List directories on the basis of name
I have below directories. All directories create as per some some logging software by today so all directories current time is today date.

Code:
Direct 2013-08-12 23123
Direct 2013-08-13 24121
Direct 2013-08-14 34513

Direct 2013-08-31 15435
...........

Direct 2013-09-12 53145
Direct 2013-09-30 65234

Direct 2013-09-30 89642

What i want, i just want to extract following directories which name is like, means current date and last two days old date format directory name list rest not list.

Code:
Direct 2013-11-10 12341
Direct 2013-11-09 12323
Direct 2013-11-08 12235

Hi,

I don't quite get your requirments, but if you need to list today, yesteraday and the day before try something like the following.

Code:
$ date +%Y-%m-%d
2013-11-10
$ date +%Y-%m-%d --date='yesterday'
2013-11-09
$ date +%Y-%m-%d --date='-2 days'
2013-11-08

so for example,
Code:
ls -d Direct\ $(date +%Y-%m-%d --date='-2 days')\ *

would list all directories fitting the pattern

@Skrynesaver: this will work only if you GNU-date, which will be so at Linux-, FreeBSD- and similar systems. Any Unix using a POSIX-compatible date-command will not process this.

I hope this helps.

Here is an awk solution. You can use date command to calculate the 2 days from the current date and pass along with the current date to awk as variables.

Code:
$ find . -name "Direct*" -type d -print | awk '$2 <= "2013-11-10"  && $2 >= "2013-11-08" {print substr($0,3)}' 

Direct 2013-11-08 12235
Direct 2013-11-09 12323
Direct 2013-11-10 12341

This is working fine, but how i can automate that it will automatically put today and last two days date. First it will list the directories and then i can delete the directories.

The reading of the man page of date, especially the various format strings to shape the output, is left as an exercise to the reader.
