How to Execute Commands with Double-Quoted Arguments on Windows Using the exec Package?

Executing a Command with a Double-Quoted Argument on Windows

When using the exec package to execute commands with double-quoted arguments on Windows, Windows may interpret the quotation marks as commands instead of delimiters. This can lead to unexpected behavior and errors.

For instance, the following code snippet attempts to execute the find command with a double-quoted argument:

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

However, on Windows, this will result in the following command being executed:

find /SomeText"

The quotation marks are interpreted as part of the command, rather than delimiting the argument.

To resolve this issue and correctly execute the find command on Windows using the exec package, the following approach can be used:

<code class="go">package main

import (
    "fmt"
    "os"
    "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, the SysProcAttr field is used to explicitly set the command line for the process. By setting the CmdLine field to find "SomeText" test.txt, the command is executed with the double-quoted argument intact.

This approach allows double-quoted arguments to be passed correctly to the command, resulting in the desired execution on Windows.
