又快又脏:

head -16428 < file.in | tail -259 > file.out

可能不是最好的方法，但应该有用。

顺便说一下:259 = 16482-16224+1。

在这种情况下，您可以使用sed命令，它非常快。

如前所述，让我们假设范围是:在16224和16482行之间

#get the lines from 16224 to 16482 and prints the values into filename.txt file
        sed -n '16224 ,16482p' file.txt > filename.txt 
    
#Additional Info to showcase other possible scenarios:
    
#get the 16224 th line and writes the value to filename.txt

        sed -n '16224p' file.txt > filename.txt 

#get the 16224 and 16300 line values only and write to filename.txt. 

        sed -n '16224p;16300p;' file.txt > filename.txt

我写了一个叫做splitter的Haskell程序，它就是这样做的:阅读我发布的博客文章。

您可以使用该程序如下:

$ cat somefile | splitter 16224-16482

这就是它的全部。您将需要Haskell来安装它。只是:

$ cabal install splitter

这样就做完了。我希望这个程序对您有用。

由于我们讨论的是从文本文件中提取文本行，所以我将给出一个特殊情况，即您希望提取与某个模式匹配的所有行。

myfile content:
=====================
line1 not needed
line2 also discarded
[Data]
first data line
second data line
=====================
sed -n '/Data/,$p' myfile

将打印[Data]行和其余部分。如果想要从第一行到模式的文本，输入:sed -n '1，/Data/p' myfile。此外，如果您知道两个模式(最好在文本中是唯一的)，则可以使用匹配指定范围的开始行和结束行。

sed -n '/BEGIN_MARK/,/END_MARK/p' myfile

我编写了一个小型bash脚本，您可以从命令行运行它，只要您更新PATH以包含它的目录(或者您可以将它放在PATH中已经包含的目录中)。

用法:$ pinch filename起始行结束行

我正准备发布头部/尾部技巧，但实际上我可能只是启动emacs。: -)
