- cat (Unix) (Wikipedia)
cat is a standard Unix utility that reads files sequentially, writing them to standard output. The name is derived from its function to (con)catenate files (from Latin catenare, “to chain”). It has been ported to a number of operating systems. ¶ The other primary purpose of cat, aside from concatenation, is file printing — allowing the computer user to view the contents of a file. Printing is the most common use of cat.
And the gold of that land is good: there is bdellium and the onyx stone.

- Onyx (Wikipedia)
Onyx is the parallel-banded variety of chalcedony, a silicate mineral. Agate and onyx are both varieties of layered chalcedony that differ only in the form of the bands. Onyx has parallel bands, while agate has curved bands. The colors of its bands range from black to almost every color. Specimens of onyx commonly contain bands of black or white or both. Onyx, as a descriptive term, has also been applied to parallel-banded varieties of alabaster, marble, calcite, obsidian, and opal, and misleadingly to materials with contorted banding, such as “cave onyx” and “Mexican onyx”.
