How Do I Get the User's Home Directory in Go?

Obtaining User Home Directory in Go

Querying a user's home directory is a common task in programming. In Go, accessing this information has evolved over different versions.

Recommended Approach

Since Go 1.12, the preferred method is to utilize the os.UserHomeDir function:

import (
    "fmt"
    "log"
    "os"
)

func main() {
    dirname, err := os.UserHomeDir()
    if err != nil {
        log.Fatal(err)
    }
    fmt.Println(dirname)
}

Legacy Recommendation (Go 1.0.3)

Prior to Go 1.12, the recommended approach involved using the user.Current function from the os/user package:

import (
    "fmt"
    "log"
    "os/user"
)

func main() {
    usr, err := user.Current()
    if err != nil {
        log.Fatal(err)
    }
    fmt.Println(usr.HomeDir)
}

Cross-Platform Compatibility

Both os.UserHomeDir and user.Current are documented to work on the following platforms:

• Linux
• Windows
• Darwin (macOS)
• OpenBSD
• NetBSD
• FreeBSD
• Plan 9
• Solaris
• AIX
