Hello Patrick,

Let’s talk about ranges a little more. As already mentioned, for most commands, the default range is . (the current line). However, for :g (global) and :w (write) commands the default is % (all lines).

Learning by example is very effective, so here’s a few:

Replacement in the whole file ¶

Let’s say your task is to replace all occurrences of the string with new string in the whole file. This is a very common use case.

Here’s how you do it:

           %s/old_string/new_string/g

          

%s means that substitution will be performed for all the lines.
g specifies that the action will be performed over all occurrences in the line.

If the g flag were not used in the command above, only the first occurrence in the line would be replaced.

Replacement in range: line after current line to end of a file ¶

:.+1,$s/bad/good/g

Replacement in range: current to current+5 line, inclusive ¶

           :.,.+4s/bad/good/g

          

Replacement in range: between patterns a and b, inclusive ¶

:?a?,/b/s/bad/good
