[英]exec.Command().Run() not executing command properly in Windows
I have a linting utility called config-lint: https://github.com/stelligent/config-lint which I downloaded for windows.我有一个名为 config-lint 的 linting 实用程序: https : //github.com/stelligent/config-lint ,我为 Windows 下载了它。
I downloaded it and added it to the path and able to run it as seen below我下载了它并将其添加到路径中并能够运行它,如下所示
E:\>config-lint -terraform config-lint-master\example-files\config [ {
"AssertionMessage": "None expression fails: ",
"Category": "resource",
"CreatedAt": "2020-10-02T10:23:19Z",
"Filename": "config-lint-master\\example-files\\config\\s3.tf",
"LineNumber": 43,
"ResourceID": "bucket_with_not",
"ResourceType": "aws_s3_bucket_policy",
"RuleID": "S3_NOT_ACTION",
"RuleMessage": "Should not use NotAction in S3 bucket policy",
"Status": "WARNING" }, {
"AssertionMessage": "Not expression fails",
"Category": "resource",
"CreatedAt": "2020-10-02T10:23:19Z",
"Filename": "config-lint-master\\example-files\\config\\security_group.tf",
"LineNumber": 1,
"ResourceID": "allow_all",
"ResourceType": "aws_security_group",
"RuleID": "SG_INGRESS_ALL_PROTOCOLS",
"RuleMessage": "Best practices recommend not opening all protocols and ports to ingress traffic",
"Status": "WARNING" },
--- more output to follow --- 更多输出
I wish to achieve the same via the exec package in go Lang.我希望通过 go Lang 中的 exec 包实现相同的目标。 Below is my code
下面是我的代码
args := []string{"-terraform", "E:\\config-lint-master\\example-files\\config"}
app := "config-lint"
cmd := exec.Command(app, args...)
//cmd := exec.Command("config-lint", "-terraform", "E:\\config-lint-master\\example-files\\config")
cmd.Stdout = &bytes.Buffer{}
cmdOp := &bytes.Buffer{}
cmd.Stdout = cmdOp
err := cmd.Run()
if err != nil {
fmt.Println("Error->", err)
} else {
fmt.Println(cmdOp)
}
On executing this, I get the error as在执行此操作时,我收到错误消息
Error-> exit status 4294967295错误->退出状态 4294967295
I have no idea what this means, I'm new to Go Lang.我不知道这意味着什么,我是 Go Lang 的新手。
Note: When I run it using the below by passing a file name at the end, it then executes.注意:当我通过在最后传递文件名使用以下命令运行它时,它会执行。 It doesn't seem to be working when a directory is passed.
传递目录时它似乎不起作用。
args := []string{"-terraform", "E:\\config-lint-master\\example-files\\config\\elb.tf"}
config-lint can be run as below config-lint 可以如下运行
config-lint -terraform <FILE_OR_DIRECTORY_OF_TF_FILES> config-lint -terraform <FILE_OR_DIRECTORY_OF_TF_FILES>

Go Lang Version: go version go1.14.6 windows/amd64 Golang 版本:go 版本 go1.14.6 windows/amd64

The issue is that for some reason, that command fails even in shell setting.问题是,由于某种原因,即使在 shell 设置中,该命令也会失败。 So what I did was, ignore the error unless the output is empty:
所以我所做的是,除非输出为空,否则忽略错误:
package main
import (
"fmt"
"log"
"os/exec"
)
func main() {
o := exec.Command(
"config-lint", "-terraform", "config-lint-master/example-files/config",
)
y, e := o.Output()
if len(y) == 0 {
log.Fatal(e)
}
fmt.Printf("%s", y)
}
or you can just output directly to console:或者你可以直接输出到控制台:
package main
import (
"os"
"os/exec"
)
func main() {
o := exec.Command(
"config-lint", "-terraform", "config-lint-master/example-files/config",
)
o.Stdout = os.Stdout
o.Run()
}
