如何为go bin提供命令

Question

我使用以下代码创建应根据cli传递的一些标志运行的命令。

我使用眼镜蛇回购 https://github.com/spf13/cobra

当我运行它 go run main.go echo test

我懂了

Print: test

哪个有效。

现在，我运行go install打开bin目录，然后单击文件newApp（这是我的应用程序的名称）

它打印

Usage:
  MZR [command]

Available Commands:
  echo        Echo anything to the screen
  help        Help about any command
  print       Print anything to the screen

Flags:
  -h, --help   help for MZR

Use "MZR [command] --help" for more information about a command.


[Process completed]

而且我不使用MZR echo在本地运行时可以使用的任何命令（例如）go run main.go echo test

但是我想像 下面 那样使用它，MZR -h 或者MZR echo，我该怎么做？（并将我在go install- 之后创建的bin中的文件也提供给我的朋友Unix executable - 3.8 MB）

例如，像这个仓库一样，它使用相同的命令行工具并运行它，您可以使用hoarder --server https://github.com/nanopack/hoarder

例如，这是代码（使其更简单）

package main

import (
    "fmt"
    "strings"

    "github.com/spf13/cobra"
)

func main() {
    var echoTimes int

    var cmdPrint = &cobra.Command{
        Use:   "print [string to print]",
        Short: "Print anything to the screen",
        Long: `print is for printing anything back to the screen.
For many years people have printed back to the screen.`,
        Args: cobra.MinimumNArgs(1),
        Run: func(cmd *cobra.Command, args []string) {
            fmt.Println("Print: " + strings.Join(args, " "))
        },
    }

    var cmdEcho = &cobra.Command{
        Use:   "echo [string to echo]",
        Short: "Echo anything to the screen",
        Long: `echo is for echoing anything back.
Echo works a lot like print, except it has a child command.`,
        Args: cobra.MinimumNArgs(1),
        Run: func(cmd *cobra.Command, args []string) {
            fmt.Println("Print: " + strings.Join(args, " "))
        },
    }

    var cmdTimes = &cobra.Command{
        Use:   "times [# times] [string to echo]",
        Short: "Echo anything to the screen more times",
        Long: `echo things multiple times back to the user by providing
a count and a string.`,
        Args: cobra.MinimumNArgs(1),
        Run: func(cmd *cobra.Command, args []string) {
            for i := 0; i < echoTimes; i++ {
                fmt.Println("Echo: " + strings.Join(args, " "))
            }
        },
    }

    cmdTimes.Flags().IntVarP(&echoTimes, "times", "t", 1, "times to echo the input")

    var rootCmd = &cobra.Command{Use: "MZR"}
    rootCmd.AddCommand(cmdPrint, cmdEcho)
    cmdEcho.AddCommand(cmdTimes)
    rootCmd.Execute()
}

可执行文件的名称取自目录名称。将目录重命名newApp为MZR。进行此更改后，该go install命令将创建一个名为的可执行文件MZR。如果可执行文件在您的路径上，则可以使用MZR -h或从命令行运行它MZR echo。
