How to Execute Commands with Double Quoted Arguments in Go\'s Exec Package on Windows?

Executing Command with Double Quoted Argument in Exec Package for Windows

Executing commands using the exec package requires careful attention when dealing with double-quoted arguments, especially in Windows environments. This article delves into a peculiar issue involving the find command and provides a solution for executing it correctly.

The issue arises when trying to execute a command like:

out, err := exec.Command("find", `"SomeText"`).Output()

On Windows, this command fails due to the double quotes causing the argument to be escaped as:

find /SomeText"

To resolve this, a more complex approach is necessary, as demonstrated by the following code:

<code class="go">package main

import (
    "fmt"
    "os/exec"
    "syscall"
)

func main() {
    cmd := exec.Command(`find`)
    cmd.SysProcAttr = &syscall.SysProcAttr{}
    cmd.SysProcAttr.CmdLine = `find "SomeText" test.txt`
    out, err := cmd.Output()
    fmt.Printf("%s\n", out)
    fmt.Printf("%v\n", err)
}</code>

In this code, we:

• Set the SysProcAttr field of the cmd to customize the process attributes.
• Use the CmdLine field to specify the exact command line to execute, including the quoted argument.

This approach allows us to execute the find command with a double-quoted argument as intended. However, it's worth noting that this behavior is not explicitly documented in the Go documentation, indicating that it may not be a widely known feature.
