# <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
# 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 | rhash -c -
# ./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 | awk '{ print $2 " " $1}' | md5sum -c -
# ./extract-checksum.sh MD5 yq_linux_amd64.tar.gz | awk '{ print $2 " " $1}' | md5sum -c -
