linux - How do I run ssh-keygen so that it overwrites without prompting if a key cert exists? -

-

so have scenario remote call made target machine. it's possible more 1 call made generate ssh keys, in case script hang requests overwrite (y/n).

is there proper way request non-interactive overwrite (or silently ignore) of keys if found?

there doesn't seem --force or --overwrite option in 

man ssh-keygen

that can find. there rationale having function way, or bug should report authors?

any appreciated.

you can work around thusly:

echo -e  'y\n'|ssh-keygen -q -t rsa -n "" -f ~/.ssh/id_rsa

it still output prompt, complete process , overwrite file.

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
