I am new to Tiny Core.  Loaded CorePlus-current.iso into 349M of RAM on an old Dell Inspiron 2600 laptop using "plop boot manager" and a USB drive (CDROM does not work properly).  Tiny Core was the only distribution that would come up and work at all.
Using App->Cloud->Browse->Download Only of "util-linux" Status shows it completed OK.
Tried to use "whereis" but it was not present.    Depends tabs shows it is supposed to be in /usr/local/bin/.  
It is not there.  What am I doing incorrectly?
