bash - Unable to escape $0 in awk script within 2 ssh sessions. Works in 1 ssh session -

-

i having trouble getting script run.

the following script works (awk within ssh session):

ssh root@db01 "cat /tmp/$togo  \ |openssl aes-256-cbc -d -salt -pass pass:aaaaaaaaaaaaa \ |gunzip \ |gawk -v envbucket='design.test.bucket' -v prodbucket='design.bucket' '{gsub(prodbucket,envbucket);print \$0}' \ |gawk -v envbucket='data.test.bucket' -v prodbucket='data.bucket' '{gsub(prodbucket,envbucket);print \$0}' \ | mysql -u root -p'secret' appdb"

but when try run exact same thing inside ssh session within ssh session, fails:

ssh root@intermediateserver "ssh root@db02 \"cat /tmp/$togo  \ |openssl aes-256-cbc -d -salt -pass pass:aaaaaaaaaaaaa \ |gunzip \ |gawk -v envbucket='design.test.bucket' -v prodbucket='design.bucket' '{gsub(prodbucket,envbucket);print \$0}' \ |gawk -v envbucket='data.test.bucket' -v prodbucket='data.bucket' '{gsub(prodbucket,envbucket);print \$0}' \ | mysql -u root -p'secret' appdb\""

this script works if remove 2 gawk commands , pipe gunzip output directly mysql. gawk commands in pipeline, output becomes empty.

i assume has print $0 not escaping within double-quotes within double-quotes.

i've been stuck on while i'm hoping here can help.

p.s. aware of security risks associated these script. in current form, being run in test environment.

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
