双重引用论证的高管 [英] exec with double quoted argument

问题描述

我想用 exec 包来执行 find Windows命令，但是windows正在做一些奇怪的转义。

我有类似的东西：

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


但是这是抛出错误，因为Windows将它转换为

find / SomeText


有人知道为什么吗？我如何执行使用exec包在windows上找到？

谢谢！

解决方案

好的，这可能比您预想的要复杂一些，但 是一个解决方案：

  package main 
 
 $（
fmt
os / exec
系统调用
）
 
 func main（）{
 cmd：= exec.Command（`find`）
 cmd.SysProcAttr =& syscall.SysProcAttr {} 
 cmd.SysProcAttr.CmdLine = `找到SomeTexttest.txt` 
 out，err：= cmd.Output（） 
 fmt.Printf（％s \ n，out）
 fmt.Printf（％v \ n，err）
} 
  

不幸的是，尽管对此的支持已于2011年添加，但似乎未将其纳入文档呢。 （虽然也许我只是不知道在哪里看。）

I want to execute find Windows command using exec package, but windows is doing some weird escaping.

I have something like: out, err := exec.Command("find", `"SomeText"`).Output()

but this is throwing error because Windows is converting this to find /SomeText"

Does anyone know why? How I can execute find on windows using exec package?

Thanks!

解决方案

OK, it's a bit more complicated than you might have expected, but there is a solution:

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)
}

Unfortunately, although support for this was added in 2011, it doesn't appear to have made it into the documentation yet. (Although perhaps I just don't know where to look.)
