Thanks for the reply. Using the method suggested in the links, I was able to construct the following command, which works:
touch -t 201101310001 begin2011
touch -t 201112310001 end2011
find -type f -iname '*.doc' -newer begin2011 ! -newer end2011
From here, I was able to append any further action such as:
-exec cp {} /somelocation \;
While it works fine, it does seem rather involved, with three steps instead of one. Is it not possible to use the 'find' command to simply search for a year, a month or a particular date as one can with the 'ls' command?
