@ -736,6 +736,11 @@ The "!!" command filters the current line through a filter. In Unix the "date"
command prints the current time and date. "!!date<Enter>" replaces the current
line with the output of "date". This is useful to add a timestamp to a file.
Note: There is a difference between "!cmd" (e.g. using it without any file
range) and "{range}!cmd". While the former will simply execute the external
command and Vim will show the output, the latter will filter {range}lines
through the filter and replace that range by the result of the filter command.
See |:!| and |:range!| for details.
