如何删除使用AWK具体线路基础的Sed /在另一个文件中的内容 [英] How can I delete specific lines using awk/sed based on the contents of another file

问题描述

我怎样才能删除基于行号包含在另一个文件中的文件中的特定行？我知道如何通过只提供他们在命令行中删除特定行，但我不知道如何删除基于被包含在另一个文件中的行号专用线。包含行号的文件是格式如下：

How can I delete a specific lines from a file based on line numbers that are contained in another file? I know how to delete specific lines by just providing them on the command line, but I do not know how to delete specific lines based on lines numbers that are contained in another file. The file containing the line numbers is in the following format:

15768
15775
15777
15782
15784
15789
15791
15798
15800
15807
15809
15815
15817
15824
15826

有2073行总说我需要删除。我试图寻找周围如何做到这一点，虽然我不能一个例子与此类似。

There are 2073 lines total that I need to remove. I've tried searching around for how to do this although I was not able to an example similar to this.

感谢您的帮助。

推荐答案

假设要删除的行号文件中的待删除和数据在大数据文件，然后，使用bash的进程替换：

Assuming the line numbers to be deleted are in a file to-be-deleted and the data is in big-data-file, then, using Bash process substitution:

 sed -f <(sed 's/$/d/' to-be-deleted) big-data-file > smaller-data-file

内 SED的/ $ / D'命令行号转换成 SED 删除操作。外 SED 命令读取删除命令，并应用操作的大数据文件。

The inner sed 's/$/d' command converts the line numbers into sed delete operations. The outer sed commands reads the delete commands and applies the operations to the big data file.
