如何在 Windows/Mac/Linux 中创建隐藏文件?
How to create a hidden file in Windows/Mac/Linux?
我构建了一个控制台应用程序,需要创建一些隐藏文件。
我也知道以点开头的文件名将隐藏在 Linux 和 mac 中,但是 windows?
设置文件属性?
有没有办法在 Windows / Linux / Mac 中创建隐藏文件和目录?
Windows:
Sets the attributes for a file or directory.
FILE_ATTRIBUTE_HIDDEN 2 (0x2)
The file or directory is hidden. It is not included in an ordinary
directory listing.
开始:
func SetFileAttributes(name *uint16, attrs uint32) (err error)
从 Go UTF-8 编码字符串 (string
) 转换为 Windows UTF-16 编码字符串指针 (*uint16
)。
func UTF16PtrFromString(s string) (*uint16, error)
UTF16PtrFromString returns pointer to the UTF-16 encoding of the UTF-8
string s, with a terminating NUL added. If s contains a NUL byte at
any location, it returns (nil, EINVAL).
使用OSBuild Contraints.
例如,
hide/attrib.go
:
package main
import (
"fmt"
"io/ioutil"
"os"
)
func main() {
filename := `test.hidden.file`
os.Remove(filename)
os.Remove("." + filename)
err := ioutil.WriteFile(filename, []byte(filename), 0666)
if err != nil {
fmt.Fprintln(os.Stderr, err)
return
}
err = HideFile(filename)
if err != nil {
fmt.Fprintln(os.Stderr, err)
return
}
fmt.Println("hidden:", filename)
}
hide/hide.go
:
// +build !windows
package main
import (
"os"
"path/filepath"
"strings"
)
func HideFile(filename string) error {
if !strings.HasPrefix(filepath.Base(filename), ".") {
err := os.Rename(filename, "."+filename)
if err != nil {
return err
}
}
return nil
}
hide/hide_windows.go
:
// +build windows
package main
import (
"syscall"
)
func HideFile(filename string) error {
filenameW, err := syscall.UTF16PtrFromString(filename)
if err != nil {
return err
}
err = syscall.SetFileAttributes(filenameW, syscall.FILE_ATTRIBUTE_HIDDEN)
if err != nil {
return err
}
return nil
}
输出(Linux):
$ tree hide
hide
├── attrib.go
├── hide.go
└── hide_windows.go
$
$ go build && ./hide
hidden: test.hidden.file
$ ls -a .test.hidden.file
.test.hidden.file
$
输出(Windows):
>go build && hide

>attrib test.hidden.file
A H \test.hidden.file

import (
_ "golang.org/x/sys/windows"
"os"
"runtime"
"syscall"
)
func HideFile(filename string) (status bool, err error) {
if runtime.GOOS == "windows" {
filenameW, err := syscall.UTF16PtrFromString(filename)
if err != nil {
return false, err
}
err = syscall.SetFileAttributes(filenameW, syscall.FILE_ATTRIBUTE_HIDDEN)
if err != nil {
return false, err
}
} else {
if filename[0:1] != "." {
err = os.Rename(filename, "." + filename)
if err != nil {
return false, err
}
}
}
return true, nil
}
这是我的代码。但是无法在Linux中构建。
错误:
src/util/hidden.go:12:21: undefined: syscall.UTF16PtrFromString
src/util/hidden.go:17:9: undefined: syscall.SetFileAttributes
src/util/hidden.go:17:46: undefined: syscall.FILE_ATTRIBUTE_HIDDEN
我为此制作了一个跨平台模块(可在此处获得:higgs)。
您只需调用 Hide
或 Unhide
函数即可隐藏或取消隐藏文件或目录。
示例代码:
package main
import (
"fmt"
"github.com/dastoori/higgs"
)
func main() {
err := higgs.Hide("foo.txt")
if err != nil {
fmt.Println(err)
}
}
制作这样的文件:
//go:generate mkwinsyscall -output zhide.go hide.go
//sys setFileAttributes(name string, attr int) (err error) = kernel32.SetFileAttributesW
package main
const (
file_attribute_hidden = 2
file_attribute_normal = 128
)
func main() {
setFileAttributes("file.txt", file_attribute_hidden)
}
然后构建:
go mod init hide
go mod tidy
go generate
go build
