Hello Rajib Podder,

To thank any person in forums, you could HIT THANKS button at left corner of each post. Also please use CODE TAGS for your shown sample Inputs. Could you please try following and let me know if this helps you.

awk '/peter.*@king/{sub("peter","sham")} 1'  Input_file

Output will be as follows.

myself is sham.r1@king
myself is sham.r2@king
myself is sham.r3@king
myself is peter.r4

Thanks,

Hello Rajib Podder,

You could try following sed command too for same.

sed  '/peter.*@king/s/peter/sham/g'

Hi Ravi,

It is working perfectly now.One more question,can we add multiple condition and multiple replacement on same command.

Regards,
Rajib

Yes, we could do multiple conditions in a single command. If you have questions feel free to ask(if different may be in a new thread), request you to take sometime to write your post and use CODE TAGS(see my post how commands are different than text that is because of code tags). Let me know if you have any queries.

Thanks,
R. Singh
