You need to use a Linux-cmd-line application to compare binary files and exit the first incorrect match

Is there a Linux command line application that will compare two binaries and exit the first incorrect match?

cmpseems to have no way out.

cmp does not have this option, since it always leaves the first mismatch.

$ cmp -b /bin/ls /bin/sed
/bin/ls /bin/sed differ: byte 25, line 1 is 320 M-P 300 M-@

I think you could use 3 tools:

  • cmp
  • diff
  • md5sum

cmp , diff diff , . diff .

, . diff -q, cmp -s, : 0, 1, .

cmp , () (, ): , N N M, (.. N = 10 M = 20):

cmp file1 file2 10 20

md5sum , , MD5 , , , , . , .
