作用：切割文件
格式:
split [option] [input] [prefix]
-l 指定分割后文件的最大行数
ghostwu@dev:~/linux/split$ cat -n ghostwu.txt 1 What is Memcached? 2 Free & open source, 3 high-performance, 4 distributed memory object caching system, 5 generic in nature 6 but intended for use in speeding up dynamic web applications by alleviating database load. 7 Memcached is an in-memory key-value store for small chunks of arbitrary data 8 (strings, objects) from results of database calls 9 API calls, or page rendering. 10 Memcached is simple yet powerful. 11 Its simple design promotes quick deployment, 12 ease of development 13 and solves many problems facing large data caches. 14 Its API is available for most popular languages.
把ghostwu.txt这个文件，每个文件最大6行，前缀为ghostwu_
ghostwu@dev:~/linux/split$ ls ghostwu.txt ghostwu@dev:~/linux/split$ wc -l ghostwu.txt 14 ghostwu.txt ghostwu@dev:~/linux/split$ split -l 6 ghostwu.txt ghostwu_ ghostwu@dev:~/linux/split$ ls ghostwu_aa ghostwu_ab ghostwu_ac ghostwu.txt ghostwu@dev:~/linux/split$ wc -l ghostwu_ab 6 ghostwu_ab ghostwu@dev:~/linux/split$ wc -l ghostwu_aa 6 ghostwu_aa ghostwu@dev:~/linux/split$ wc -l ghostwu_ac 2 ghostwu_ac
用通配符更简单
ghostwu@dev:~/linux/split$ ls ghostwu_aa ghostwu_ab ghostwu_ac ghostwu.txt ghostwu@dev:~/linux/split$ wc -l ghostwu_* 6 ghostwu_aa 6 ghostwu_ab 2 ghostwu_ac 14 total
-a : 指定切割文件的后缀长度
ghostwu@dev:~/linux/split$ split -l 5 -a 3 ghostwu.txt ghostwu_ ghostwu@dev:~/linux/split$ ls ghostwu_aaa ghostwu_aab ghostwu_aac ghostwu.txt ghostwu@dev:~/linux/split$ wc -l ghostwu_* 5 ghostwu_aaa 5 ghostwu_aab 4 ghostwu_aac 14 total
-d: 使用数字后缀
ghostwu@dev:~/linux/split$ ls ghostwu.txt ghostwu@dev:~/linux/split$ split -l 5 -d ghostwu.txt ghostwu_ ghostwu@dev:~/linux/split$ ls ghostwu_00 ghostwu_01 ghostwu_02 ghostwu.txt ghostwu@dev:~/linux/split$ wc -l ghostwu_* 5 ghostwu_00 5 ghostwu_01 4 ghostwu_02 14 total
-b 按文件大小
ghostwu@dev:~/linux/split$ ls ghostwu.txt ghostwu@dev:~/linux/split$ ls -lh total 4.0K -rw-rw-r-- 1 ghostwu ghostwu 565 5月 20 18:41 ghostwu.txt ghostwu@dev:~/linux/split$ split -b 100 ghostwu.txt ghostwu_ ghostwu@dev:~/linux/split$ ls ghostwu_aa ghostwu_ac ghostwu_ae ghostwu.txt ghostwu_ab ghostwu_ad ghostwu_af ghostwu@dev:~/linux/split$ ls -lh total 28K -rw-rw-r-- 1 ghostwu ghostwu 100 5月 20 18:54 ghostwu_aa -rw-rw-r-- 1 ghostwu ghostwu 100 5月 20 18:54 ghostwu_ab -rw-rw-r-- 1 ghostwu ghostwu 100 5月 20 18:54 ghostwu_ac -rw-rw-r-- 1 ghostwu ghostwu 100 5月 20 18:54 ghostwu_ad -rw-rw-r-- 1 ghostwu ghostwu 100 5月 20 18:54 ghostwu_ae -rw-rw-r-- 1 ghostwu ghostwu 65 5月 20 18:54 ghostwu_af -rw-rw-r-- 1 ghostwu ghostwu 565 5月 20 18:41 ghostwu.txt
