Run command `at ` 5 seconds from now

Question

As part of a slightly complex script, I need to tell a server to run a simulation. Normally, I would achieve this by doing ssh user@server \'simulation/script\'

Answer 1

Redirecting stdin/stdout/stderr in addition to backgrounding the script will allow the SSH session to close immediately after executing the backgrounded command:

ssh hostname "/path/to/script /dev/null 2>/dev/null &"
