Command Line – How to Find, Kill, and Restart Local DynamoDB Process

command line

I'm working with Amazon's DynamoDB and I can't figure out how to programmatically kill the process reliably by name or PID.

I need to restart it since I'm holding all data in memory and I can delete the entire thing by just easily restarting the process. Problem is I can't figure out how to kill it as easily as starting it.

ps -ax | grep "Dynamo" returns 19355 ttys001 0:28.31 /usr/bin/java -Djava.library.path=./DynamoDBLocal_lib -jar /Users/user/workspace/lib/DynamoDBLocal.jar -sharedDb -port 8000 -inMemory

But when I try killall DynamoDBLocal.jar I receive No matching processes belonging to you were found and the PID changes every time it's started up.

How can I programmatically find the PID to send to kill -9 PID or properly killall by name?

EDIT: Finished! Here's my work to share with others:

alias start_dynamo='java -Djava.library.path=./DynamoDBLocal_lib -jar /Users/user/workspace/lib/DynamoDBLocal.jar -sharedDb -port 8000 -inMemory &'

alias end_dynamo="kill `ps -ax | grep Dynamo | grep -v grep | awk '{print $1}'`"

alias restart_dynamo='end_dynamo; start_dynamo'

Best Answer

kill `ps -ax |grep Dynamo |awk '{print $1}'`

should do it. note, this will kill any proc that matches Dynamo
