Need Help in reading N days files from a Directory & combining the files

Hi All,

Request your expertise in tackling one requirement in my project,(i dont have much expertise in Shell Scripting). The requirement is as below,

1) We store the last run date of a process in a file. When the batch run the next time, it should read this file, get the last run date from the file. Using this date, the script should read all the files from the Directory that falls between Current Date & previous run date (the date we got from file) & combine it into one Single file for further processing.

Any help/thoughts on how to accomplish this through Shell Script/multiple commands will be highly appreciated.

Thanks in Advance,

If the timestamp on the file containing the last rundate is the same as the date inside the file, it has to be easier to use the timestamp of the file itself rather than the contents of the file.
For example:
find /logsdir -type f -newer rundatefile -print
