问题描述
我最近问了类似的问题如何在换行符后转义反斜杠时插入文件内容只是为了意识到我需要做相反的事情.
I recently asked a similar question How To Insert File Contents After Line Match While Escaping Backslash only to realize I need to do the opposite.
使用该问题中的代码,我尝试过:
Using the code from that question, I have tried:
sed '/<\\tag>/i file2' file1第二次尝试:
awk '/<\\tag>/{print;system("cat File2.txt");before} 1' File1.txt但是,我无法让它在比赛之前插入一行.
However, I'm unable to get it to insert one line before the match.
示例:
File1.txt
File1.txt
Hello <[World!]> 1 Hello <[World!]> 2File2.txt:
File2.txt:
<thanks> <tag> <example> <new> <\new> <\example> <\tag> <\thanks>所需的输出:
<thanks> <tag> <example> <new> <\new> <\example> Hello <[World!]> 1 Hello <[World!]> 2 <\tag> <\thanks>如果您可以帮助我在转义后插入文件内容,同时转义反斜杠,我将不胜感激.
If you could please help me insert the file contents after a line match while escaping a backslash, I would really appreciate it.
推荐答案$ awk 'FNR==NR{n=n $0 ORS; next} /<\\tag>/{$0=n $0} 1' file1 file2 <thanks> <tag> <example> <new> <\new> <\example> Hello <[World!]> 1 Hello <[World!]> 2 <\tag> <\thanks>
