksums file larger. This allows for the checksums file to be used
directly by tools understanding traditional format, like Ansible or
Salt, and  obviates the existence of extract-checksum.sh script.

#!/bin/bash
# This script works with checksums_hashes_order and checksums to extract the relevant
# sha of the various yq downloads. You can then use your favourite checksum tool to validate.
# <CHECKSUM> must match an entry in checksums_hashes_order.
#
# Usage: ./extract-checksum.sh <CHECKSUM> <FILE>
# E.g: ./extract-checksum.sh SHA-256 yq_linux_amd64.tar.gz
# Outputs:
# yq_linux_amd64.tar.gz acebc9d07aa2d0e482969b2c080ee306e8f58efbd6f2d857eefbce6469da1473
#
# Usage with rhash:
# ./extract-checksum.sh SHA-256 yq_linux_amd64.tar.gz | rhash -c -
#
# Tip, if you want the checksum first then the filename (e.g. for the md5sum command)
# then you can pipe the output of this script into awk to switch the fields around:
#
# ./extract-checksum.sh MD5 yq_linux_amd64.tar.gz | awk '{ print $2 " " $1}' | md5sum -c -
#
