I have a VM that I want to delay 15 seconds so it can connect to Wi-Fi.
I use the session settings app on XFCE like this: “vboxmanage startvm ubuntu-20.04.3-live-server-amd64 --type headless”
What argument delays the program for 15 seconds? Instead of immediately.
Explanation: sleep is a pause or rest … with the numerical argument being amount of time.
In this case ‘rest for 15 seconds’ && is to mean ‘if the previous command finished successfully, then do this next thing’.
So we have ‘wait for 15 seconds and then do [your commands]’.
