Go 调用交互式shell

本文的代码已上传到github

cmdlineps -ef

举个🌰

#!/bin/bash

read -s -p "Enter Password: "  pwd
echo -e "\nYour password is: " $pwd

go调用交互式shell代码样例如下

func TestCallInteractiveShell(t *testing.T) {
    dir, err := os.Getwd()
    if err != nil {
        panic(err)
    }
    cmd := exec.Command("/bin/bash", dir+"/interactive_shell.sh")
    var stdout, stderr bytes.Buffer
    cmd.Stdout = &stdout
    cmd.Stderr = &stderr
    buffer := bytes.Buffer{}
    buffer.Write([]byte("ZhangJian"))
    cmd.Stdin = &buffer
    err = cmd.Run()
    if err != nil {
        panic(err)
    }
    outStr, errStr := string(stdout.Bytes()), string(stderr.Bytes())
    fmt.Println("output is ", outStr)
    fmt.Println("err output is ", errStr)
    fmt.Println("Execute Over")
}

输出结果

=== RUN   TestCallInteractiveShell
output is  Your password is:  ZhangJian

err output is  
Execute Over
--- PASS: TestCallInteractiveShell (0.00s)
PASS
