hi anbu,

i implemented your code. i just did a small change. i changed 'awk' to 'nawk' because its solaris OS. I didnt get the output when i used 'awk'.

the output of my code is as follows
Code:
CP_NUM_RUN_: 3
CP_MAX_TASK: 20
CP_NUM_RUN_:
CP_MAX_TASK:
CP_NUM_RUN_:
CP_MAX_TASK:

I want my output to be like this
Code:
CP_NUM_RUN_: 3
CP_MAX_TASK: 20

I did a set -x and i got the following

Code:
+ nawk -v var1=CP_NUM_RUN_ -v var2=CP_MAX_TASK
$0 ~ var1 {
flag=1
ind1=index($0,var1);ind2=index($0,var2);
for(i=1;i<=NF;++i)
{
        if( $i == var1 ) fld1=i;
        if( $i == var2 ) fld2=i;
}
getline
len1=length($fld1)
len2=length($fld2)
getline
}
flag == 1 {
print var1 ": " substr($0,ind1,len1) "\n" var2 ": " substr($0,ind2,len2)
}
CP_NUM_RUN_: 3
CP_MAX_TASK: 20
CP_NUM_RUN_:
CP_MAX_TASK:
CP_NUM_RUN_:
CP_MAX_TASK:
+ exit

I appreciate your help very much. pls help me with it.
