Hi Ravinder,

I have run the code using nawk and got the below output.


Code:
          Cable Yes & Pay \exclusive
               Cable Yes && Pay TV && DBS                                                \noUE
               Cable Yes && Pay TV && (Satellite Dish || Master Antenna)        \noUE  \Label="Cable Yes && Pay TV && Other ADS"
Cable Yes && Pay TV && !ADS && !MDS \noUE
          Cable Yes & No Pay \exclusive

The string is getting replaced but the space issue was there.

Thanks & Regards,

Alos the set -x option is included in the script final.sh . when i am executing it its not diplaying set -x but if i do cat final.sh then set -x can be seen.

I would like to mention below points:

I have tried the code by keeping the code in final.sh (as ascript). When i did not used nawk (means when i am using awk ), i got the the awk error lines which i posted in earlier post. Also the file did not modified.

When i used nawk (with set -x and without set -x ) in the script, the file got modified.but again the space issue was there.

am24
