One-liner command

Inspired by this article, use this one-liner command:

$ identify drop_caches.gif | wc -l
128

For more details use:

identify -verbose filename.gif

This website lets you upload your .gif and analyzes it many ways including the number of frames in it:

ezgif.png


The convert provided by Image Magic will convert your .gif into individual .png images one for each frame:

$ convert -verbose -coalesce drop_caches.gif drop_caches.png
