analogist / gce_md5convert.sh

Last active April 26, 2022 06:45

Convert Google Cloud Storage gsutil ls -L base64-encoded md5 hash listings to md5sum-compatible hash format

	#!/bin/bash
	# This awk/sed script looks for "gs://bucket/path/filename" and "Hash (md5)",
	# swaps the two (so the hash appears before the file, in the md5sum format),
	# cuts out the "gs://bucket/" name, and finally converts the md5 hash
	# from base64 to hex. This allows for later off-line file integrity check
	# via the standard "md5sum -c".
	#
	# To use it, either save it as an alias or a shell script, and pipe the
	# output of gsutil ls -L through it. For example, save it as "md5convert.sh"
	# and then run "gsutil ls -L gs://bucket/path \| bash md5convert.sh"
