If you have anything other than a tiny file system, it is much faster
to run a single `find' that removes `junk' rather than several separate
`find's.  E.g.:

	pat=`echo -n -name; echo $junkfiles | sed -e 's/ / -o -name /'"
	find / \( $pat \) -exec /bin/rm {} \;

(the assignment to `pat' above can be deleted in the obvious manner);
or just write it directly.  This is the script we run each night:

find / \(	\( -name '#*'			-atime +1 \)	\
	-o	\( -name ',*'			-atime +1 \)	\
	-o	\(	\( -name '*.bak'			\
			-o -name '*.dvi'			\
			-o -name '*.CKP'			\
			-o \(					\
				  -name '*~'			\
				! -name 'Mail.help.~' \)	\
			-o -name '.*.bak'			\
			-o -name '.*.CKP'			\
			-o -name '.*~' \)	-atime +3 \)	\
	-o	\( -name '.emacs_[0-9]*'	-atime +7 \)	\
	-o	\( -name core				  \)	\
\) -print -exec /bin/rm -f {} \; > /tmp/.cleanup 2>&1
