linux - 获取脚本时，sshpass 不会在 Ubuntu 远程主机上运行提供的命令，但会在 Windows 上运行并且如果在同一脚本中运行

问题描述

我在这里搜索了一下，找不到遇到这个问题的人。

我有一个我正在构建的工具/脚本，它使用 sshpass 登录到远程主机并提取日志、重新启动等......如果我在主脚本中运行该函数，它运行没有问题。如果我使用该函数获取脚本，那么如果它访问 Windows IOT Core 远程主机，它运行良好，但如果远程主机是 linux，则不会执行命令。

我的设备：
Macbook Pro 2018
macOs Mojave 10.14.2

应用
终端

这是有效的：

主文件.sh：

#!/bin/bash

function pullWindowsLog {
    sshpass -p 'password' ssh user@0.0.0.0 <<EOF
powershell.exe
Get-Content  c:\Path\To\Log\Log.log -tail 10
EOF
}

function pullLinuxLog {
    sshpass -p 'password' ssh user@0.0.0.0 <<EOF
echo 'password' | sudo -S docker logs --tail 10 container
EOF
}



function mainMenu {
    local PS3="What would you like to do?"
    local options=("Pull Windows Log" "Pull Linux Logs" "Quit")
    select opt in "${options[@]}"
    do
        case $opt in
            "Pull Windows Log")
                pullWindowsLog
                ;;
            "Pull Linux Logs")
                pullLinuxLog
                ;;
            "Quit")
                clear
                break
                ;;
            *) echo "\ninvalid option \n";;
        esac
    done
}

mainMenu

输出：

1) Pull Windows Log
2) Pull Linux Logs
3) Quit

我更喜欢，但不工作：

主文件.sh：

#!/bin/bash

source pullWindowsLog.sh
source pullLinuxLog.sh

function mainMenu {
    local PS3="What would you like to do?"
    local options=("Pull Windows Log" "Pull Linux Logs" "Quit")
    select opt in "${options[@]}"
    do
        case $opt in
            "Pull Windows Log")
                pullWindowsLog
                ;;
            "Pull Linux Logs")
                pullLinuxLog
                ;;
            "Quit")
                clear
                break
                ;;
            *) echo "\ninvalid option \n";;
        esac
    done
}

mainMenu

pullWindowsLog.sh：

#!/bin/bash

function pullWindowsLog {
    sshpass -p 'password' ssh user@0.0.0.0 <<EOF
powershell.exe
Get-Content  c:\Path\To\Log\Log.log -tail 10
EOF
}

pullLinuxLog.sh：

#!/bin/bash

function pullLinuxLog {
    sshpass -p 'password' ssh user@0.0.0.0 <<EOF
echo 'password' | sudo -S docker logs --tail 10 container
EOF
}

输出：

对于任何关心安全的人，我没有在脚本中硬编码任何密码。我只是为这个问题这样写的。我没有传递变量的问题，只是 sshpass 在获取时的行为方式。我不明白为什么远程主机操作系统会有所不同，但这是唯一不同的地方。我试着只运行一个ls或echo什么都没有。我也尝试过sshpass -p 'password' ssh user@0.0.0.0 <command>，甚至没有得到Pseudo-terminal will not be allocated because stdin is not a terminal.。正如您在第一个输出中看到的那样，加载了 linux 系统信息。这在第二个输出中没有发生。

我知道我可以在一个脚本中包含所有内容，但我希望扩展这个工具，并且宁愿在工具准备好时添加一个菜单项。保持环境清洁也可以让我轻松地将其传递给其他人以进行扩展。

我希望我为某些终端天才提供了足够的信息（此时可能是 TMI）来解决这个问题。

先感谢您。
