I have a file in the form:
Code:
title1:
title2:
title3:
title4:

I want to paste the string "name" after title2. That will be:
Code:
title1
title2: name
title3
title4

paste
where can i get the name, is it constant one or else it may be dynamic value ?

I assume that name is a constant one that wont get anywhere from the file.

Code:
 
1. sed 's/^\(title2:\)/\1 name/g' Input_File
2. awk '{if( $0 ~ /^title2:/ ){print $0,"name";}else{print $0;}}' Input_File

Cheers,

Thank you all for your replies.

rangarasan, you are right, "name" is a dynamic value. In fact I have multiple 'title' files and a file with a list of 'names'. My actual code would be to read each line from the 'name' list and insert this after "title2" in each 'title' file.
