Hi, I hope this is the right place to ask this 
I’m running an AWS AMI based off ubuntu-bionic-18.04-amd64-server- which comes bundled with a snap called “aws”.
I also have some bash scripts running on boot, which I believe run at the same time snap is getting setup (in parallel).
One of my scripts executes /snap/bin/aws, which intermittently fails with the message:
error: unknown command “s3”, see ‘snap help’
I believe there is a race condition between the bash scripts I am running on startup and the availability of the snap aws binary.
If I put a sleep in my script, or call /snap/bin/aws later on, say after 30 seconds, then this is not an issue, it works perfectly.
My question: is there a way I can wait for snaps to be available before running scripts which depend on them?
Thanks!
