CMP(1)              RISC/os Reference Manual               CMP(1)



NAME
     cmp - perform a byte-to-byte comparison of two files

SYNOPSIS
     cmp [-l] filename1 filename2 [skip1] [skip2]
     cmp [-s] filename1 filename2 [skip1] [skip2]

DESCRIPTION
     cmp compares filename1 and filename2. If filename1 is '-',
     the standard input is used.  With no options, cmp makes no
     comment if the files are the same; if they differ, it
     reports the byte and line number at which the difference
     occurred, or, that one file is an initial subsequence of the
     other.  skip1 and skip2 are initial byte offsets into
     filename1 and filename2 respectively, and may be either
     octal or decimal; a leading 0 denotes octal.

     The following options are available:

     -l   Print the byte number (in decimal) and the differing
          bytes (in octal) for all differences between the two
          files.

     -s   Silent.  Print nothing for differing files; set exit
          codes only.

DIAGNOSTICS
     Exit code 0 is returned for identical files, 1 for different
     files, and 2 for inaccessible or missing argument, or a sys-
     tem error.
