Hammer & Screwdriver Some of the logic needed

I put my example to a file, and then used cat to show the output. The cat command is not really needed, you could pipe your ls output directly to the grep part of my example.

Code:
> cat file121

XMAS200812220199.txt

> today=`date "+%Y%m%d"`
> cat file121 | grep "XMAS${today}01[0-9][0-9].txt"

E.g. --criteria="weaknt:0.8 strongnt:0.5" Valid criteria are: unbalanced weaknt strongnt twont strongtwo weaktwo three twoclubs 4441 singlesuit twosuits partscore game slam game-invite slam-invite jumpshift jumpfit splinter bacon weird --probability=factor Generate hands matching the criteria with only the given probability.

A factor of about 0.8 gives roughly half matching boards AUTHOR
