How to use golang to set hidden attributes of files (folders)

In programming development, sometimes it is necessary to set files or folders to a hidden state to protect or prevent misoperation. Therefore, in golang, we can set the hidden attributes of files or folders through some methods. This article will introduce in detail how to set file or folder hidden attributes in golang.

1. Use of OS packages

In golang, you can easily get or set the attributes of files or folders through the use of OS packages, including hidden attributes. The specific steps are as follows:

1. Obtain file information

First, you need to use the Stat() function in the OS package to obtain file information, and then obtain the file attributes through the FileInfo object.

fileInfo, err := os.Stat("test.txt")
if err != nil {
    fmt.Println(err)
}

2. Set file attributes

The file permissions and other attributes can be obtained through the Mode() method of the Fileinfo object, in which hidden attributes can be set. The file can be hidden by overriding the Mode() method of the file.

err = os.Chmod("test.txt", fileInfo.Mode()|os.ModeHidden)
if err != nil {
    fmt.Println(err)
}

Note: The permissions and attribute information obtained through the Mode() method is an int type value, so bit operations are required to modify it.

3. Cancel file hiding

By canceling file hiding method, just clear the hidden bit in the file attribute.

err = os.Chmod("test.txt", fileInfo.Mode()&^os.ModeHidden)
if err != nil {
    fmt.Println(err)
}

In the above steps, we obtain file information by using the Stat() method in the OS package, and then set the file attributes using the Chmod() method. At the same time, the hidden attributes of the file can be easily operated through code, such as the operation of the test.txt file.

2. Use the syscall package to hide files

In addition to using the OS package, we can also directly call windows through the syscall package to hide files.

syscall.SetFileAttributes(syscall.StringToUTF16Ptr("test.txt"), syscall.FILE_ATTRIBUTE_HIDDEN)

This method can directly set the test.txt file as a hidden attribute.

syscall.SetFileAttributes(syscall.StringToUTF16Ptr("test.txt"), syscall.FILE_ATTRIBUTE_NORMAL)

Similarly, we can use the syscall package to cancel the hidden attributes of the file. The above two methods are relatively simple to implement, but programmers who are familiar with operating system related knowledge can find that using syscall can get more control and be more flexible.

Summary

This article explains in detail how to set the hidden attributes of files or folders in golang by introducing the use of OS packages and syscall packages. These methods can easily hide and unhide files or folders, and are very suitable for system development with high confidentiality requirements.
