java-info

A bash script for OS X that details information about java on the machine

More details about the script can be found here: http://cs.lth.se/peter-moller/script/java-info-en/

Overview of the script:

/usr/libexec/java_home is the base for the script. This reports all java instances that the system knows about.

Java web browser plugin is reported separately.

If there are any running java-instances, the following is reported for each process:

• $USER and $PID
• Command that is running
• Java version for that command
• What application/process launched it, $PPID and who is running it?

Finaly, information is presented on:

• Where you can download Java 6 [from Apple]
• Where you can download the latest Java-release [from Oracle]
• How you test if Java works in the web browser

The script deals with spaces in PATH of a running command (was a bit tricky :-)

Assumptions:

• Any running java binary is assumed to be named java
• That “ -” (space followed by a dash) is the start of the arguments on the process listing and not part of the PATH of the running application or java instance
