Try using the
date command, like this:
$ mkdir test-`date +%F`-dir
$ dir -ld test*
drwxrwxr-x 2 tom tom 4096 Mar 3 14:26 test-2006-03-03-dir
$
Read the man page on the various formatting options and specify them after the "+" sign as appropriate. Be
sure to keep the single quote marks (`), as I have in my example above, as they instruct the shell to run the command enclosed in them and substitute the output in place where the command appears.
Good luck!
Peace...
