split 命令使用方法
split -b 1073741824 -a 2 --numeric-suffixes=1 --additional-suffix=.splt ../abc-v1.0.tar.gz abc-
结果会生成 abc-01.splt 这样的文件。每个文件最大为 1GB
-b指定每个文件的字节大小-a自动生成的文件的后缀长度--numeric-suffixes自动程程的后缀的初始值--additional-suffix=附加的后缀
几个常用的文件大小
- 1KB - 1024 B
- 1MB - 1048576 B
- 1GB - 1073741824 B
- 1TB - 1099511627776 B
help 信息如下
# split --help
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 generate suffixes of length N (default 2)
--additional-suffix=SUFFIX append an additional SUFFIX to file names
-b, --bytes=SIZE put SIZE bytes per output file
-C, --line-bytes=SIZE put at most SIZE bytes of lines per output file
-d, --numeric-suffixes[=FROM] use numeric suffixes instead of alphabetic;
FROM changes the start value (default 0)
-e, --elide-empty-files do not generate empty output files with '-n'
--filter=COMMAND write to shell COMMAND; file name is $FILE
-l, --lines=NUMBER put NUMBER lines per output file
-n, --number=CHUNKS generate CHUNKS output files; see explanation below
-u, --unbuffered immediately copy input to output with '-n r/...'
--verbose print a diagnostic just before each
output file is opened
--help display this help and exit
--version output version information and exit
SIZE is an integer and optional unit (example: 10M is 10*1024*1024). Units
are K, M, G, T, P, E, Z, Y (powers of 1024) or KB, MB, ... (powers of 1000).
CHUNKS may be:
N split into N files based on size of input
K/N output Kth of N to stdout
l/N split into N files without splitting lines
l/K/N output Kth of N to stdout without splitting lines
r/N like 'l' but use round robin distribution
r/K/N likewise but only output Kth of N to stdout
