	I have a PS2/80 running AIX 1.1.

	Is there a utility that will let me compare 2 3.5 diskettes to each
	other? Put one on rfd0, one on rfd1 and see if they match byte per byte?

	Thanks. There is no PS2 or AIX group. I thought you guys might know.

diff /dev/rfd0 /dev/rfd1 | pg

The '| pg' just pauses the output incase there are many differences.

Try "cmp /dev/rfd0 /dev/rfd1".  Just a guess.  Unfortunately, this is
likely to take a fair while if it works like the RT does under AIX,
because blocking will fail.  To make things work better, use dd to
read the files and specify a large ibs= which is a multiple of 512.

Ed Clarke (hi, Ed) suggested using diff.  cmp should be significantly
faster, and is probably a better fit for "byte per byte" comparisons.
