Utility for doing an AUSST sync run with actual diff output

ausst_sync_diff.sh

#!/bin/sh
#
# Dumb script to output an actual diff of a run of Adobe's AUSST software update mirror tool,
# which provides no helpful summary of what changed in its last sync operation. It also runs
# the command with `time`.
#
# Requires the 'tree' command, available from your favourite package manager:
#
# Homebrew: https://github.com/Homebrew/homebrew-core/blob/master/Formula/tree.rb
# pkgsrc: https://github.com/joyent/pkgsrc/tree/trunk/sysutils/tree
# Rudix: http://rudix.org/packages/tree.html
# MacPorts: https://trac.macports.org/browser/trunk/dports/sysutils/tree/Portfile

declare -r ausst_root="/path/to/ausst/root"
declare -r ausst_bin=/path/to/your/AdobeUpdateServerSetupTool

tree_before=$(mktemp)
tree_after=$(mktemp)

tree "${ausst_root}" > "${tree_before}"

time "${ausst_bin}" --root="${ausst_root}" --incremental
tree "${ausst_root}" > "${tree_after}"

echo "Outputting diff from directories before: ${tree_before} to after: ${tree_after}"
diff "${tree_before}" "${tree_after}"
