BTW: "REN *.log *.old" in /bin/ksh is just:
for a in *.log ; do mv $a ${a%.log}.old ; done
Or many other sh-family shells.
If none of the files have ".log" in any other place in their names,
there's a program I wrote long ago that could do this with
MV .log .old *.log
I don't think it's available for fetch anywhere at the moment. I
really should clean it (and the related CP and LN programs) up,
document them, and release them. (In the meantime, I'll be happy to
mail out copies to them as wants.)
