Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system.”

A block of code is set as follows:

func init() {
    audioCmd.Flags().StringP("filename", "f", "", "audio
      file")
    uploadCmd.AddCommand(audioCmd)
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

var (
    Filename = ""
)
func init() {
    uploadCmd.PersistentFlags().StringVarP(&Filename,
      "filename", "f", "", "file to upload")
    rootCmd.AddCommand(uploadCmd)
}

Any command-line input or output is written as follows:

cobra-cli add upload audio [-f|--filename]
  audio/beatdoctor.mp3

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Select System info from the Administration panel.”
