Hello Team,

bash-3.00$ ps -eo pid,pcpu,args | sort +1n | grep -i java
3385 0.0 grep -i java
8804 0.0 /opt/app/ccr/home/ccr/WebSphere/AppServer/java/bin/sparcv9/java -XX:+UnlockDiag
9241 0.0 /opt/app/ccr/home/ccr/WebSphere/AppServer/java/bin/sparcv9/java -XX:+UnlockDiag
18558 0.0 /opt/app/ccr/home/ccr/WebSphere/AppServer/java/bin/java -Xms128m -Xmx512m -DPOL
26719 0.0 /usr/jdk1.6.0_18/bin/java -Djava.compiler=NONE -Djava.security.auth.login.confi

FREEMIND(1)						      General Commands Manual						       FREEMIND(1)

NAME
freemind -- A Java program for creating and viewing mindmaps. SYNOPSIS
freemind [no_options] DESCRIPTION
This manual page documents briefly the freemind command. This manual page was written for the Debian distribution because the original program does not have a manual page. Instead, it has docu- mentation as a mindmap (see Help menu in FreeMind). freemind is a program that allows to create and view so-called mindmaps, as well as export them to HTML or different image formats. It also has a plugin concept to extend its functionality. OPTIONS
This program does not have any option. Just start it! ENVIRONMENT VARIABLES
DEBUG If this environment variable is set, freemind gives more information on how it finds its different elements, as well as some other information. JAVACMD Default value for the java virtual machine (the java command). JAVA_BINDIR If $JAVACMD is not set, the java virtual machine is searched under $JAVA_BINDIR/java. JAVA_HOME If $JAVACMD and $JAVA_BINDIR are not set, the java virtual machine is searched under $JAVA_HOME/bin/java. PATH If all $JAVA... environment variables fail, the java virtual machine command (java) is searched in the $PATH (with which). CLASSPATH ADD_JARS The $CLASSPATH variable also lets one specify additional jars, which is good, if you want to add a new Look&Feel jar (the motif one is so ugly...). Alternatively, the content of $ADD_JARS will be prepended to $CLASSPATH. FREEMIND_BASE_DIR Directory where FreeMind searches for its plugins and libraries FILES
/etc/freemind/freemindrc ~/.freemind/freemindrc freemind tries to read its environment variables from /etc/freemind/freemindrc and ~/.freemind/freemindrc, so that specific set- tings are possible at machine and user level. /usr/bin/java If all searches through environment variables fail, the java virtual machine is expected to be /usr/bin/java; if not, freemind exits with an error.
