jtv - bash-fu for top cpu consuming threads in jvm along with the output from jstack

So if you ever find yourself needing to find out what threads in a JVM are taking up lots of CPU you can run this little bash script.  It is super stupid and ugly but it gets the job done!

Skip host key checking with ssh and scope

Just a reminder cause I can't remember syntax for the life of me!

ssh -o StrictHostKeychecking=no -o UserKnownHostsFile=/dev/null

Get number of threads in a *nix process

Just so I don't forget this:

ps -L -o pid= -p  | wc -l

on OSX(also works on linux I believe)

NUM=`ps M  | wc -l | xargs` && expr $NUM - 1
