split 命令

常用示例

说明

split divides a file into smaller pieces. By default, it creates files with 1000 lines each, named with a prefix (default: x) followed by a suffix (aa, ab, ac, ...). The command is useful for breaking large files for transmission, processing, or storage limitations. It works with both text and binary files. Size specifications accept suffixes: K (kilobytes), M (megabytes), G (gigabytes), and also KB, MB, GB for powers of 1000. Split reads from stdin if no file is specified or if file is -.
