 # <CHECKSUM> must match an entry in checksums_hashes_order.

-# E.g: ./extract-checksum.sh SHA-256 yq_linux_amd64.tar
+# E.g: ./extract-checksum.sh SHA-256 yq_linux_amd64.tar.gz

 # 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 -
