Sol.
but for above solution my boss has said that
What if there are lakhs of log files in that directory.
Can you think of a way to iterate not more than 30 times?
This is not efficient.
Can some one suggest me to proper way for this

Reason: Add CODE and ICODE tags.
If you have hundreds of thousands of files in a single directory, you have more problems than a script like this will fix. But, running date and awk once for every file in a directory (even if there are only a few files in that directory) is very inefficient when it could all be done with one invocation of awk to process all of the files in the directory.
So, Can you please help me to solve the assignment. is it my approach is wrong
the main problem which I am feeling in solving is the File name is date format which is string and date comparison can be possible only in Numeric format.
And I am new to the Shell scripting can you guide.
