how to remove new line in bash using echo

[packets]

I created a simple bash script. My primary concern is how to remove the new line in the output of my script in /root/test.txt

Synopsis

./script.sh foo fee

Content

case $1 in
*)
echo -ne "
$1
$2" > /root/test.txt

The output of this is

foo
fee

I want to remove the new line above the foo. Is it possible?

Problem fixed.

I didn't notice the '"' that it should follow $1 and forgot to remove remove -e

[packets]

forgot to ask this.

Can I make it short that instead of writing

case $1 in
*)
echo -ne "
$1
$2 $3 $4 $5 $6 $7 $8 $9" > /root/test.txt

Is there a way I can shortened the portion $2 $3 $4 $5 $6 $7 $8 $9 up to variable I want let's say $100.

I though $[2-100] is ok but instead it do an arithmetic which was $98.

for((i=2;$i<$#;i++)) do echo -n "$i "; done > /root/test.txt

can this line do it ?
