I created two files:
echo -e "1\n2\n3\n4\n5" > 123.txt echo -e "a\nb\nc\nd\ne" > abc.txt
I want to get the file
123.txt with the following contents:
1 2 3 b c d 4 5
So in other words insert the rows with numbers from 2 to 4 of the file
abc.txt into the file
123.txt after the third line.
I have reviewed the many similar questions here, but did not find a suitable answer. Nevertheless I got the lines:
sed -n '2,4p' abc.txt
and put some text into the file after the third line:
sed -i '3a\mytext' 123.txt
How to do this using the previous command stdout or/and a
awk single command?
