How can you compare two files Binary and notify?

[stondesign]

How can you compare the [FILE1.bin] and [FILE2.bin] and then notify ECHO if file 1 is different from file 2?


I would like to do such a thing!

FILE 1 = FILE 2
if it is equal give command ECHO OK
if it is different give command ECHO ERROR

[stondesign]

the files I have to compare are in HEX

[elzooilogico]

Code: Select all

fc /b path\file1.bin path\file2.bin
if %errorlevel% neq 0 (
  echo(files are different
) else (
  echo(files are identical
 )

see

Code: Select all

fc /?

for further information, and

Code: Select all

for /f

about to capture output of a command

Similar to elzooilogico's answer, but more efficiently and without extraneous output:

Code: Select all

fc /b file1.bin file2.bin >nul && echo OK || echo ERROR
