causes hexdump to display all input data.
Without this option, any number of output lines that are identical to the
immediately preceding output line (except for the input offset), are
replaced with a line comprised of a single asterisk. This makes output
more concise e.g. if input contains a long sequence of one repeated byte
specifies the number of hex-dumped bytes per output line.
Minimum is 1, maximum is 10240 but can be changed in the
source. Default is 16.
(flush-mode) causes hexdump to reflect its input immediately.
Without this option, output is buffered (on ttys this means linebuffered,
otherwise even blockbuffered). This option is especially useful, if you
want to watch bytes as they are trickling out of a binary device. (e.g.
For obvious reasons, this implies -v.
at most one inputfile can be given. if none is, then stdin will be used
for input. (Giving more Inputfiles would have no sense.)
On systems where textfiles and binaries are treated differently
(such as MS-DOS) an inputFile should be given, as input-redirection
may be flakey with binary data.
at most one outputfile can be given. if none is, then stdout will be used for output.
