Mac ls sort by name

You can sort the contents by size of the file with the largest size being listed first, by using the -S option.

You can sort the output to show the smallest file first by using the reverse -r option. Another option -X provides the ability to sort by extension. This allows you to display files grouped by extensions. Though ls provides some sorting options as mentioned above, it does not have the ability to sort by many of the other file attributes, such as owner name or group name.

But you can still sort by these fields by piping the output through to the sort command. In order to use the sort command to sort the output of ls , you should make sure that the field that you want to sort by is displayed by the ls command. The -l option prints out the long listing format which works for most cases. This will print out the attributes in a column mode. Now find the field or attribute that you want to sort by and its column or field number.

Just count out the columns, for example in the above sample output the month is column 6 and the file name is column 9. Depending on the ls version and the options you use, the columns can change. To sort by a particular column, pipe the output of the ls to the sort command and specify the column or field number.

So, to sort by owner name, which is in field 3 you would do. Another useful command to know is the awk, which will actually let you prune the output to just the desired fields.

Sorting files using the ls command

This allows for an easier sorting and cleaner display. Automatically set for the super-user unless -I is specified. The argument format is a string used by strftime 3. Depending on the choice of format string, this may result in a different number of columns in the output. This option overrides the -T option.

See below. This option is assumed if none of the -F , -d , or -l options are specified. This option cancels the -P option. This option cancels the -H and -L options. The -D option gives even more control over the output format.

For compatibility with GNU coreutils, ls supports yes or force as equivalent to always , no or none as equivalent to never , and tty or if-tty as equivalent to auto. This option turns on -a. It also negates the effect of the -r , -S and -t options.

Block sizes and directory totals are handled as described in The Long Format subsection below, except if the long format is not also requested the directory totals are not output when the output is in a single column, even if multi-column output is requested. If two files have the same modification timestamp, sort their names in ascending lexicographical order.

The -r option reverses both of these sort orders. Note that these sort orders are contradictory: the time sequence is in descending order, the lexicographical sort is in ascending order. This feature can cause problems listing files stored with sequential names on FAT file systems, such as from digital cameras, where it is possible to have more than one image with the same timestamp. In such a case, the photos cannot be listed in the sequence in which they were taken. This causes ls to reverse the lexicographical sort order when sorting files with the same modification timestamp.

This is the default when output is not to a terminal. See the description of the -t option for more details.

Force output to be one entry per line. If no locale is set, or the locale does not have a non-monetary separator, this option has no effect. The -1 , -C , -x , and -l options all override each other; the last one specified determines the format used.

linux ls sort by size, by time, by name, by type

The -c , -u , and -U options all override each other; the last one speci- fied determines the file time used. The -S and -t options override each other; the last one specified deter- mines the sort order used. The -B , -b , -w , and -q options all override each other; the last one specified determines the format used for non-printable characters. The -H , -L and -P options all override each other either partially or fully ; they are applied in the order specified. By default, ls lists one entry per line to standard output; the excep- tions are to terminals or when the -C or -x options are specified.

The Long Format If the -l option is given, the following information is displayed for each file: file mode, number of links, owner name, group name, MAC label, number of bytes in the file, abbreviated month, day-of-month file was last modified, hour file last modified, minute file last modified, and the pathname. If the modification time of the file is more than 6 months in the past or future, and the -D or -T are not specified, then the year of the last modification is displayed in place of the hour and minute fields.

If the owner or group names are not a known user or group name, or the -n option is given, the numeric ID's are displayed. If the file is a character special or block special file, the device num- ber for the file is displayed in the size field. The listing of a directory's contents is preceded by a labeled total num- ber of blocks used in the file system by the files which are listed as the directory's contents which may or may not include.

The default block size is bytes. Numbers of blocks in the output will have been rounded up so the numbers of bytes is at least as many as used by the corresponding file system blocks which might have a different size. The file mode printed under the -l option consists of the entry type and the permissions. The entry type character describes the type of file, as follows: - Regular file. The next three fields are three characters each: owner permissions, group permissions, and other permissions.
