This question already has an answer here:
I know how to replace a line with another line or several other lines with tools like
sed. But is there an easy way, to replace a line in a file with the whole content of a second file?
So, let's have an example. I have a file called
A 1 B 2 C 3
And I have a second file
line 1 line 2 line 3
Now, I want to replace
line 2 with the whole content of
file1.txt, so in the end, it should look like this
line 1 A 1 B 2 C 3 line 3
One way I could think about would be something like this:
sed -i "s/line 2/$(cat file1.txt)/g" file2.txt.
But then I also have to check some special characters like
/ and maybe more. I have to assume, that every possible readable character could be in
So, back to my question: Is there an easy way, to replace a line in a file with the whole content of a second file? It doesn't have to be
sed. It could be also another tool, if it could do the job better...
