Free selection sort software for linux

Archive sort is a bash script that sorts directories into manageable 4.4GB directories for the purpose of archiving onto DVDs.

It is useful if you have several tens or hundreds of GBs of data to archive. It can also be configured to sort into 700MB directories for archiving onto CDs.

Usage: ./archive-sort [-h] [-s SIZE] [-t] [-v] SOURCE DEST

Archive files from directory DEST to new directory SOURCE in 4.4GB chunks,
or any SIZE specified by the user.

This script has not been tested extensively, so it is recommended that you make a copy of the directory you want to archive, then run the script on that directory. Always use the -t (test) option first and carefully read the output before using the script.

Optional arguments.

-h Print this help message.
-s Size of the archive media (default 4.4 GB)
-t Test run with verbose messages.
-v Verbose

Examples:

First cd to directory containing directories to be archived:

cd /home/user/archive
archive-sort . ../disc01

This is useful if you have several large directories under /home/user/archive, but no files. The archive directory will not be included in disc01.

If you have a directory full of lots of files, then cd to the parent directory of the directory that needs to be archived:

cd /home/user
archive-sort archive disc01

MediaSort is a tool that indexes, sorts, and renames media files such as pictures and MP3s based on any of their metadata attributes.
For example, you can sort your pictures by date, size, or other EXIF attributes, or MP3s by author, album, or other ID3 tag values. MediaSort is also a "sorting" Ant FileMapper that can be used with any other Ant tasks to achieve more complex work.
Enhancements:
- Solve major incompatibility with JDK 1.4

Genre-sort is a handy Python script that will move/copy mp3s based on their id3 genre tag.
Main features:
- Written in Python
- Uses the eyeD3 library http://eyed3.nicfit.net/
- Currently only works on mp3 but ogg vorbis and flac support is planned
Examples:
./genre-sort.py /dir/to/files -p
Will run in pretend mode and show you what the script plans to do.
./genre-sort.py /dir/to/files -c
Will make copies of the files in the correct directories and leave the originals behind.
./genre-sort.py /dir/to/files
Default behavior will move files to the correct directories and delete the originals.

File::Sort is a Perl module to sort a file or merge sort multiple files.

SYNOPSIS

use File::Sort qw(sort_file);
sort_file({
I => [qw(file_1 file_2)],
o => file_new, k => 5.3,5.5rn, -t => |
});

sort_file(file1, file1.sorted);

This module sorts text files by lines (or records). Comparisons are based on one or more sort keys extracted from each line of input, and are performed lexicographically. By default, if keys are not given, sort regards each input line as a single field. The sort is a merge sort. If you dont like that, feel free to change it.

Options

The following options are available, and are passed in the hash reference passed to the function in the format:

OPTION => VALUE

Where an option can take multiple values (like I, k, and pos), values may be passed via an anonymous array:

OPTION => [VALUE1, VALUE2]

Where the OPTION is a switch, it should be passed a boolean VALUE of 1 or 0.
This interface will always be supported, though a more perlish interface may be offered in the future, as well. This interface is basically a mapping of the command-line options to the Unix sort utility.

I INPUT

Pass in the input file(s). This can be either a single string with the filename, or an array reference containing multiple filename strings.

c

Check that single input fle is ordered as specified by the arguments and the collating sequence of the current locale. No output is produced; only the exit code is affected.

m

Merge only; the input files are assumed to already be sorted.

o OUTPUT

Specify the name of an OUTPUT file to be used instead of the standard output.

u

Unique: Suppresses all but one in each set of lines having equal keys. If used with the c option check that there are no lines with consecutive lines with duplicate keys, in addition to checking that the input file is sorted.

y MAX_SORT_RECORDS

Maximum number of lines (records) read before writing to temp file. Default is 200,000. This may eventually change to be kbytes instead of lines. Lines was easier to implement. Can also specify with MAX_SORT_RECORDS environment variable.

F MAX_SORT_FILES

Maximum number of temp files to be held open at once. Default to 40, as older Windows ports had quite a small limit. Can also specify with MAX_SORT_FILES environment variable. No temp files will be used at all if MAX_SORT_RECORDS is never reached.

