The solution you provided is working perfectly for this scenario.

We also have a requirement where the files are placed in our directory on a daily basis.
In this case, we want the choose and process the file based on a date (placed in our directory) range. The solution you provided is not working in this case as it looking at the file creation date.
As I said before, most filesystems DO NOT STORE a file creation date for files and there is no way to determine the date on which a file was created using standard interfaces. If the last modification timestamp of a file is insufficient for you needs, you need to:
  1. make sure that you are storing these files on a filesystem type that keeps track of file creation dates, find an operating system specific way to look at the file's creation date for files on that filesystem, and find a way to use that operating system specific way of examining files to select the files you want to process,
  2. include the file creation date in the pathnames of your files and select files to process based on the date in each file's pathname, or
  3. put unprocessed files in a separate directory and move them to a different directory after they have been processed.
Since you haven't told us what operating system AND filesystem type you're using, we have no way to guess whether or not what you want is possible with method 1. You can use method 2 or 3 on any operating system.

Can be invoked to charge a number of units to login-name. A record is written to to be merged with other accounting records during the night. Should be initiated via It periodically checks the size of If the size exceeds blocks, 1000 by default, is invoked with argument switch. If the number of free disk blocks in the file system falls below 500, automatically turns off the collection of process accounting records via the argument to When at least this number of blocks is restored, the accounting will be activated again. This feature is sensitive to the frequency at which is executed, usually by Should be invoked by to perform the disk accounting functions. By default, it will do disk accounting on the special files in If the flag is used, it does a slower version of disk accounting by login directory. files specifies the one or more filesystem names where disk accounting is to be done. If files is used, disk accounting will be done on these filesystems only. If the flag is used, files should be mount points of mounted filesystem. If omitted, they should be the special file names of mountable filesystems. Invoked by to update which shows the last date on which each user logged in (see runacct(1M)). Should be invoked once each month or each accounting period. number indicates which month or period it is. If number is not given, it defaults to the current month (01 through 12). This default is useful if is to executed via on the first day of each month. creates summary files in and restarts summary files in Creates file with mode 664 and ensures that owner and group are It is called by various accounting shell procedures. Can be used to print the session record file normally created by (see acctcon(1M)). Invoked by (see runacct(1M)) to format a report of the previous day's accounting data. The report resides in where mmdd is the month and day of the report. The current daily accounting reports may be printed by typing prdaily. Previous days' accounting reports can be printed by using the mmdd option and specifying the exact report date desired. The flag prints a report of exceptional usage by login id for the specifed date. Previous daily reports are cleaned up and therefore inaccessible after each invocation of The flag prints a report of exceptional resource usage by command, and can be used on current day's accounting data only. Can be used to format and print any total accounting file. Should be invoked during a system shutdown to turn process accounting off and append a "reason" record to Should be called by system startup scripts to turn the accounting on whenever the system is brought up. An interface to (see acct(1M)) to turn process accounting or The argument turns accounting off, moves the current to the next free name in then turns accounting back on again.
