I need to compare a unique file name (abc_01312012)

I need to compare a unique file name (abc_01312012) to the system to copy over the current files date to another server using a batch file. There will be multiple files in this directory with the same perfix but the date (suffix) will always be different. I have already got the code to check for the current date and put it in a variable if needed. This is my first time writing a batch, Any help would be great.
