Hi Damien, > I think we should fix dd(1).
I like that. Not allowing uppercase violates the principle of least surprise for "M" in particular, but accepting uppercase for all four multipliers is probably most convenient indeed (without documenting it, of course). By the way, while here, i suggest improving the STANDARDS section of the manual page. - ascii, ebcdic, ibm are not required by POSIX, but XSI extensions - sort oldibm and osync alphabetically - note that m and w are not required by POSIX, either Are you OK with that?
