% &, and
% d commands flag many files for deletion, based on their file names:
Flag all auto-save files (files whose names start and end with ‘
#’) for deletion (see Auto Save).
Flag all backup files (files whose names end with ‘
~’) for deletion (see Backup).
Flag excess numeric backup files for deletion. The oldest and newest few backup files of any one file are exempt; the middle ones are flagged.
Flag for deletion all files with certain kinds of names which suggest you could easily create those files again.
% d regexp RET
Flag for deletion all files whose names match the regular expression
dired-flag-auto-save-files) flags all files whose names look like auto-save files—that is, files whose names begin and end with ‘
#’. See Auto Save.
dired-flag-backup-files) flags all files whose names say they are backup files—that is, files whose names end in ‘
~’. See Backup.
dired-clean-directory) flags just some of the backup files for deletion: all but the oldest few and newest few backups of any one file. Normally, the number of newest versions kept for each file is given by the variable
kept-new-versions; that applies only when saving). The number of oldest versions to keep is given by the variable
Period with a positive numeric argument, as in
C-u 3 ., specifies the number of newest versions to keep, overriding
dired-kept-versions. A negative numeric argument overrides
kept-old-versions, using minus the value of the argument to specify the number of oldest versions of each file to keep.
% & (
dired-flag-garbage-files) flags files whose names match the regular expression specified by the variable
dired-garbage-files-regexp. By default, this matches certain files produced by TeX, ‘
.bak’ files, and the ‘
.orig’ and ‘
.rej’ files produced by
% d flags all files whose names match a specified regular expression (
dired-flag-files-regexp). Only the non-directory part of the file name is used in matching. You can use ‘
^’ and ‘
$’ to anchor matches. You can exclude certain subdirectories from marking by hiding them while you use
% d. See Hiding Subdirectories.
