Before, it had to read 2^20 bytes + when copying a 1MiB sparse file. Now, it copies bytes only for the + non-sparse sections of a file. Similarly, to induce a hole in the + output file, it had to detect a long sequence of zero bytes. Now, + it knows precisely where each hole in an input file is, and can + reproduce them efficiently in the output file. mv also benefits + when it resorts to copying, e.g., between file systems. + join now supports -o 'auto' which will automatically infer the output format from the first line in each file, to ensure the same number of fields are output for each line. |
