Hi, i write this message regarding to my previous bug report, i have see 
just now that posix section of manpages say:
"The cmp utility shall write no output files are the same. Under default 
options, if they differ, it  shall write tostandard  output the byte and 
line number at which the first difference occurred. Bytes and lines 
shall be numbered beginning with 1."

so now it's all clare.
