cmp(1) |
 |
cmp − compare two files
cmp [ −l ] [ −s ] file1 file2
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. |
diff(1), comm(1)
Exit code 0 is returned for identical files, 1 for different files, and 2 for an inaccessible or missing argument.
