How to Pass Double-Quoted Arguments to Windows Commands Using Go's `exec` Package?

Executing Windows Commands with Double-Quoted Arguments

When executing Windows commands using the exec package, certain characters in the argument string require special handling due to the way Windows interprets double quotes. This article investigates why this occurs and provides a solution to overcome this issue.

By default, Windows interprets double quotes within an argument string as the beginning of a new argument. This becomes problematic when you want to pass an argument that contains spaces, as Windows will split the argument into multiple parts. For example, executing the following command will fail:

exec.Command("find", `"SomeText"`).Output()
Copy after login

This is because Windows will interpret the double-quoted argument as two separate arguments: find and SomeText".

Solution:

To execute a Windows command with a double-quoted argument, you need to use the CmdLine field in syscall.SysProcAttr, as shown below:

<code class="go">cmd := exec.Command(`find`)
cmd.SysProcAttr = &amp;syscall.SysProcAttr{}
cmd.SysProcAttr.CmdLine = `find "SomeText" test.txt`
out, err := cmd.Output()
fmt.Printf("%s\n", out)
fmt.Printf("%v\n", err)</code>
Copy after login

By setting CmdLine, you can specify the exact command line that will be executed by Windows, bypassing the default argument parsing. This ensures that the double-quoted argument is treated as a single argument.
