Old 05-16-2013
but my folder structure is
Code:
 
 
2001-2100/01-12/01-30/files

If we remove dates in removal process based on 541 criteria , 1-30 , then automatcally month folder should be removed,

in removal process, if there is no month folder, then year folder must be removed automatically

Thanks,

I changed retention criteria from 541 days to 455 days , we need to remove all parent and children folders and files inside date folders from from feb 15, 2012 to older dates . but 2012 and feb month folder will be there untill we hit 455 lmit on feb 01 ,2012.

so if we calculate , we need to remove all files in 2010/01-12/01-31 folders and 2011/01-12/01-31 foders and in the year 2012, we will keep till feb 03 and 15 days of files in feb to make it 455 days

it should consider backward when counting number of dates, 2013/may, 2013/apr,2013/mar,2013/feb,2013/jan , 2012/dec, 2012/nov, 2012/oct, 2012/sept,2012/aug,2012/jul, 2012/jun, 2012/may,2012/apr,2012/mar,2012/feb , then keep files inside of folder date from 28 to 13 to retain 455 days of files. file exist only in date folders.

I want to add a few things to addition to above mentioned points. This might help you understand my requirement more clearly

Designing criteria:
1. its desined to hold files in hierarchical folder structure of year/months/dates/files
2. root folder contain year folders
3. Year folder contains month folders
4. month folder contains date folders
5. date folders contain data files
6. date folder contains only the data files that particular date produced.
7. remove all data files which is older than 455 days
8. remove all date folders which is older than 455 days
9. remove all months folder if they do not contain any date folders due to 455 days removal process
10.remove all year folders if they do not contain any months folders due to above process
11. script should consider from 2000 to 2100 years or dynamic
it should be removed as the following direction, for example considering today is may 15 2013,
then folder 2013/05/15 to 2012/02/29-14 should be retained and rest of the olders date, months and years folders
should be removed

Code:
 
 
YEAR MONTH DAY
2013 5 15
2013 4 30
2013 3 31
2013 2 28
2013 1 31
2012 12 31
2012 11 30
2012 10 31
2012 9 30
2012 8 31
2012 7 31
2012 6 30
2012 5 31
2012 4 30

       It then reads a line of text from the keyboard and adds it to the end of the file log.  The echo  ':  c'  command  displays  a	:  (colon)
