cmp - compare two files
cmp [-l | -s] file1 file2 [skip1 [skip2]]
The cmp utility compares two files of any type and writes the results to the standard output. By default, cmp is silent if the files are the same; if they differ, the byte and line number at which the first difference occurred is reported.
Bytes and lines are numbered beginning with one.
The following options are available:
The optional arguments skip1 and skip2 are the byte offsets from the beginning of file1 and file2, respectively, where the comparison will begin. The offset is decimal by default, but may be expressed as an hexadecimal or octal value by preceding it with a leading ‘’0x’’ or ‘’0’’.
The cmp utility exits with one of the following values:
diff(1) , diff3(1)
The cmp utility is expected to be IEEE Std 1003.2 ("POSIX.2") compatible.
