列出目录中按创建时间排序的文件

Question

I know how to list the files in a directory using ioutil.ReadDir()... but how do I sort them by creation time (from oldest to newest)? I'm using go 8.3.

Answer 1

On Linux you cannot, and Go has nothing to do with it (creation time is simply not stored in most Linux file systems). On Windows you can, but not with the go standard library. Well, it may be possible with the value returned by (os.FileInfo).Sys(), but you would be better served to look for a library.

Sorting by the last modified time is fairly easy:

files, err := ioutil.ReadDir(path)
// TODO: handle the error!
sort.Slice(files, func(i,j int) bool{
    return files[i].ModTime().Before(files[j].ModTime())
})
