Thanks,

Hi Ravinder, you appear to have left out "Cable " in the output...

It could be shortened a little:
Code:
awk -v s1='Cable Yes && !Pay TV && !ADS' '$0==s1 {$0=$0 " && !MDS"}1' Input_file

Hi All,

Thanks for your time. I have tried all the codes provided by you all. I am getting the same error message

Code:
Pay: Event not found

Ravinder, I have used the exact code given by you. But still the same error.
Also as per Scrutinizer comments, have used single quotes instead of double quotes. Still the same error.

I am working in Ksh shell. I do not have any idea about bash shell

Hello am24,

Could you please try this and let me know if this helps.
Code:
awk '{num=split("Cable Yes && !Pay TV && !ADS", array," ");for(i=1;i<=num;i++){if($0 ~ /^Cable/ && array[i]==$i && $0 ~ /ADS$/){count++}};if(count==NF){$0=$0 " && !MDS"};count=""} 1'   Input_file

Output will be as follows.
Code:
Cable Yes && !Pay TV && !ADS && !MDS
chumma Cable Yes && !Pay TV && !ADS xycc
\noUE  \Label="Cable Yes && !Pay TV && !ADS"

As always on a Solaris/SunOS system, change awkto /usr/xpg4/bin/awk , /usr/xpg6/bin/awk , or nawk.
EDIT: Improving above solution as follows.
Code:
awk '{num=split("Cable Yes && !Pay TV && !ADS", array," ");for(i=1;i<=num;i++){if(array[i]==$i){count++}};if(count==NF){$0=$0 " && !MDS"};count=""} 1'  Input_file

Thanks,
R. Singh

Hi Ravinder,

I had tried the code. But same below error:

Code:
nawk '{num=split("Cable Yes && !Pay TV && !ADS", array," ");for(i=1;i<=num;i++){if(array[i]==$i){count++}};if(count==NF){$0=$0 " && !MDS"};count=""} 1'  Input_file
Pay: Event not found

Scrutinizer, I have tried your code as well. But same error message.

I am trying to do it. But not getting the results. If anyone find the solution please post.

Regards,
am24

Are you sure that's a ksh error message? It strongly reminds me of an unsuccessful bash history search...
The proposals in post#3 (hopefully) don't interfere with history expansion...

Code:
Pay: Event not found

What output do you get from the command:
Code:
ps -t $(tty)
