how to use virtualbox for shell scripting

You can use the RunShellScript command to run any custom script that you want. This table shows the list of commands available for Linux VMs. If you're blocking traffic on the virtual machine, you can use service tags to allow traffic to Azure public IP addresses by using the AzureCloud tag. If the extension doesn't have access to these endpoints, the scripts might run successfully but not return the results. To function correctly, Run Command requires connectivity (port 443) to Azure public IP addresses.

Outbound connectivity from the VM is required to return the results of the script.

The maximum time a script can run is 90 minutes.

Scripts that prompt for information (interactive mode) aren't supported.

Scripts run by default as an elevated user on Linux.

The minimum time to run a script is about 20 seconds.

Output is limited to the last 4,096 bytes.

The following restrictions apply when you're using Run Command: It's one of the only ways to troubleshoot and remediate a virtual machine that doesn't have the RDP or SSH port open because of network or administrative user configuration. This capability is useful in all scenarios where you want to run a script within a virtual machine. You use Run Command through the Azure portal, REST API, or Azure CLI for Linux VMs.

Run Command can run scripts on your virtual machines remotely by using the VM agent. You can access your virtual machines in multiple ways. They can help you to quickly diagnose and remediate VM access and network issues and get the VM back to a good state. You can use these scripts for general machine or application management. The Run Command feature uses the virtual machine (VM) agent to run shell scripts within an Azure Linux VM. Applies to: ✔️ Linux VMs ✔️ Flexible scale sets
