rocketsh
The interactive shell used to execute commands and run programs. Launched by init.
The rocketsh shell supports two forms of input; firstly any command you type is searched for as a program under the /programs directory. If it can be found it is executed.
If no matching program can be found, the line is passed to [eval](eval basic code) instead and any changes to the program state will be inherited by rocketsh, e.g. you can type
PROMPT$=">"and this will set the shell prompt to a single > symbol.
