This is rather easy. Notice that the following is only a sketch, add error reporting to it to your hearts content:

Code:
#! /usr/bin/ksh

typeset -i   iCnt=1
typeset -ZR3 chCnt=""
typeset    chFileMask="XX.YYYY..ZZZ.2014"

while [ $iCnt -le 365 ] ; do
     chCnt=$iCnt
     cat "${chFileMask}.${chCnt}."* > "${chFileMask}.${chCnt}"
     (( iCnt += 1 ))
done

exit 0

The "-ZR3" makes a right-justified, zerofilles string. Feeding it "1" as content makes it "001", etc..

I hope this helps.
