|
|
remote-update [-d] [-n] [-v] [-y] [-s <sleep seconds>] [-u <update url>]
|
|
|
|
Actions:
|
|
-h Display this help message and exit.
|
|
-c Check for firmware update and exit.
|
|
-w Fetch image and exit, do not perform flash write.
|
|
|
|
Options:
|
|
-d Do not detach from terminal.
|
|
-n Do not backup configuration.
|
|
-v Skip verification of downloaded image.
|
|
-y Assume defaults for all questions.
|
|
|
|
-s <seconds>
|
|
Sleep given amount of seconds before starting flash write.
|
|
If ommitted and '-y' is not used, 5 seconds are assumed.
|
|
|
|
-u <url>
|
|
Fetch firmware image from given url. A file "md5sums" is expected
|
|
in the same remote directory. If there is no such file, use -v to
|
|
suppress verification.
