The utility programs in root. q, Esc or Ctrl-C exits nearly all of them, and 'name see shows the source of any of them. Games and demos cover the rest.

Everyday

clock, stopwatch (space marks a lap) and 90 timer (in seconds). In QEMU the clock shows UTC unless configured otherwise (QEMU).

todo, with "buy milk" todo-add and 1 todo-done. The list is a definition called todo-list in your tab, so each tab has its own, back undoes changes to it, and it is saved with the world.

calc is an infix calculator with + - * / % ** ( ) & | ^ ~ << >>, 0x and 0b literals, six decimal places and ans for the previous result. An empty line exits.

255 bases prints a number in decimal, hex, octal and binary. convert lists the unit conversions such as 100 km>mi. password prints random passwords, and 12 password-of makes one of a given length. ascii and colors print reference tables.

Monitoring

top shows the tabs, CPU, memory and interrupts live. [ ticks . ] watch reruns a quote twice a second until a key is pressed, and timeit times one run. bench is described with the JIT.

Hardware

sys, pcils, memls, cpuinfo and irqmon only read, so they are safe to run.

hexview is not. 0xB8000 hexview opens a hex editor on live memory, and typing hex digits writes directly to RAM with no undo. It is built on the memory words.

disks and install are described in installation.
