Compare file1 with file2 . Use standard input if file1 is - . See also comm and diff . The exit codes are as follows:

0 Files are identical. 1 Files are different. 2 Files are inaccessible.



For each difference, print the byte number in decimal and the differing bytes in octal.


Work silently; print nothing, but return exit codes.


Print a message if two files are the same (exit code is 0):

cmp -s old new && echo 'no changes'
