Linux Split split file

Introduction

Split can split a large file into multiple files of a specified size, and the split speed is very fast, splitting a 1G size file takes less than 1S of time, and if you manually perform operations on Windows, the estimate is stuck.

Options

usage:split [OPTION] ... [INPUT [PREFIX]] Outputfixed-size pieces of INPUT to Prefixaa, Prefixab, ...;defaultsize is  +Lines, anddefaultPREFIX is' X'. With no input, or when input is-, read standard input. Mandatory arguments toLongOptions are mandatory for  Shortoptions too. -A,--suffix-length=n use suffixes of length N (default 2) Specifies the suffix length of the split file-B,--bytes=size put size bytes per output file split by byte, default unit byte-C,--line-bytes=size put at bytes of lines per output file specifies the maximum size of a single row, the default unit byte-D,--numeric-suffixes use numeric suffixes instead of alphabetic with numbers as suffixes of the split file-L,--lines=numbers put number lines per output file is split by rows--verbose print a diagnostic just before each output file isopened--help Display ThisHelp and exit--version output version information and exitsize May is (or may be a integer optionally followed by) one of the following : KB +K1024x768, MB +* +M1024x768*1024x768, and so on forG, T, P, E, Z, Y.

1. Splitting according to row

Each 3 lines are split into a file, the split file name begins with a name, and a number is the suffix suffix length of 1

3 1 Name

[email protected] test]# lltotal --rw-r--r--.1Root root6Oct9  +: ANAME0-rw-r--r--.1Root root6Oct9  +: Aname1-rw-r--r--.1Root root2Oct9  +: Aname2-rw-r--r--.1Root root -Oct9  +: -Test

2. Split by Byte

Every three bytes split into a file, by default, no unit is byte, can also take units such as KB,MB, etc.

3 1 New

[Email protected] test]# ls-lNew*-rw-r--r--.1Root root3Oct9  +: -new0-rw-r--r--.1Root root3Oct9  +: -New1-rw-r--r--.1Root root3Oct9  +: -New2-rw-r--r--.1Root root3Oct9  +: -NEW3-rw-r--r--.1Root root2Oct9  +: -New4

Summary

The Spit command is useful, for example, when importing data, splitting a file into concurrent import is much faster.
