# 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 -
|
|
#
