Not another Command list.
I know, as acronym would require all capital letters, but chemistry calls.
This link brings to an awesome collection of command for Windows, MacOSX, Linux and Oracle (Win the Giant, Mac the Elf, Tux the Dwarf and Orl the Orc).
Precious quote at the bottom of each page, e.g.
"Whom the gods love dies young" - Menander 300 BC after the "kill" command.
I like it very much.
