将在特定的行号与行awk或者sed [英] Insert a line at specific line number with sed or awk

问题描述

我有我需要另一个脚本修改插入在8号线的文本脚本文件。

要插入的字符串： PROJECT_NAME = sowstest ，进入一个名为启动

我试着用awk和sed，但我的命令是越来越乱码。

解决方案

  SED -i8i8这是8号线FILE
 

在第8行插入

  8这是8号线
 

到文件文件

-i 做的修改直接file文件，没有输出到stdout，如由格伦·杰克曼的评论中提到。

I have a script file which I need to modify with another script to insert a text at the 8th line.

String to insert: Project_Name=sowstest, into a file called start.

I tried to use awk and sed, but my command is getting garbled.

解决方案

sed -i '8i8 This is Line 8' FILE

inserts at line 8

8 This is Line 8

into file FILE

-i does the modification directly to file FILE, no output to stdout, as mentioned in the comments by glenn jackman.
