# The following command gets the SSH public keys authorized to connect to the VM by adding a query:

az vm show --resource-group rg-demo1 --name vm1 --query "osProfile.linuxConfiguration.ssh.publicKeys"

# To get multiple values, put expressions separated by commas in square brackets [ ] (a multiselect list)

az vm show --resource-group rg-demo1 --name TestVM --query "[name, osProfile.adminUsername, osProfile.linuxConfiguration.ssh.publicKeys[0].keyData]"

# To get a dictionary instead of an array when querying for multiple values, use the { } (multiselect hash) operator.

# To access the properties of elements in an array, you do one of two operations: flattening or filtering. Flattening an array is done with the [] JMESPath operator. All expressions after the [] operator are applied to each element in the current array. If [] appears at the start of the query, it flattens the CLI command result.

az vm list --resource-group rg-demo1 --query "[].{Name:name, OS:storageProfile.osDisk.osType, admin:osProfile.adminUsername}"
