The Bootable CD comes with some shell utilities written over the years to make shell programming a bit easier for common items. Some of these are described here.

| count | count [to] | [from to [by]] |
| digits | get some digits |
| dollars | get some dollars (and optional cents) |
| IPaddr | get an IP address |
