Linux Bash Script to TFTP files over from windows to linux

I require someone with good bash linux scripting skills that has worked with tftpd and tftp files over network from windows to linux boxes. The script needs to so following: 1) tftp config file and read a number from it which tells how many files to tftp over next 2) tftp those files over based on that number 3) put those files back together into one file. I have a script that breaks a big file into multiple pieces in windows so we can tftp over files over 2Gb. The script breaks the files into names like [login to view URL] abc.bin.1 abc.bin.2 etc. your job is to write linux bash script to tftp these files over and put them back together into one big file.
