How long does it take to run your mysql command? How much variation is there in the time it takes to run your mysql command?

If you want to run your command 12 times/minute, don't you want the seconds in output filename? As in:
Code:
mysql -ufoo --password='' -te "show full process list" > /home/foo/log/show_processlist.log.`date +%Y%m%d-%H%M%S` 2>&1

If not, the output from the first 11 times you run it will be overwritten by the last time it runs in that minute?

Or, didi you intend to store the output of running your command 12 times in each file with the output from later runs appended to the file instead of replacing the previous contents? As in:
Code:
mysql -ufoo --password='' -te "show full process list" >> /home/foo/log/show_processlist.log.`date +%Y%m%d-%H%M` 2>&1
