 # Example command for checking how long a Java process was running (etime = elapsed time)
 ps -eo pid,comm,cmd,start,etime | grep java

 # It will return something like:
 # 21443 java            /opt/jdk8/bin/java -Djava.u   Feb 25  3-12:46:12
 # and this means an uptime of 3 Days, 12 Hours, 46 Minutes and 12 Seconds
