Reported as "sh", ash is my Openmoko phone's default shell.
I found a list of Ash commands on the following page.
http://puppylinux.org/wikka/AshCommands
Using a terminal window via SSH into the phone, I tried each command in
turn as an argument to the "type" command.
Though the following were reported as "not found":
* builtin;
* fc;
* help; and
* setvar.
Most of the rest were reported as being "shell builtins".
However the following were described as "special shell builtins":
* break;
* continue;
* eval;
* exec;
* exit;
* export;
* readonly;
* return;
* set;
* shift;
* times;
* trap; and
* unset.
What is the difference between a shell builtin and a special shell builtin?
