CMP(1)
NAME
cmp − compare two files
USAGE
cmp [ −l ] [ −s ] file1 file2
DESCRIPTION
Cmp compares two specified files. If you specify a dash (−) in place of file1, 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 occurs. 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.
DIAGNOSTICS
Exit code 0 is returned for identical files, 1 for different files, and 2 for an inaccessible or missing argument.
