var CmdCompletion = &cobra.Command{
	Use:   "completion [bash|zsh|fish|powershell]",
	Short: "Generate completion script for a shell",
	Long: `To load completions:

Bash:

$ source <(carrier completion bash)

# To load completions for each session, execute once:
Linux:
  $ carrier completion bash > /etc/bash_completion.d/carrier
MacOS:
  $ carrier completion bash > /usr/local/etc/bash_completion.d/carrier

ATTENTION:
    The generated script requires the bash-completion package.
    See https://kubernetes.io/docs/tasks/tools/install-kubectl/#enabling-shell-autocompletion
    for information on how to install and activate it.

Zsh:

# If shell completion is not already enabled in your environment you will need
# to enable it.  You can execute the following once:

$ echo "autoload -U compinit; compinit" >> ~/.zshrc

# To load completions for each session, execute once:
$ carrier completion zsh > "${fpath[1]}/_carrier"

# You will need to start a new shell for this setup to take effect.

Fish:

$ carrier completion fish | source

# To load completions for each session, execute once:
$ carrier completion fish > ~/.config/fish/completions/carrier.fish

Powershell:

PS> carrier completion powershell | Out-String | Invoke-Expression

# To load completions for every new session, run:
PS> carrier completion powershell > carrier.ps1
# and source this file from your powershell profile.
