	# A simple shell script to delete a media from Apache's mod_disk_cache.
	# You will likely need to setup a sudo rule like the following:
	#
	# Cmnd_Alias HTCACHECLEAN = /usr/local/sbin/htcacheclean
	# pleroma ALL=HTCACHECLEAN, NOPASSWD: HTCACHECLEAN
	#
	# Please also ensure you have enabled:
	#
	# config :pleroma, Pleroma.Web.MediaProxy.Invalidation.Script, url_format: :htcacheclean
	#
	# which will correctly format the URLs passed to this script for the htcacheclean utility.
	#

	SCRIPTNAME=${0##*/}

	# mod_disk_cache directory
	CACHE_DIRECTORY="/tmp/pleroma-media-cache"

	## Removes an item via the htcacheclean utility
	## $1 - the filename, can be a pattern .
	## $2 - the cache directory.
	purge_item() {
	sudo htcacheclean -v -p "${2}" "${1}"
	} # purge_item

	purge() {
	for url in $@
	do
	echo "$SCRIPTNAME delete \`$url\` from cache ($CACHE_DIRECTORY)"
	purge_item "$url" $CACHE_DIRECTORY
	done

	purge $@
