exiv2

Image metadata manipulation tool. More information: https://www.exiv2.org/manpage.html.

• Print a summary of the image Exif metadata:
  exiv2 {{path/to/file}}
• Print all metadata (Exif, IPTC, XMP) with interpreted values:
  exiv2 -P kt {{path/to/file}}
• Print all metadata with raw values:
  exiv2 -P kv {{path/to/file}}
• Delete all metadata from an image:
  exiv2 -d a {{path/to/file}}
• Delete all metadata, preserving the file timestamp:
  exiv2 -d a -k {{path/to/file}}
• Rename the file, prepending the date and time from metadata (not from the file timestamp):
  exiv2 -r {{'%Y%m%d_%H%M%S_:basename:'}} {{path/to/file}}
