Java 如何使用process builder读取read shell命令的输入消息

我试图使用process builder执行一个shell脚本。shell脚本使用“read”shell命令。但是当我检查shell脚本的输出流时，与“read”命令关联的输入消息丢失了。 shell脚本如下所示：

    #!/bin/bash
    # script.sh
    # This scripts has an input argument
    echo Hello World
    read -p "Enter something: " val1
    echo First Name: $val1
    read -p "Enter something: " val2
    echo Last Name: $val2
    echo $val1 $val2 invoked $1
    echo  $1 "completed successfully"

    Hello World
    Enter something: albin
    First Name: albin
    Enter something: suresh
    Last Name: suresh
    albin suresh invoked install
    install completed successfully

    Hello World
    First Name: albin
    Last Name: suresh
    albin suresh invoked install
    install completed successfully

当我使用命令手动运行此脚本时

    ./script.sh install

终端上的输出如下所示：

    #!/bin/bash
    # script.sh
    # This scripts has an input argument
    echo Hello World
    read -p "Enter something: " val1
    echo First Name: $val1
    read -p "Enter something: " val2
    echo Last Name: $val2
    echo $val1 $val2 invoked $1
    echo  $1 "completed successfully"

    Hello World
    Enter something: albin
    First Name: albin
    Enter something: suresh
    Last Name: suresh
    albin suresh invoked install
    install completed successfully

    Hello World
    First Name: albin
    Last Name: suresh
    albin suresh invoked install
    install completed successfully

但是，当我使用process builder运行相同的命令时，输出中缺少“Enter something”命令。我得到的结果如下：

    #!/bin/bash
    # script.sh
    # This scripts has an input argument
    echo Hello World
    read -p "Enter something: " val1
    echo First Name: $val1
    read -p "Enter something: " val2
    echo Last Name: $val2
    echo $val1 $val2 invoked $1
    echo  $1 "completed successfully"

    Hello World
    Enter something: albin
    First Name: albin
    Enter something: suresh
    Last Name: suresh
    albin suresh invoked install
    install completed successfully

    Hello World
    First Name: albin
    Last Name: suresh
    albin suresh invoked install
    install completed successfully

为什么会发生这种情况？这些“输入内容：”消息将转到哪个流？？？

我尝试在谷歌上搜索bash

read

命令并获得以下链接：

-p提示符：在尝试读取任何输入之前，显示提示符，不带尾随换行符仅当输入来自终端时，才会显示提示。

显然，如果输入来自非终端，如示例中所示，则不会显示提示
