Weird, the ps command allows you to monitor the status of all active processes, both foreground and background.
For example, I start the following process in a first shell:
Security manager installed using the Basic server security policy.
Apache Derby Network Server - 10.3.2.1 - (599110) started and ready to accept connections on port 1527 at 2010-06-18 14:14:33.277 GMT
And in another shell:
$ ps aux | grep NetworkServer | grep -v grep
pascal 5928 0.3 1.4 661492 29216 pts/0 Sl+ 16:14 0:03 /usr/lib/jvm/java-6-sun/bin/java -classpath /usr/share/javadb/lib/derby.jar:/usr/share/javadb/lib/derbynet.jar:/usr/share/javadb/lib/derbytools.jar:/usr/share/javadb/lib/derbyclient.jar org.apache.derby.drda.NetworkServerControl start
The process is listed as expected (and the
+ shows that it is in the foreground process group).
