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?
Regards,
Venkat
If you look at the output of od -c, you'll notice that it has a backslash followed by an n, with a space between them. Then a \n with no space.
If you want to literally append a newline character to a file, use the -e flag to echo.
$ echo "1\n" > a.txt
$ echo -e "1\n" > b.txt
$ wc -c a.txt
4 a.txt
$ wc -c b.txt
3 b.txt
