Just for the record, */bin/echo,* */bin/ls* and siblings are normally never
used if you're running GNU Bash as your command shell, because Bash has
those commands built-in.

These commands only exist as independent binaries for when you're running a
shell that doesn't have those commands built-in, like the very
minimal /ash/ shell, once popular on small-memory systems.

Just a FYI... ;-)
