void shell_cmd_XXX(int argc, char *argv[])
{
    shell_puts("hello world!\n\r");
}
 
HOOK_SHELL_CMD(XXX);

Next, append the new source file to the tenok/shell/shell.mk:

...
SRC += $(PROJ_ROOT)/user/shell/XXX.c

Now, recompile the source code:

cd tenok/
make

Finally, you should able to run your new shell command in the system:

USER@stm32f407:/$ XXX
hello world!
