使用sed命令在File中的两个模式之间添加文本

I want to add Some large code between two patterns:

我想在两个模式之间添加一些大代码:

File1.txt

This is text to be inserted into the File.

infile.txt

Some Text here
First
Second
Some Text here

I want to add File1.txt content between First and Second :

我想在First和Second之间添加File1.txt内容:

Desired Output:

Some Text here
First
This is text to be inserted into the File.
Second
Some Text here

I can search using two patterns with sed command ,But I don't have idea how do I add content between them.

我可以使用sed命令使用两种模式进行搜索,但我不知道如何在它们之间添加内容。

sed '/First/,/Second/!d' infile

4 个解决方案

Since /r stands for reading in a file, use:

由于/ r代表读取文件,请使用:

sed '/First/r file1.txt' infile.txt

You can find some info here: Reading in a file with the 'r' command.

您可以在这里找到一些信息:使用'r'命令读取文件。

Add -i (that is, sed -i '/First/r file1.txt' infile.txt) for in-place edition.

为就地版添加-i(即sed -i'/ First / r file1.txt'infile.txt)。

To perform this action no matter the case of the characters, use the I mark as suggested in Use sed with ignore case while adding text before some pattern:

要执行此操作,无论字符是什么情况,请在使用sed with ignore case时建议使用I标记,同时在某些模式之前添加文本:

sed 's/first/last/Ig' file

As indicated in comments, the above solution is just printing a given string after a pattern, without taking into consideration the second pattern.

如评论中所示,上述解决方案仅仅是在模式之后打印给定的字符串,而不考虑第二模式。

To do so, I'd go for an awk with a flag:

要这样做,我会去拿一个带旗帜的awk:

awk -v data="$(<patt_file)" '/First/ {f=1} /Second/ && f {print data; f=0}1' file

Given these files:

鉴于这些文件:

$ cat patt_file
This is text to be inserted
$ cat file
Some Text here
First
First
Second
Some Text here
First
Bar

Let's run the command:

让我们运行命令:

$ awk -v data="$(<patt_file)" '/First/ {f=1} /Second/ && f {print data; f=0}1' file
Some Text here
First                             # <--- no line appended here
First
This is text to be inserted       # <--- line appended here
Second
Some Text here
First                             # <--- no line appended here
Bar

i think you can try this

我想你可以尝试一下

$ sed -n 'H;${x;s/Second.*\n/This is text to be inserted into the File\
&/;p;}' infile.txt

#3

awk flavor:

awk '/First/ { print $0; getline < "File1.txt" }1' File2.txt

Here's a cut of bash code that I wrote to insert a pattern from patt_file. Essentially had had to delete some repetitious data using uniq then add some stuff back in. I copy the stuff I need to put back in using lineNum values, save it to past_file. Then match patMatch in the file I'm adding the stuff to.

这是我编写的用于从patt_file插入模式的bash代码的一部分。基本上不得不使用uniq删除一些重复数据然后添加一些东西。我复制我需要放回使用lineNum值的东西,将其保存到past_file。然后在我正在添加内容的文件中匹配patMatch。

   #This pulls the line number from row k, column 2 of the reduced repitious file       
   lineNum1=$(awk -v i=$k -v j=2 'FNR == i {print $j}' test.txt)    

    #This pulls the line number from row k + 1, coulmn 2 of the reduced repitious file
    lineNum2=$(awk -v i=$((k+1)) -v j=2 'FNR == i {print $j}' test.txt)

    #This pulls fields row 4, 2 and 3 column into with tab spacing (important) from reduced repitious file 
    awk -v i=$k -v j=2 -v h=3 'FNR == i {print $j"  "$h}' test.txt>closeJ.txt

    #This substitutes all of the periods (dots) for \. so that sed will match them
    patMatch=$(sed 's/\./\\./' closeJ.txt)

    #This Selects text in the full data file between lineNum1 and lineNum2 and copies it to a file 

    awk -v awkVar1=$((lineNum1 +1)) -v awkVar2=$((lineNum2 -1)) 'NR >= awkVar1   && NR <= awkVar2 { print }' nice.txt >patt_file.txt 

    #This inserts the contents of the pattern matched file into the reduced repitious file              
    #The reduced repitious file will now grow
    sed -i.bak "/$patMatch/ r "patt_file.txt"" test.txt
