Hi,

Forgive me for nitpicking but ...

This also finds directories, symbolic links, socket, etc., not just
files. For just files, add `-type f`.
BTW, the pattern passed to -iname is already case insensitive ;-)

Because this suffers from the same as the previous, the -exec {} \; will
fail on matching directories. Use -delete instead.

For clarity's sake, the "somewhere" is in the pathname, not the content
of the pathname.

And, for completeness' sake, the {} is replaced by the pathname that
matched the conditions.

Hope this helps,
