sed command to replace multiple column in one go
Hi,

I want to replace the value in more than one column.
For one column ,following command is working -
Code:
sed 's/./$value_to_replace/$column number' file_name

Code:
e.g. suppose this is input 1111000000
command - sed 's/./M/5'
output= 1111M000000

For two column also command is like -
Code:
 cat file_name | sed 's/./M/5 | sed 's/./M/6'

But if I want to replace n value how to do that?

Thanks...

Hello Preeti Chandra,

There are 2 things here.
I- Please DO NOT use cat Input_file | sed ...... as sed ....... Input_file, it can read Input_file by itself.
II- To substitute all the occurrences of a string you should use sed 's/old_text/new_text/g with single sed only.

Just try it out and let us know how it goes then.

Thanks,
R. Singh

My question is entirely different.
Code:
Input-sequence of binary number(it a file contains multiple values)
from this sequence I want to change some particular column for each input

I have to change some value in the input after that this substitute command .
But above two commands are working fine but I want to change 10 columns in one input ,how to do that??

Hello Preeti,

I think whatever was asked in your post I had tried to answer it, Without letting us know what is sample Input_file and expected output with all conditions by which you want to get the expected result how we could help you? Kindly do help us by providing all details to help you.

Thanks,

Hello Preeti,

Not much clear, suspecting that you need to substitute string 011011111 to 011011111MMMMMMMMMM then following may help you in same.
Code:
sed 's/011011111/011011111MMMMMMMMMM/g'  Input_file

Thanks,
R. Singh
