Hush script to recurse through file system?

[Gilles]

Hello

I need to check for any unused shared library in the root filesystem
by using pax-utils' scanelf utility. I suspect several libraries to
have been included without actually being used by any application.

I'm using hush as the shell in Buybox 1.16.2, and was wondering if
hush is able to recurse through the file system, call scanelf for each
item, and parse the answer, or if I should use a higher-level
scripting tool.

Thank you.
