I spent some time looking this up and hopefully I will save someone else time on this. The current work directory for an application in Java is stored in the system property “user.dir”. This is the default directory that you application will write files to if you don’t specify an absolute file location. You can access it using this Java syntax:

String userDir = System.getProperty("user.dir");

I wanted to see the full Maven pom.xml structure and I found the following page on the Maven web site that contains all the elements and descriptions.

http://maven.apache.org/ref/2.2.0/maven-model/maven.html

I had a need to identify what process ID (PID) on my MacBook running OSX that had a specific IP address and port open so that I could kill it. It took me a while to figure this out but eventually I found something that worked.

lsof -i

This will show you

COMMAND     PID     USER        FD   TYPE  DEVICE     SIZE/OFF  NODE  NAME
Microsoft   280     someuser    15u  IPv4  0x8862e64       0t0  TCP   *:3546 (LISTEN)
