exiftool

exiftool is pretty awesome!

Installation

On Linux:

sudo apt install exiftool

On MacOS:

Use

Here are commands I found useful:

Test renaming image files by date:

exiftool -d '%Y-%m-%d' '-Testname<${DateTimeOriginal}.${FileSequence;$_=sprintf("%03d", $_ )}.%le' *.*

And then to actually rename the files:

exiftool -d '%Y-%m-%d' '-Filename<${DateTimeOriginal}.${FileSequence;$_=sprintf("%03d", $_ )}.%le' *.*

To strip EXIF metadata from the image:

exiftool -all= foo.jpg

Alternatively, to remove geographical coordinates embedded in the photo:

exiftool -geotag= foo.jpg
