[[name-by-date.sh]] is a [[bash]] script to rename JPEGs to show their
creation date.

    $ name-by-date.sh *.JPG

    DSC_0356.JPG taken on "2010.07.02.08.38.10"
    ...

`name-by-date.sh` uses the `exif` command line interface to
[libexif][] to extract the date from the picture's metadata, so you'll
have to install that first.
