Need to add a numeric & special char to end of the first line
Existing file:

Hello Joselouis,
Welcome to forums, hope you will enjoy learning and sharing knowledge and learning here. Could you please try following as a starting point and let me know if this helps you.
Where variable named s1have the value of " and it will provide the output as follows.
Output will be as follows. NOTE: Though we could use -ioption of sed but it is not good practice to use it with large size files, it is better to use redirect option of standard output to a temp file and then rename it to the orginal Input_file.
Thanks,
R. Singh

Hi,
I want to add \n as a EOF at the end of file if it does't exist in a single command. How to do this?
when I use command
echo "1\n" > a.txt
and
od -c a.txt
0000000 1 \n \n
0000003
How does it differentiate \n and eof in this case?
