ndisasm - the Netwide Disassembler, an 80x86 binary file disassembler

       The ndisasm command generates a disassembly listing of the binary file infile and directs it to stdout.

-h
           Causes ndisasm to exit immediately, after giving a summary of its invocation options.

       -r|-v
           Causes ndisasm to exit immediately, after displaying its version number.

       -oorigin
           Specifies the notional load address for the file. This option causes ndisasm to get the addresses it
           lists down the left hand margin, and the target addresses of PC-relative jumps and calls, right.

       -ssync-point
           Manually specifies a synchronisation address, such that ndisasm will not output any machine
           instruction which encompasses bytes on both sides of the address. Hence the instruction which starts
           at that address will be correctly disassembled.

       -ehdrlen
           Specifies a number of bytes to discard from the beginning of the file before starting disassembly.
           This does not count towards the calculation of the disassembly offset: the first disassembled
           instruction will be shown starting at the given load address.

       -koffset,length
           Specifies that length bytes, starting from disassembly offset offset, should be skipped over without
           generating any output. The skipped bytes still count towards the calculation of the disassembly
           offset.

       -a|-i
           Enables automatic (or intelligent) sync mode, in which ndisasm will attempt to guess where
           synchronisation should be performed, by means of examining the target addresses of the relative jumps
           and calls it disassembles.

       -bbits
           Specifies 16-, 32- or 64-bit mode. The default is 16-bit mode.

       -u
           Specifies 32-bit mode, more compactly than using ‘-b 32’.

       -pvendor
           Prefers instructions as defined by vendor in case of a conflict. Known vendor names include intel,
           amd, cyrix, and idt. The default is intel.

ndisasm only disassembles binary files: it has no understanding of the header information present in
       object or executable files. If you want to disassemble an object file, you should probably be using
       objdump(1).

       Auto-sync mode won’t necessarily cure all your synchronisation problems: a sync marker can only be placed
       automatically if a jump or call instruction is found to refer to it beforendisasm actually disassembles
       that part of the code. Also, if spurious jumps or calls result from disassembling non-machine-code data,
       sync markers may get placed in strange places. Feel free to turn auto-sync off and go back to doing it
       manually if necessary.
