The command "kubectx -" is used to list the available contexts or switch between contexts in Kubernetes.

In Kubernetes, a context represents a cluster, user credentials, and a namespace. It allows you to interact with different clusters or namespaces without needing to constantly modify your Kubernetes configuration. The "kubectx" command helps you manage these contexts.

When you run "kubectx -" (with a hyphen after the command), it lists all the available contexts in your Kubernetes configuration. It provides a list of context names that you can use to identify different clusters or namespaces.

For example, if you have multiple contexts defined for different clusters (e.g., "my-cluster-1" and "my-cluster-2"), running "kubectx -" would display these context names:

my-cluster-1
my-cluster-2

You can then use the context name to switch to a specific context using the "kubectx" command, like:

kubectx my-cluster-1

This will set the current context to "my-cluster-1", enabling you to interact with that cluster.

Overall, "kubectx -" helps you view the available contexts in your Kubernetes configuration, making it easier to manage and switch between different clusters or namespaces.
