I am looking for to execute the shell script through ssh. Getting error as File not found: ''

  1. $ssh -i key.pem root@ -C "sh /root/myScript.sh"
    Output: File not found: ''

  2. $ssh -i key.pem root@ -C "/bin/sh ec2-create-volume --size 10 --availability-zone us-east-1a"
    Output: File not found: ''

Note:

  1. I have read write permission to my remote machine script myScript.sh
  2. I can able to manually execute the command "ec2-create-volume --size 10 --availability-zone us-east-1a" successfully
    If i want to execute the same with ssh via script, how i should procede. Please help me on this.

What may be the issues ?
