Shell Script error

[skyguy126]

I am trying to make a simple shell script and I am getting constant errors.
So i made a test.sh file and saved it in /data because /sdcard is excuetable protected.
The shell file contains:
#!/system/bin/sh
cd /sdcard
mkdir test
su -c "rm /data/test.sh"
echo Done!

So then I typed the command chmod 777 /data/test.sh

I also tried chown root:shell /data/test.sh
And then /data/test.sh and it returned: tmp-mksh: /data/test.sh: No such file or directory
So then I tried running: sh /data/test.sh and it returned:
No such file or directoryrd
Done
I even tried executing the script from a root shell interface but still no luck same result as above.

Forgot to mention I am running 4.4.4 on a moto g that is rooted and has busybox installed.
