Thanks Don. I tried the command but it did not work. Below is the data in my file.There are thousands of lines like this in the original file.But i have taken a few here.
All these lines are having tab spaces in between the fields and some lines are having tab spaces at the end also.
The lines 1,2 and 11,12 are not having tab spaces at the end. The 3,4 lines are having 1 tab space at the end.The 5,6 lines are having 2 tabs paces at the end
and lines 7,8 are having 4 tab spaces at the end and lines 9,10 are having 5 tab spaces at the end.
I want to keep the tab spaces as it is in between fields in all these lines.But I want to remove the tab spaces at the end from the lines 3,4,5,6,7,8,9,10.
for ex:- If i give
Code:
shift$

(command for moving the cursor to the end of the line) in the line 7,then cursor should be highlighting the last digit in the line which is '2'(15172 15172)

Code:
      1 15022	15022	15022	15022	15022	15022
      2 15023	15023	15023	15023	15023	15023
      3 15074	15074	15074	15074	15074	
      4 15075	15075	15075	15075	15075	
      5 15080	15080	15080	15080		
      6 15113	15113	15113	15113		
      7 15172	15172				
      8 15173	15173				
      9 15174					
     10 15175					
     11 15404	15404	15404	15404	15404	15404
     12 15405	15405	15405	15405	15405	15405

Now below is the output which i want.The lines 3,4,5,6,7,8,9,10 should not contain the tab spaces at the end.

Code:
      1 15022	15022	15022	15022	15022	15022
      2 15023	15023	15023	15023	15023	15023
      3 15074	15074	15074	15074	15074
      4 15075	15075	15075	15075	15075
      5 15080	15080	15080	15080
      6 15113	15113	15113	15113
      7 15172	15172
      8 15173	15173
      9 15174
     10 15175
     11 15404	15404	15404	15404	15404	15404
     12 15405	15405	15405	15405	15405	15405

Hope this time i am clear on my need.Kindly suggest me on this.
Thanks in advance.
