Linux split 拆分文件

Usage: split [OPTION]… [INPUT [PREFIX]]
Output fixed-size pieces of INPUT to PREFIXaa, PREFIXab, …; default size is 1000 lines, and default PREFIX is `x’. With no INPUT, or when INPUT is -, read standard input.

Mandatory arguments to long options are mandatory for short options too.
-a, –suffix-length=N use suffixes of length N (default 2) 指定拆分文件的后缀长度
-b, –bytes=SIZE put SIZE bytes per output file 按字节拆分,默认单位字节
-C, –line-bytes=SIZE put at most SIZE bytes of lines per output file 指定单行的最大大小,默认单位字节
-d, –numeric-suffixes use numeric suffixes instead of alphabetic 用数字作为拆分文件的后缀
-l, –lines=NUMBER put NUMBER lines per output file 按行数进行拆分
–verbose print a diagnostic just before each
output file is opened
–help display this help and exit
–version output version information and exit

SIZE may be (or may be an integer optionally followed by) one of following:
KB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for G, T, P, E, Z, Y. 可以用后缀指定其它的单位
