vim search and replace using current line as reference point

Question

Is there a way to specify search and replace range using the current line as a reference? I can specify range using explicit line numbers like

:5,15s/foo/bar/g
<         


        

Answer 1

You can use . for the current position, and .+10 for 10 lines down:

:.,.+10s/foo/bar/g

Some other useful ranges:

• % for the whole file.
• '<,'> for the lines of visually selected block. This might get you more than you want of the visual selection starts or ends in the middle of a line. The whole line is included.
• 'a,'b from mark a to mark b.
• .,$ from the current line to the end of the file.
