Playstation 5 / PS5 video clip filename to update file creation/modified date

update-ps5-vide-clip-creation-date.sh

#!/usr/bin/env bash

# This is to parse and update the creation date of video clips taken from
#   Playstation5 (PS5). For example filenames such as
#   GameTitle_20240719233528.mp4
#   Transferring this file via USB would not retain the creation/modified date
#   which the below bash code would solve

# https://stackoverflow.com/a/43606356
for filename in *.mp4; do  # use mp4 or webm
	[ -e "$filename" ] || continue
	DATESTRING=${filename#*_}
	DATESTRING=${DATESTRING%.*}
	# https://unix.stackexchange.com/a/659291
	STAMP=$(busybox date -D %Y%m%d%H%M%S -d "$DATESTRING" +'%Y%m%d%H%M.%S')
	# https://askubuntu.com/a/711243
	touch -a -m -t $STAMP "$filename"
	DATEDISPLAY=$(busybox date -D %Y%m%d%H%M%S -d "$DATESTRING" +'%c')
	echo "Updated $filename to have $DATEDISPLAY as creation date"
done
