Please wrap all code, files, input and output/errors in CODE tags.
It makes it easier to read and preserves multiple spaces and doesn't wrap lines.

The first line wasadmin 5935 54288 0 12:39 pts/8 00:00:00 grep java
 is NOT a actual process it is a process of the command itself, so if you do the following command it shoult not come then.
Code:
ps -ef | grep -v "grep" | grep java

Now if we want to get output for ccos2104Cell ccos2104 aa then following may help.
Code:
ps -ef | grep -v "grep" | grep "java" | awk '{print $(NF-2) OFS $(NF-1) OFS $NF}'

On a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk , /usr/xpg6/bin/awk , or nawk. Hope this helps.


Thanks,
R. Singh

I'm confused a little. perhaps some good practice will help you whilst I try to work out what you need.

If you change your command to be ps -ef | grep jav[a] then you will only get the header and any real java processes, i.e. your grep will be excluded. If you want just a few columns from that very wide output, consider the -o formatting flag for the command instead, perhaps something like this will meet your needs if you are sure that these is just one real java process:-
Code:
ps -e -o pid= -o comm= | grep jav[a] | read PID COMM


I hope that this helps,
Robin
