闲的无聊贴个显示/隐藏文件的代码，因为经常要用

package main

import (
    "fmt"
    "os"
    "strings"
    "os/exec"
)

func show()  {
    cmd := exec.Command("/bin/bash","-c","defaults write com.apple.finder AppleShowAllFiles -boolean true ; killall Finder")
    _, err := cmd.Output()
    if err != nil {
        fmt.Println("运行失败: " + err.Error())
        return
    }else {
        fmt.Println("运行成功")
    }
}

func hide()  {
    cmd := exec.Command("/bin/bash","-c","defaults write com.apple.finder AppleShowAllFiles -boolean false ; killall Finder")
    _, err := cmd.Output()
    if err != nil {
        fmt.Println("运行失败: " + err.Error())
        return
    }else {
        fmt.Println("运行成功")
    }
}

func main() {

    argNum := len(os.Args)
    if argNum == 1{
        fmt.Println("缺少参数, show或hide")
        return
    }

    shouldShow := os.Args[1]

    if strings.EqualFold("show",shouldShow){
        show()
    }
    if strings.EqualFold("hide",shouldShow){
        hide()
    }
}
