@section Subdirectory Switches in Dired
|
||
|
|
|
||
|
|
You can insert subdirectories with specified @code{ls} switches in
|
||
|
|
Dired buffers, using @kbd{C-u i}. You can change the @code{ls}
|
||
|
|
switches of an already inserted subdirectory using @kbd{C-u l}.
|
||
|
|
|
||
|
|
In Emacs versions 22.1 and later, Dired remembers the switches, so
|
||
|
|
that reverting the buffer will not change them back to the main
|
||
|
|
directory's switches. Deleting a subdirectory forgets about its
|
||
|
|
switches.
|
||
|
|
|
||
|
|
Using @code{dired-undo} (usually bound to @kbd{C-_} and @kbd{C-x u})
|
||
|
|
to reinsert or delete subdirectories, that were inserted with explicit
|
||
|
|
switches, can bypass Dired's machinery for remembering (or forgetting)
|
||
|
|
switches. Deleting a subdirectory using @code{dired-undo} does not
|
||
|
|
forget its switches. When later reinserted using @kbd{i}, it will be
|
||
|
|
reinserted using its old switches. Using @code{dired-undo} to
|
||
|
|
reinsert a subdirectory that was deleted using the regular
|
||
|
|
Dired commands (not @code{dired-undo}) will originally insert it with
|
||
|
|
its old switches. However, reverting the buffer will relist it using
|
||
|
|
the buffer's default switches. If any of this yields problems, you
|
||
|
|
can easily correct the situation using @kbd{C-u i} or @kbd{C-u l}.
|
||
|
|
|
||
|
|
Dired does not remember the @code{R} switch. Inserting a subdirectory
|
||
|
|
with switches that include the @code{R} switch is equivalent with
|
||
|
|
inserting each of its subdirectories using all remaining switches.
|
||
|
|
For instance, updating or killing a subdirectory that was inserted
|
||
|
|
with the @code{R} switch will not update or kill its subdirectories.
|
||
|
|
|
||
|
|
The buffer's default switches do not affect subdirectories that were
|
||
|
|
inserted using explicitly specified switches. In particular,
|
||
|
|
commands such as @kbd{s}, that change the buffer's switches do not
|
||
|
|
affect such subdirectories. (They do affect subdirectories without
|
||
|
|
explicitly assigned switches, however.)
|
||
|
|
|
||
|
|
You can make Dired forget about all subdirectory switches and relist
|
||
|
|
all subdirectories with the buffer's default switches using
|
||
|
|
@kbd{M-x dired-reset-subdir-switches}. This also reverts the Dired buffer.
