CMP(1)                               SysV                               CMP(1)



NAME
     cmp - compare two files

SYNOPSIS
     cmp [ -l ] [ -s ] file1 file2

DESCRIPTION
     cmp compares two files.  (If file1 is -, the standard input is used.)
     Under default options, cmp makes no comment if the files are the same; if
     they differ, it announces the byte and line number at which the
     difference occurred.  If one file is an initial subsequence of the other,
     that fact is noted.

OPTIONS
     -l        Prints the byte number (decimal) and the differing bytes
               (octal) for each difference.

     -s        Prints nothing for differing files; return codes only.

DIAGNOSTICS
     Exit code 0 is returned for identical files, 1 for different files, and 2
     for an inaccessible or missing argument.
