问个sed初级问题，谢谢

test-> cat quote.txt
The honeysuckle band played all night long for only $90.
It was an evening of splendid music and company.
Too bad the disco floor fell through at 23:00.
The local nurse Miss P.Neave was in attendance.

test-> sed -n '/The/,2'p quote.txt
The honeysuckle band played all night long for only $90.
It was an evening of splendid music and company.
The local nurse Miss P.Neave was in attendance.

test-> sed -n '2,/The/'p quote.txt
It was an evening of splendid music and company.
Too bad the disco floor fell through at 23:00.
The local nurse Miss P.Neave was in attendance.

对sed -n '/The/,2'p quote.txt
和sed -n '2,/The/'p quote.txt
的含义不理解，这两种写法分别是什么含义，谢谢

谢谢楼上的，但对于
sed -n '/The/,2'p quote.txt --匹配第一个含有The的行到第二行
-----------------------------
有些不理解，为什么显示的结果是：
test-> sed -n '/The/,2'p quote.txt
The honeysuckle band played all night long for only $90.
It was an evening of splendid music and company.
The local nurse Miss P.Neave was in attendance.
而不是：
test-> sed -n '/The/,2'p quote.txt
The honeysuckle band played all night long for only $90.
It was an evening of splendid music and company.
呢，谢谢

建议先看Sed基础。

这么简单的问题我来回答吧：
sed -n '/The/,2'p quote.txt --匹配第一个含有The的行到第二行

sed -n '2,/The/'p quote.txt --匹配第二行到下一个含有The的行

解释的不全对， 假设/The/匹配了1行和4行,

则这个/The/,2匹配的地址空间是

1,2
4
这两个

很形象啊。可能楼主过分在意第二行中的第字了。

无声无息

范围是闭合的，开水就要关水，做人有始有终
范围是包含开始的行，结束条件的行，以及两者之间的行。如果结束条件无法满足，就会操作到文件结尾，如果结束条件满足，就继续查找满足开始条件的位置.
