This is a batch programming issue, so I'm not sure if this is the right
newsgroup. If not, maybe someone could suggest a better one.

In a batch file which runs a backup I want the last line to rename the log
file

name_of_backup_job.txt to

name_of_backup_job_today's date.txt with the date in YMD format so that
files will sort into order properly in a directory listing.

How do I extract the date into a variable, and how can I get it into YMD
format?

Grateful for advice.
