Set the 'exit on error control' and/or 'print a trace' of commands when parsing scripts in NSH. The settinngs are in effect from the point of exection, until they are changed again, or in the case of the init script, the settings are returned to the default settings when it exits. Included child scripts will run with the parents settings and changes made in the child script will effect the parent on return. Use 'set -e' to enable and 'set +e' to disable (ignore) the exit condition on commands. The default is -e. Errors cause script to exit. Use 'set -x' to enable and 'set +x' to disable (silence) printing a trace of the script commands as they are ececuted. The default is +x. No printing of a trace of script commands as they are executed.

* Name: nsh_consolemain (Normal character device version)
|
|
*
|
|
* Description:
|
|
* This interfaces may be to called or started with task_start to start a
|
|
* single an NSH instance that operates on stdin and stdout. This
|
|
* function does not normally return (see below).
|
|
*
|
|
* This version of nsh_consolmain handles generic /dev/console character
|
|
* devices (see nsh_usbconsole.c and usb_usbkeyboard for other versions
|
|
* for special USB console devices).
|
|
*
|
|
* Input Parameters:
|
|
* Standard task start-up arguments. These are not used. argc may be
|
|
* zero and argv may be NULL.
|
|
*
|
|
* Returned Values:
|
|
* This function does not normally return. exit() is usually called to
|
|
* terminate the NSH session. This function will return in the event of
|
|
* an error. In that case, a non-zero value is returned (EXIT_FAILURE=1).
