Try this, it will help you. Open the file in vi editor: 

$ vi /file/location  

:1,100 s/^/DMS/ --> Enter
  • 1,100 is exactly from which line you want to start and end.
  • s is the substitution command and ^ means the the line starting.

Or you can do it without opening the file, using GNU sed:

sed -i 's/^/DMS /' /your/file/location

  • I don't think you *can* do it without opening the file - at least not without directly editing the underlying block device, and probably the filesystem will object to that, anyway - and I'm pretty positive you definitely can't w/ `sed`by asking it to open the file. – mikeserv Aug 02 '15 at 11:07
  • I was not able to modify my question as I was facing some technical problem. The question has been marked as duplicate. But today I have again edited my question. But if I want to add the word at the last of my line, then what could be the solution. @cuonglm Your solution has helped me. – Nainita Aug 03 '15 at 09:31
  • @Nainita: You should raise a new question. – cuonglm Aug 03 '15 at 09:33
