Specify recursion maximum depth level @var{depth} (@pxref{Recursive
Download}).
Set the maximum number of subdirectories that Wget will recurse into to @var{depth}.
In order to prevent one from accidentally downloading very large websites when using recursion
this is limited to a depth of 5 by default, i.e., it will traverse at most 5 directories deep
starting from the provided URL.
Set @samp{-l 0} or @samp{-l inf} for infinite recursion depth.
@example
wget -r -l 0 http://@var{site}/1.html
@end example
Ideally, one would expect this to download just @file{1.html}.
but unfortunately this is not the case, because @samp{-l 0} is equivalent to
@samp{-l inf}---that is, infinite recursion. To download a single @sc{html}
page (or a handful of them), specify them all on the command line and leave away @samp{-r}
and @samp{-l}. To download the essential items to view a single @sc{html} page, see @samp{page requisites}.
