英文:
Get file inode in Go
问题
如何在Go中获取文件的inode?
我已经可以像这样打印它:
file := "/tmp/system.log"
fileinfo, _ := os.Stat(file)
fmt.Println(fileinfo.Sys())
fmt.Println(fileinfo)
查看Go的实现,很明显要找一些stat
方法,但我仍然没有找到Unix系统的结构定义。
如何直接获取inode值?
源代码中哪个文件定义了Sys()
的结构?
英文:
How can I get a file inode in Go?
I already can print it like this:
file := "/tmp/system.log"
fileinfo, _ := os.Stat(file)
fmt.Println(fileinfo.Sys())
fmt.Println(fileinfo)
Looking at Go implementation it was obvious looking for some stat
method, but I still did not manage to find the structure definition for a Unix system.
How can I get the inode value directly?
Which file/s in the source code define the structure of Sys()
?

你可以使用类型断言来从fileinfo中获取底层的syscall.Stat_t
,代码如下:
package main
import (
"fmt"
"os"
"syscall"
)
func main() {
file := "/etc/passwd"
fileinfo, _ := os.Stat(file)
fmt.Printf("fileinfo.Sys() = %#v\n", fileinfo.Sys())
fmt.Printf("fileinfo = %#v\n", fileinfo)
stat, ok := fileinfo.Sys().(*syscall.Stat_t)
if !ok {
fmt.Printf("Not a syscall.Stat_t")
return
}
fmt.Printf("stat = %#v\n", stat)
fmt.Printf("stat.Ino = %#v\n", stat.Ino)
}
希望对你有帮助!
英文:
You can use a type assertion to get the underlying syscall.Stat_t
from the fileinfo like this
package main
import (
"fmt"
"os"
"syscall"
)
func main() {
file := "/etc/passwd"
fileinfo, _ := os.Stat(file)
fmt.Printf("fileinfo.Sys() = %#v\n", fileinfo.Sys())
fmt.Printf("fileinfo = %#v\n", fileinfo)
stat, ok := fileinfo.Sys().(*syscall.Stat_t)
if !ok {
fmt.Printf("Not a syscall.Stat_t")
return
}
fmt.Printf("stat = %#v\n", stat)
fmt.Printf("stat.Ino = %#v\n", stat.Ino)
}

你可以执行以下操作:
file := "/tmp/system.log"
var stat syscall.Stat_t
if err := syscall.Stat(file, &stat); err != nil {
panic(err)
}
fmt.Println(stat.Ino)
其中 stat.Ino
是你要查找的 inode。
英文:
You can do the following:
file := "/tmp/system.log"
var stat syscall.Stat_t
if err := syscall.Stat(file, &stat); err != nil {
panic(err)
}
fmt.Println(stat.Ino)
Where stat.Ino
is the inode you are looking for.

包syscall现已弃用。请参阅https://pkg.go.dev/golang.org/x/sys。
英文:
Package syscall is now deprecated. See https://pkg.go.dev/golang.org/x/sys instead.
