- I need to create a log. It needs to be called 
- makefile.yymmdd-x where
- makefile.yymmdd can be done with something like
- makefile.`date +DATE: '%y%m%d`

- ...now the catch... the first time I run this today, I want
- makefile.030331-1
- the next time I want
- makefile.030331-2
- and then 
- makefile.030331-3
- etc. 
- 
- Is there a simple way to do this from bash or csh. 

	For SH derived shells: 

	    x=0
	    do 
		x=`expr $x + 1`
		fn="$pattern-$x"
	    while [ -f $fn ]
