我正在阅读 split --help，但我不确定如何使用循环功能执行此命令，有人可以给我举个例子吗
Usage: split [OPTION]... [FILE [PREFIX]]
-n, --number=CHUNKS generate CHUNKS output files; see explanation below
The SIZE argument is an integer and optional unit (example: 10K is 10*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/records
l/K/N output Kth of N to stdout without splitting lines/records
--> r/N like 'l' but use round robin distribution
r/K/N likewise but only output Kth of N to stdout

在 Bash 中执行的示例：
# create a testfile with 10 lines
$ printf 'line %s\n' {1..10} > testin
# split into 3 files with round robin distribution and numeric suffix (`-d`)
$ split -d -nr/3 testin testout
# show line count
$ wc -l testout*
4 testout00
3 testout01
3 testout02
10 total
# show content
$ head testout*
==> testout00 <==
line 1
line 4
line 7
line 10
==> testout01 <==
line 2
line 5
line 8
==> testout02 <==
line 3
line 6
line 9
