哦，原来参数写错了，我是说macos里执行more -2 怎么无效
MacOS里面执行
> man more
less - opposite of more
-n or --line-numbers
Suppresses line numbers. The default (to use line numbers) may cause less to run more slowly in some cases, especially with a very large input file. Suppressing line numbers with the -n option will avoid this problem. Using line numbers means: the line number will be dis played in the verbose prompt and in the = command, and the v command will pass the current line number to the editor (see also the dis cussion of LESSEDIT in PROMPTS below).
> more -n 3 long.txt
# 每次输出2行, 怎么少了1行？
Linux 里
> man more
more - file perusal filter for crt viewing
-number
The screen size to use, in number of lines.
> more -3 long.txt
# 每次输出3行

但 -n or --line-numbers 的描述看起来不是限制每次输出行数啊。
那段英文到底什么意思啊

写的很清楚了，more -num filename
再举个例子 rm -rf / 一般我们写 rm / -rf 但是在 mac 中 -rf 会被当成文件 |

这个需求是 split
shell 循环读输出就行 |

如果你坚持用 shell 处理，直接读入数组，每一项就是一行
我还是觉得是个 X-Y PROBLEM 为了一个不存在的问题，在反复 hack |
