Fixes the date from exported photos. (Sets the file-system date to the recording date from exif data)

fixDate.sh

#!/bin/bash
# Run in folder containing the pictures

for file in *
do
    if [[ $(file --mime-type -b "${file}") == image/* ]]
    then
        touch -t "$(exiftool -createdate $file | awk -F ':| +' '{ print $5$6$7$8$9"."$10 }')" $file;
    fi
done

To use when exporting files with macOS' "Photos".

Or here as one-line command (run in directory containing the pictures):

for file in *; do if [[ $(file --mime-type -b "${file}") == image/* ]]; then touch -t "$(exiftool -createdate $file | awk -F ':| +' '{ print $5$6$7$8$9"."$10 }')" $file; fi done
