exits 0 on success and \*[Gt]0 if an error occurred.
.Sh MINIX-SPECIFIC notes
If hexdump is compiled on a compiler that does not support long long (that is,
ACK), 64-bit (8 byte) integer formats are not supported. Conversions where this
is the default are changed to use a 32-bit 4 byte) default instead.
.Sh EXAMPLES
Display the input in perusal format:
.Bd -literal -offset indent
