GIFDIFF(1)

🦋 GIFDIFF(1) — gifdiff 🦋

okay bestie, welcome to the gifdiff(1) manual page from the General Commands Manual — header energy folded in cute, facts kept intact. 💅

✨ NAME ✨

gifdiff — compares GIF images. that's the whole name line, and honestly? iconic. 🎀

🌸 SYNOPSIS 🌸

gifdiff [options] GIF-file-1 GIF-file-2

💖 DESCRIPTION 💖

okay so gifdiff compares two GIF files and determines if they appear identical. the key word is appear. differences that don't affect appearance — like colormap ordering or how much an animation is optimized — are not reported. fake-out differences, bestie; gifdiff is not here for them. no cap.

like web browsers, gifdiff treats the area outside the first frame, and areas cleared by background disposal, as transparent. it also ignores the GIF's background color. 🫶

gifdiff prints details of any differences it finds. if the GIFs are the same, it prints nothing. silence = slay in this case. ✨

exit status tea:

• 0 — there were no differences.
• 1 — there were some differences.
• 2 — there was trouble.

🔥 OPTIONS 🔥

• --brief, -q — report only whether the GIFs differ, not the details of the differences. short and nosy, but make it brief. 💅
• --ignore-redundancy, -w — do not report differences in the numbers of redundant frames (frames which do not change the displayed image). so if one file has extra do-nothing frames, this flag says “bestie, we're not doing that today.” 💀
• --ignore-background, -B — accepted for compatibility; has no effect. it's literally just there to be polite. 🫶
• --help — print usage information and exit. the classic “what are the vibes” button. 🎀
• --version — print the version number and some quickie warranty information and exit. “quickie warranty information” is such a phrase, iykyk. 😭
