> % find /tmp -mtime 1 -type f |tar cvf my.tar -

eek . . . fundamental problem here . . . you are telling tar to create an 
archive called my.tar and store the file "-" into it.

Try it this way:

find /tmp -mtime 1 -type f -print | tar -T - -c -v -f my.tar

According to the man page (if I unstood it correctly), you can't mix
argument styles ( these styles being no dash 'tar cvf', single dash 'tar
-c -v -f', and double dash 'tar --create --verbose --file').

Therefore none of the following will work:  

	tar -T - cvf my.tar
	tar cvf -T - my.tar
	tar cvf my.tar -T -
	tar --from-file - cvf
	etc . . . 

Read the EXAMPLES section of the man page for more details.

Yours,

Aaron Nelson
