Question

I am trying to start a script with cloud-init on a ubuntu 11.10 ec2 instance.

I put the script script.sh in the folder /var/lib/cloud/scripts/per-boot.
Content of script.sh is simple:

#/!/bin/sh 
echo "test"

After a reboot, I get the following error:

run-parts: failed to exec /var/lib/cloud/scripts/per-boot/script.sh: Exec format error
run-parts: /var/lib/cloud/scripts/per-boot/script.sh exited with return code 1

Any ideas how to fix it?

Answer 1

I believe your problem is related to the fact that #/!/bin/sh is not a valid input type. Need to remove the / after the #.

#!/bin/sh 
echo "test"

Let me know if you still see the problems after this.
