whereis: add page

[awaitlink]

Add whereis command page.

I would also provide an example without any switch, like man ls, because it is IMHO the most commonly used form.

Looks ok to me! Can't figure out how to approve it in octodroid, so this comment will have to do ☺️

Somehow -s doesn't seem to work on my system. It works without it.

20:49:51-agniva-~/play/tldr-bot$whereis -s gcc -m git
gcc:
git: /usr/share/man/man1/git.1.gz
20:50:04-agniva-~/play/tldr-bot$whereis -s gcc 
gcc:
20:50:09-agniva-~/play/tldr-bot$whereis gcc 
gcc: /usr/bin/gcc /usr/lib/gcc /home/linuxbrew/.linuxbrew/bin/gcc /usr/share/man/man1/gcc.1.gz

Any idea why ?

The reason is very simple. You don't have source of gcc on your system. Without the switches it searches for binary, source, and manual page files and therefore looks fine because you have the binary and man pages present for gcc.

Ah I see. I thought that /usr/lib/gcc was the source. My bad, should have checked.