D

Send debugging information to STDERR. Behavior subject to change.
The following options override the default ordering rules. When ordering options appear independent of any key field specifications, the requested field ordering rules are applied globally to all sort keys. When attached to a specific key (see k), the specified ordering options override all global ordering options for that key.

d

Specify that only blank characters and alphanumeric characters, according to the current locale setting, are significant in comparisons. d overrides i.

f

Consider all lower-case characters that have upper-case equivalents, according to the current locale setting, to be the upper-case equivalent for the purposes of comparison.

i

Ignores all characters that are non-printable, according to the current locale setting.

n

Does numeric instead of string compare, using whatever perl considers to be a number in numeric comparisons.

r

Reverse the sense of the comparisons.

b

Ignore leading blank characters when determining the starting and ending positions of a restricted sort key. If the b option is specified before the first k option, it is applied to all k options. Otherwise, the b option can be attached indepently to each field_start or field_end option argument (see below).

t STRING

Use STRING as the field separator character; char is not considered to be part of a field (although it can be included in a sort key). Each occurrence of char is significant (for example, delimits an empty field). If t is not specified, blank characters are used as default field separators; each maximal non-empty sequence of blank characters that follows a non-blank character is a field separator.

X STRING

Same as t, but STRING is interpreted as a Perl regular expression instead. Do not escape any characters (/ characters need to be escaped internally, and will be escaped for you).

The string matched by STRING is not included in the fields themselves, unless demanded by perls regex and split semantics (e.g., regexes in parentheses will add that matched expression as an extra field). See perlre and "split" in perlfunc.

R STRING

Record separator, defaults to newline.

k pos1[,pos2]

The keydef argument is a restricted sort key field definition. The format of this definition is:

field_start[.first_char][type][,field_end[.last_char][type]]

where field_start and field_end define a key field restricted to a portion of the line, and type is a modifier from the list of characters b, d, f, i, n, r. The b modifier behaves like the b option, but applies only to the field_start or field_end to which it is attached. The other modifiers behave like the corresponding options, but apply only to the key field to which they are attached; they have this effect if specified with field_start, field_end, or both. If any modifier is attached to a field_start or a field_end, no option applies to either.

Occurrences of the k option are significant in command line order. If no k option is specified, a default sort key of the entire line is used. When there are multiple keys fields, later keys are compared only after all earlier keys compare equal.
Except when the u option is specified, lines that otherwise compare equal are ordered as if none of the options d, f, i, n or k were present (but with r still in effect, if it was specified) and with all bytes in the lines significant to the comparison. The order in which lines that still compare equal are written is unspecified.

pos +pos1 [-pos2]

Similar to k, these are mostly obsolete switches, but some people like them and want to use them. Usage is:

+field_start[.first_char][type] [-field_end[.last_char][type]]

Where field_end in k specified the last position to be included, it specifes the last position to NOT be included. Also, numbers are counted from 0 instead of 1. pos2 must immediately follow corresponding +pos1. The rest should be the same as the k option.

Mixing +pos1 pos2 with k is allowed, but will result in all of the +pos1 pos2 options being ordered AFTER the k options. It is best if you Dont Do That. Pick one and stick with it.

Here are some equivalencies:

pos => +1 -2 -> k => 2,2
pos => +1.1 -1.2 -> k => 2.2,2.2
pos => [+1 -2, +3 -5] -> k => [2,2, 4,5]
pos => [+2, +0b -1] -> k => [3, 1b,1]
pos => +2.1 -2.4 -> k => 3.2,3.4
pos => +2.0 -3.0 -> k => 3.1,4.0

Heimer is 48 ears old.
John is 33 ears old.
Jacob is 29 ears old.
Jingle is 15 ears old.
Smitz is 12 ears old.

Sort MP3 is a script was made to help in organizing MP3s. If you have one directory with allot of mp3s and the names are not very readable you can run this script against them. It will read the id tag of a mp3 and rename the file to the title of the song but with _ instead of spaces. It can also create a directory structure from the id tag if the -c option is used. The structure will be put in the same directory the mp3s are in. It will be something like: "/BANDNAME/CDTITLE/SONG.mp3"

Usage: sort_mp3.pl [options]
Options should be separated by a space and my be
in any order.

-c Create a directory structure from the mp3 tag.
It is made inside the directory holding the un-named mp3s.
If not set the files will just be renamed.
Example: "/BANDNAME/CDTITLE/SONG.mp3"

-d= Path to the directory where mp3s can be found.
There should be no / at the end and no spaces.
Example: "-d=/unsorted_mp3s"
