I thought order of line is not important, as requester also tried it. By seeing the reply, it seems sort worked fine for him.

Hello all,
I've got a strange behaviour of sort and uniq commands: they do not recognise apparently duplicated lines in a file (already sorted). The lines are identical by eye, but they must differ in smth, because when they are put in two files, those have slightly different size.

fatsort
fatsort(1) General Commands Manual fatsort(1)
NAME
FATSort - FAT filesystem sorting utility
SYNOPSIS
fatsort [options] device
DESCRIPTION
FATsort sorts directory structures of FAT filesystems. Many MP3 hardware players don't sort files automatically but play them in the order
they were transmitted to the device. FATSort can help here.
OPTIONS
-c This option causes FATSort to ignore the case of filenames (e.g. 'example.mp3' is equal to 'EXAMPLE.MP3').
-f Force sorting even if the device is mounted or if FATSort cannot determine if the device is mounted.
-h Shows some help information.
-i Prints some file system information of the specified device.
-l FATSort will not sort directory structures, but just print the current order.
-o type
This options specifies how FATSort will sort files and directories. type can be 'd' for directories before files (which is the
default), 'f' for files before directories, or 'a' for no differentiation between files and directories.
-n Uses natural order to sort directory structures instead of alphanumeric order. For example, an alphanumeric order would be
file123.mp3
file21.mp3
file3.mp3
and the corresponding natural order would be
file3.mp3
file21.mp3
file123.mp3.
-q FATSort will work quietly without printing additional information messages.
-r Sorts the directories in reverse order (Z-A).
-R Sorts the directories in random order.
-v Shows version information only.
The following options can be specified multiple times:
-d directory
Sort directory only
-D directory
Sort directory and all subdirectories
-x directory
Don't sort directory
-X directory
Don't sort directory and all subdirectories
-I prefix
Ignore filename prefix prefix during sorting. For example, passing option -I "the " tells FATSort to sort 'The Beatles.mp3' like
'Beatles.mp3'.
EXAMPLES
Sort FAT filesystem on an USB stick:
fatsort /dev/sda1
Sort FAT filesystem in a file:
fatsort /home/user/fat16_fs.img
Sort directory /dir1 and all subdirectories except /dir1/dirA:
fatsort /dev/sda1 -D /dir1 -x /dir1/dirA
Ignore prefixes 'a ' and 'the ' during sorting:
fatsort /dev/sda1 -I "a " -I "the "
