I have 62000 files in a folder.
Starting from May 17 2004 till Dec 21 2005 ,files are present in this folder.

I want sort these files.All 2004 files i want to keep it in a single folder called "2004_XMls" & rest files i.e 2005 files ,i am going to keep them monthwise.

Just grepping "2004" or "2005" is not working & using egrep is hectic task.

How can i separate all 2004 files from this folder?

file format is like this:
May 18 2004 Ordr_100100000197_180504183038_01.xml
.
.
.
Jan 1 2005 Ordr_100100236163_010105125149_01.xml
.
.


any ideas on using "awk with xargs"?

To get all 2004 files from the ls output, use
This will give you the filenames.

A better way is to use find in coordination with touch. Touch a file that has a date/time stamp of 01 Jan 2005 00:00. Then run a find on the directory to find files that are older than this file. This will give you files of 2004. Then run a find to get files newer than this file. This should give you files as of 2005.
