You can enter a new line like this.

echo "\n"

echo "X1 02:12:13\nX2 03:02:12"

Actually, not all versions of echo permit backslash escape codes, but all versions of the shell should allow newlines inside quoted strings.

echo "X1 02:12:13
X2 03:02:12"

Yup, that's a newline smack dab in the middle of the quoted string.

Pass the -e parameter to enable interpretation of backslash escapes(which us off by default). Like this:

echo -e "hello\nworld!"

The -e option is not standard. A POSIX-compliant echo does not accept any options:

$ echo -e "12 34\n56 78"
-e 12 34\n56 78

The simplest and most portable way is to use printf:

string="12 34\n56 78"
printf "%b\n" "$string"
