How can I add string to the end of the file without line break?

Answer 1

You can use the -n parameter of echo. Like this:

$ touch a.txt
$ echo -n "A" >> a.txt
$ echo -n "B" >> a.txt
$ echo -n "C" >> a.txt
$ cat a.txt
ABC

EDIT: Aha, you already had a file containing string and newline. Well, I'll leave this here anyway, might we useful for someone.
