Just use IDA PRO  https   www hex-rays com products ida index shtml  to disassemble the file  and search for some known command line option  using Search   Text  - in that section you will then typically see all the command line options - for the program  LIB2NIST exe  in the screenshot below  for example  it shows a documented command line option   COM2TAG  but also some undocumented ones  like  L  Hope this helps

Unless the writer of the executable has specifically provided a way for you to display a list of all the command line switches that it offers  then there is no way of doing this   As Marcin suggests  the typical switches for displaying all of the options are either    or  help  some applications might prefer the Unix-style syntax  -  and -help  respectively   But those are just a common convention   If those don t work  you re out of luck  You ll need to check the documentation for the application  or perhaps try decompiling the executable  if you know what you re looking for

Really this is an extension to Marcin s answer    But you could also try passing  rubbish  arguments to see if you get any errors back  Getting any response from the executable directly in the shell will mean that it is likely looking at the arguments you re passing  with an error response being close to a guarantee that it is    Failing that you might have to directly ask the publishers creators owners    sniffing the binaries yourself just seems like far too much work for an end-user

The easiest way would be to use use ProcessExplorer but it would still require some searching   Make sure your exe is running and open ProcessExplorer  In ProcessExplorer find the name of your binary file and double click it to show properties  Click the Strings tab  Search down the list of string found in the binary file  Most strings will be garbage so they can be ignored  Search for anything that might possibly resemble a command line switch  Test this switch from the command line and see if it does anything   Note that it might be your binary simply has no command line switches   For reference here is the above steps applied to the Chrome executable  The command line switches accepted by Chrome can be seen in the list
