根据command not found， 找到该错误打印来自函数 “msh_exec”。 大家帮我看看这是什么错误？
```c
int msh_exec(char *cmd, rt_size_t length)
{
    int cmd_ret;

/* strim the beginning of command */
    while ((length > 0) && (*cmd  == ' ' || *cmd == '\t'))
    {
        cmd++;
        length--;
    }

if (length == 0)
        return 0;

/* Exec sequence:
     * 1. built-in command
     * 2. module(if enabled)
     */
    if (_msh_exec_cmd(cmd, length, &cmd_ret) == 0)
    {
        return cmd_ret;
    }
