#
#   Shell script for linux, Windows/Cygwin, or MacOS.  Last updated 2020-01-12.
#
#   Converts MOV files from iPhones (with stupid names like IMG_0001.MOV)
#   into files named with the date and time stamp from the video file.
#   (E.g. 20171003_151026.mov)
#
#   Usage: run it in a directory containing .MOV files downloaded from an
#   iPhone. Renames all of them.
#
#   Requires installing the 'exiftool'.  See https://exiftool.org/install.html
