(If \fIfile1\fP is `\-', the standard ! 20: input is used.) With no options, \fIcmp\fP makes no comment if the ! 21: files are the same; if they differ, it reports the byte and line ! 22: number at which the difference occurred, or, that one file is an ! 23: initial subsequence of the other. \fISkip1\fP and \fIskip2\fP are ! 24: initial byte offsets into \fIfile1\fP and \fIfile2\fP respectively, ! 25: and may be either octal or decimal; a leading ``0'' denotes octal. ! 26: .PP ! 27: Options: ! 28: .TP 6 ! 29: .B \-s ! 30: Print nothing for differing files; set exit codes only. ! 31: .TP 6 ! 32: .B \-l ! 33: Print the byte number (in decimal) and the differing bytes (in octal) ! 34: for all differences between the two files. ! 35: .SH "SEE ALSO" ! 36: diff(1), comm(1) ! 37: .SH DIAGNOSTICS ! 38: Exit code 0 is returned for identical files, 1 for different files, ! 39: and 2 for an inaccessible or missing argument, or a system error.
