value of this variable specifies the sort criteria and sort or-
der for the results of pathname expansion. If this variable is
unset or set to the null string, pathname expansion uses the
- historical behavior of sorting by name. If set, a valid value
- begins with an optional _\b+, which is ignored, or _\b-, which re-
- verses the sort order from ascending to descending, followed by
- a sort specifier. The valid sort specifiers are _\bn_\ba_\bm_\be, _\bs_\bi_\bz_\be,
- _\bm_\bt_\bi_\bm_\be, _\ba_\bt_\bi_\bm_\be, _\bc_\bt_\bi_\bm_\be, and _\bb_\bl_\bo_\bc_\bk_\bs, which sort the files on name,
- file size, modification time, access time, inode change time,
- and number of blocks, respectively. For example, a value of
- _\b-_\bm_\bt_\bi_\bm_\be sorts the results in descending order by modification
- time (newest first). A sort specifier of _\bn_\bo_\bs_\bo_\br_\bt disables sort-
- ing completely; the results are returned in the order they are
- read from the file system, and any leading _\b+ or _\b- is ignored.
- If the sort specifier is missing, it defaults to _\bn_\ba_\bm_\be, so a
- value of _\b+ is equivalent to the null string, and a value of _\b-
- sorts by name in descending order. Any invalid value restores

A colon-separated list of values controlling how commands are saved on
behavior of sorting by name. If set, a valid value begins with an
optional ‘+’, which is ignored, or ‘-’, which reverses the sort
order from ascending to descending, followed by a sort specifier.
- The valid sort specifiers are ‘name’, ‘size’, ‘mtime’, ‘atime’,
- ‘ctime’, and ‘blocks’, which sort the files on name, file size,
- modification time, access time, inode change time, and number of
- blocks, respectively.
+ The valid sort specifiers are ‘name’, ‘numeric’, ‘size’, ‘mtime’,
+ ‘atime’, ‘ctime’, and ‘blocks’, which sort the files on name, names
+ in numeric rather than lexicographic order, file size, modification
+ time, access time, inode change time, and number of blocks,
+ respectively. If any of the non-name keys compare as equal (e.g.,
+ if two files are the same size), sorting uses the name as a
+ secondary sort key.
For example, a value of ‘-mtime’ sorts the results in descending
order by modification time (newest first).
+ The ‘numeric’ specifier treats names consisting solely of digits as
+ numbers and sorts them using the numeric value (so "2" will sort
+ before "10", for example). When using ‘numeric’, names containing

A sort specifier of ‘nosort’ disables sorting completely; the

behavior of sorting by name. If set, a valid value begins with an
optional ‘+’, which is ignored, or ‘-’, which reverses the sort
order from ascending to descending, followed by a sort specifier.
- The valid sort specifiers are ‘name’, ‘size’, ‘mtime’, ‘atime’,
- ‘ctime’, and ‘blocks’, which sort the files on name, file size,
- modification time, access time, inode change time, and number of
- blocks, respectively.
+ The valid sort specifiers are ‘name’, ‘numeric’, ‘size’, ‘mtime’,
+ ‘atime’, ‘ctime’, and ‘blocks’, which sort the files on name, names
+ in numeric rather than lexicographic order, file size, modification
+ time, access time, inode change time, and number of blocks,
+ respectively. If any of the non-name keys compare as equal (e.g.,
+ if two files are the same size), sorting uses the name as a
+ secondary sort key.
For example, a value of ‘-mtime’ sorts the results in descending
order by modification time (newest first).
+ The ‘numeric’ specifier treats names consisting solely of digits as
+ numbers and sorts them using the numeric value (so "2" will sort
+ before "10", for example). When using ‘numeric’, names containing
+ non-digits sort after all the all-digit names and are sorted by
+ name using the traditional behavior.
+
A sort specifier of ‘nosort’ disables sorting completely; the
results are returned in the order they are read from the file
system, and any leading ‘-’ is ignored.

followed by a sort specifier.
The valid sort specifiers are
@samp{name},
+@samp{numeric},
@samp{size},
@samp{mtime},
@samp{atime},
@samp{ctime},
and
@samp{blocks},
-which sort the files on name, file size, modification time, access time,
+which sort the files on name, names in numeric rather than lexicographic order,
+file size, modification time, access time,
inode change time, and number of blocks, respectively.
+If any of the non-name keys compare as equal (e.g., if two files are
+the same size), sorting uses the name as a secondary sort key.
For example, a value of @code{-mtime} sorts the results in descending
order by modification time (newest first).
+The @samp{numeric} specifier treats names consisting solely of digits as
+numbers and sorts them using the numeric value (so "2" will sort before
+"10", for example).
+When using @samp{numeric}, names containing non-digits sort after all
+the all-digit names and are sorted by name using the traditional behavior.
+
A sort specifier of @samp{nosort} disables sorting completely; the results
are returned in the order they are read from the file system,
and any leading @samp{-} is ignored.
