cmp - compare two files SYNOPSIS
cmp [ -l ] [ -s ] file1 file2 DESCRIPTION
The two files are compared. (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 Print the byte number (decimal) and the differing bytes (octal) for each difference. -s Print nothing for differing files; return codes only. SEE ALSO
diff(1), comm(1) DIAGNOSTICS
Exit code 0 is returned for identical files, 1 for different files, and 2 for an inaccessible or missing argument. 7th Edition April 29, 1985 CMP(1)

Under default options, 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. skip1 and skip2 are initial byte offsets into file1 and file2, respectively; and maybe octal or decimal; the form of the number is determined by the environment variable (in the C locale, a leading 0 denotes an octal number. See on environ(5) and strtol(3C)). recognizes the following options: Print the byte number (decimal) and the differing bytes (octal) for each difference (byte numbering begins at 1 rather than 0). Print nothing for differing files; return codes only. EXTERNAL INFLUENCES

If is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of If any internationalization variable contains an invalid setting, behaves as if all internationalization variables are set to "C". See environ(5). International Code Set Support Single- and multi-byte character code sets are supported. DIAGNOSTICS
returns the following exit values: Files are identical. Files are not identical. Inaccessible or missing argument. prints the following warning if the comparison succeeds till the end of file of file1(file2) is reached. SEE ALSO comm(1), diff(1). STANDARDS CONFORMANCE
