usage="Usage: $0 [OPTION]... FILE1 [FILE2]
|
|
Compare FILE1 to FILE2 byte by byte, using their uncompressed contents
|
|
if they are compressed. If FILE2 is omitted, compare FILE1 to the
|
|
uncompressed contents of FILE1.gz. Do comparisons like 'cmp' does.
|
|
|
|
Options are the same as for 'cmp'.
|
|
|
|
If a FILE is '-' or missing, read standard input.
