Determine if icon is being used

I saw this icon hb-icon.svg in /usr/share/app-install/icons/

And it is 3.4 Mb !!

Why is an icon so big?

Can I tell if it is being used so if it isn't, I can delete that monster?

Probably not safe to delete. It's part of the app-install-data package, which is needed by several other important packages.

walt@bat:~(0)$ ll /usr/share/app-install/icons/hb-icon.svg

If you're at the point where deleting a 3.3M file is starting to look like a Good Idea, you're not solving the right problem - why don't you have enough disk space, and where don't you have it?

According to the search on codesearch.debian.net this icon is related to Handbrake.

Search on packages.ubuntu.com confirms this. So it simply great and pretty icon scalable SVG icon of Handbrake.

Both icons in /usr/share/app-install/icons/hb-icon.svg and /usr/share/icons/hicolor/scalable/apps/hb-icon.svg have identical MD5 sums. So really the icon may be removed from /usr/share/app-install/icons/hb-icon.svg without problems.

But the icon itself looks very nice, elegant and detailed (1658 x 1721 pixels)

The removal will not save much space. So I'll recommend to save it :)
