[NTLUG:Discuss] Script question: give me the next sequential filename....

[Jack Snodgrass]

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. 

I know that I can use php or rexx or perl to do this, 
but can I do it from simple scripting commands? 

Thanks - jack
