'Whereis' output

Is there a way to make the 'whereis' command show a more detailed listing, so you know which results are files and which are folders?

Wow, that is cool!

So you put those terms in parentheses () ... I've never them used in a command like that. How does it work?

The $(program) or its synonym `program` ( ` - backquote, not ') are expanded by the shell to the output of "program". For example:

whereis bash
bash: /bin/bash /usr/share/man/man1/bash.1.bz2

so "ls -l $(whereis bash)" is translated by the shell to

ls -l bash: /bin/bash /usr/share/man/man1/bash.1.bz2

You may have noticed the first row of the output:
ls: bash:: No such file or directory
