Usage: ./datelist -b [begin date] -e [end date] -f [date format] -o [output file]

Required input;
-b  ---  Begin date must be in format yyyy-mm-dd 
-e  ---  End date must be in format yyyy-mm-dd 
-f  ---  Date format; ddmmyy / ddmmyyyy / mmddyy / mmddyyyy / yymmdd / yyyymmdd
-o  ---  Path/filename to write the datelist to

Optional input;
-a  ---- Append word/characters (some may need escaping with backslash \ )
-p  ---- Prepend word/characters (some may need escaping with backslash \ )
-s  ---- Desired spacing character (- / . etc. some may need escaping with backslash \ )

Alternative options;
-A  ---  Append numeric values to an existing wordlist (no other switches required)
-P  ---  Prepend numeric values to an existing wordlist (no other switches required)
-v  ---  Version & more detailed information on usage
-h  ---  This help information

Example: ./datelist -b 1900-01-01 -e 2050-12-31 -f ddmmyyyy -o date_wordlist.txt -s -
	 ./datelist -b 1900-01-01 -e 2000-12-31 -f yymmdd -o date_wordlist.txt -p TEST
</code>

**Ejemplo de uso**: Rango y formato 01.01.1970 - 31.12.2000.
<code>bash datelist -b 1970-01-01 -e 2000-12-31 -f ddmmyyyy -o date_wordlist.txt -s .
Listing dates from 1970-01-01 to 2000-12-31 in format ddmmyyyy with spacing character .

> Listing range of years and months ..
> Checking for leapyears and listing correct days per month ..
> Creating desired format with spacing character (if any) .. 
> Tidying up ..

Datelist ../date_wordlist.txt has been created ;

datelist v0.7
24-06-2012


PURPOSE
=======
To quickly ( now it IS relatively quick ;) ) create a list of a range of dates for use in for 
instance password lists to test for possible weak password use.
As from version 0.5, datelist no longer uses the linux 'date' command, but is based on simple 
listing and calculations, this has the benefit that it is much faster and no longer limited 
to dates between 1902 -- 2037.


DEPENDANCIES
============
This script is written to be used on the linux distro BackTrack and has not been tested on 
any other (linux) distro.


USAGE
=====
Creating a date wordlist
------------------------
To creating a date wordlist with datelist, you must enter 4 options;
-b  beginning date
-e  ending date
-f  format of output
-o  output filename
example;
./datelist -b 1999-01-01 -e 1999-01-31 -f ddmmyy -o dates.txt

The dates entered as beginning and ending date MUST be in the
format 'yyyy-mm-dd' to allow the program to work correctly.

The format for the output can ONLY be one of the below;
ddmmyy
ddmmyyyy
mmddyy
mmddyyyy
yymmdd
yyyymmdd

The output filename can be whatever you like, datelist will also
warn you if you are about to overwrite an existing file and allow
you to cancel.


Appending word/characters with -a switch
----------------------------------------
Since 0.7 you can specify to append a word/characters directly with
the command to create the datelist with the -a switch. 

example;
./datelist -b 1999-01-01 -e 1999-01-31 -f mmddyyyy -o dates.txt -s - -a TEST
--> 01-01-1999TEST -- 31-01-1999TEST

Prepending word/characters with -p switch
-----------------------------------------
Since 0.7 you can specify to prepend a word/characters directly with
the command to create the datelist with the -p switch. 

example;
./datelist -b 1999-01-01 -e 1999-01-31 -f mmddyyyy -o dates.txt -s - -p TEST
--> TEST01-01-1999 -- TEST31-01-1999

Using the -s switch to include spacing characters
-------------------------------------------------
By including the -s switch, you tell datelist to include
a spacing character between the days, months and years.
(this will work regardless of the output format you choose to use)

The spacing character can almost be whatever you like, however
certain characters will require escaping (with backslash \).
Exception is forward slash, I hardcoded that one in to work without
escaping as it is a commonly used spacing character in dates.

examples;
./datelist -b 1999-01-01 -e 1999-01-31 -f ddmmyy -o dates.txt -s .
./datelist -b 1999-01-01 -e 1999-01-31 -f ddmmyyyy -o dates.txt -s /
./datelist -b 1999-01-01 -e 1999-01-31 -f yymmdd -o dates.txt -s -
./datelist -b 1999-01-01 -e 1999-01-31 -f yyyymmdd -o dates.txt -s \|
./datelist -b 1999-01-01 -e 1999-01-31 -f mmddyy -o dates.txt -s \~
./datelist -b 1999-01-01 -e 1999-01-31 -f mmddyyyy -o dates.txt -s \*

datelist will then create the wordlist with the spacing character included.


Appending numeric values to the beginning of an existing
(date)wordlist with the -A switch
---------------------------------------------------------
I did not manage to get this function working nicely from the command
line within datelist as I had hoped.
So in order to append numeric values, you need to start datelist as follows;

./datelist -A

Then just follow the prompts which are given to enter;
- file to read from
- number of numeric values to append (max 5)
- output filename


Prepending numeric values to the beginning of an existing
(date)wordlist with the -P switch
---------------------------------------------------------
As with the -A switch, you simply start datelist as follows;

./datelist -P

Then just follow the prompts which are given to enter;
- file to read from
- number of numeric values to append (max 5)
- output filename



BUGS/LIMITATIONS
================
Think slowly sorting things out.. however I am sure that things
will pop up after some time. 
Please comment if you find anything.

CHANGELOG
=========

v0.7
- Fixed a bug with the months of July being excluded.
- Fixed a bug with the leapyear calculations missing on whole century dates.
  Thanks to stepking2 for pointing the above bugs out to me !
- Included the -a and -p switch to allow to append or prepend word/characters
  to the created datelist from the command line.

v0.6
- Included more error checks for input dates and other entries.

v0.5
- Rewrote the method of creating dates so as not to have to be dependant on the 'date' command.
  No more limits on dates ! Yay ! 
  Also much faster.
- Fixed some temporary files not being deleted.

v0.4
- Made datelist able to be run directly from the command line instead of using 
  prompts also allowing input of custom filename for output.
- Improved the method of using spacing characters and the number of characters
  that can be used as spacing characters.
- Included possibilities for appending and prepending using custom files
  for input and output instead of being limited to file 'datelist.txt' as in v0.3.
- Tidied up code.

v0.3
- Tidied up some superfluous code
- Tidied up output when creating datelists
- Added switch -s to allow to insert one of 3 possible spacing characters ( - . / )
  in an existing datelist.txt file.

v0.2
- Added support for various output formats.
- Improved the reliability of different outputs.
- Included option to append/prepend upto 5 numbers.

v0.1
