Check out if you get the required o/p
I don't need "java_home=" or "weblogic_home=" in the output.

All i need is the output value be assigned to bash variable. Please read OP for details.

Here is another approach:
Code:
#!/bin/bash

o=$( ps -xef | grep <pid> )

for t in $o
do
        [[ $t =~ java ]] && java_home="$t"
        [[ $t =~ -Dplatform.home ]] && weblogic_home="${t#-Dplatform.home=}"

done

Hi,

echo $java_home # does not yeild the correct result
echo $weblogic_home # yeilds the correct result.

From the below output

Code:
     bea 15160 15144  0  Feb 20  ?        52:49 /opt/jdk150_07/bin/IA64N/java -Dplatform.home=/opt/bea/weblogic92 -Dwls.home=/opt/bea/weblogic92/server -Djava.security.policy=

echo $java_home yeilds "-Djava.security.policy=" instead of "/opt/jdk150_07/bin/IA64N/java"

The best string to grep for the correct java could be to grep using keyword "bin" and "/java".
Also, when i copy paste it in my main script, i get the below error.

Code:
 
./master_script.sh[27]: Syntax error at line 78 : `=~' is not expected.

Kindly help.

That is because it assigned the last occurrence of pattern: java

Replace [[ $t =~ java ]] with [[ $t =~ /java ]]

I hope this helps.

It does help.

It works when I create a new script file and copy-paste your code.

But, when i copy paste it in my existing script the same code, i get the below error.

Code:
 
./master_script.sh[27]: Syntax error at line 78 : `=~' is not expected.

I have HP-UX

Kindly help.

OK, then replace existing for loop with:
Code:
for t in $o
do
        if echo "$t" | grep -q "/java"
        then
                java_home="$t"
        fi
        if echo "$t" | grep -q "\-Dplatform\.home"
        then
                weblogic_home="${t#-Dplatform.home=}"
        fi
done

OR
Code:
for t in $o
do
        $( echo "$t" | grep -q "/java" )  && java_home="$t"
        $( echo "$t" | grep -q "\-Dplatform\.home" ) && weblogic_home="${t#-Dplatform.home=}"
done
