I just came across this example in Learning the vi and Vim Editors:

.Rh 0 "Get status of named file" "STAT"

The explanation given is: First, ex finds and marks each line that matches the first pattern. Second, for each marked line, it sets . (dot, the current line) to that line and executes the command.

But why do we need the dot after /SYNTAX/? Is it a special syntax for the g command?


:g takes a command after its pattern. :m is the command, and it takes a range before it. . is the beginning of that range.

  • I see, so :g will automatically set . to the line that matches the pattern? – Yang Jun 29 '13 at 5:22
