Sort directory with complex numeric file names
I have a directory with a large number (1000s) of files and I need to produce a file listing all the files in the directory ordered "properly" (properly will be explained shortly).
The files have the following naming pattern:
bul_13_5_228_b.txt
bul_1_3_57.txt
bul_13_6_229.txt
bul_13_6_258.txt
bul_13_6_260.txt
bul_1_3_65.txt
bul_1_3_71.txt
bul_13_7_261.txt
bul_13_7_264.txt
Where field:
1 = "bul" and doesn't change
2 = range from 1 to 30
3 = range from 1 to 12
4 = range from 1 to the 1000s
The sorting pattern I want would sort the 2nd field first, in standard order (1, 2, 3... 10, 11 12...) then the 3rd field (1, 2, 3...) and finally the 4th field.
So, using the file names above as an example, the resulting file would sort like this:
bul_1_3_57.txt
bul_1_3_65.txt
bul_1_3_71.txt
bul_13_5_228_b.txt
bul_13_6_229.txt
bul_13_6_258.txt
bul_13_6_260.txt
bul_13_7_261.txt
bul_13_7_264.txt
I've tried variations of ls | sort and find but cannot seem to get this to work right.
Thanks.

Hi,
If I have a directory full of say 100 random files, and I would like to organize them, for example: FILE001, FILE002, FILE003, FILE004, etc.
How would I do this from Terminal, instead of manually changing each file? I'm using Mac OS X, if that makes a difference.
Thank you in advance... (8 Replies)

wrap-and-sort
WRAP-AND-SORT(1) General Commands Manual WRAP-AND-SORT(1)
NAME
wrap-and-sort - wrap long lines and sort items in Debian packaging files
SYNOPSIS
wrap-and-sort [options]
DESCRIPTION
wrap-and-sort wraps the package lists in Debian control files. By default the lists will only split into multiple lines if the entries are
longer than 80 characters. wrap-and-sort sorts the package lists in Debian control files and all .install files. Beside that wrap-and-sort
removes trailing spaces in these files.
This script should be run in the root of a Debian package tree. It searches for control, control.in, copyright, copyright.in, install, and
*.install in the debian directory.
OPTIONS
-h, --help
Show this help message and exit.
-a, --wrap-always
Wrap all package lists in the Debian control file even if the entries are shorter than 80 characters and could fit in one line line.
-s, --short-indent
Only indent wrapped lines by one space (default is in-line with the field name).
-b, --sort-binary-packages
Sort binary package paragraphs by name.
-k, --keep-first
When sorting binary package paragraphs, leave the first one at the top. Unqualified debhelper(7) configuration files are applied to
the first package.
-n, --no-cleanup
Do not remove trailing whitespaces.
-d path, --debian-directory=path
Location of the debian directory (default: ./debian).
-f file, --file=file
Wrap and sort only the specified file. You can specify this parameter multiple times. All supported files will be processed if no
files are specified.
-v, --verbose
Print all files that are touched.
