It replaces all words in the last columns of all lines when there is no word "table_name" in those lines.

How about this... :%s/^.* /&test_/g

misread the requirement - your sample data could have been a bit more representative/variable to illustrate the requirement. Try this:
Code:
%s/table_name/test_table_name/2

Thanks, same issue. It replaces all words in the last columns on all lines (irrespective of whether there is the word "table_name" in those lines).

Yeah, that's what all links on google say should work, but it just doesn't work for me. Maybe it is my VI editor issue. Smilie

this will attach 'test_' to the LAST column regardless of its value.
The OP want to prefix 'test_' to second occurrence of 'table_name' ONLY to its SECOND occurrence - it can be a 3 column or the LAST column...
The sample file was not really representative of the requirement.

In your sample you show that every line contains exactly two occurrences of table_name in each line in your file. Is that true in the file you're editing?

Could some lines have zero or only one occurrence of table_name?

Could any lines have three or more occurrences of table_name?
