sshpass 不会运行在获取脚本时在 Ubuntu 远程主机上提供命令，但会在 windows 上运行并且在同一脚本中运行

Question

我在这里搜索了一下，找不到遇到此问题的人。

我有一个 tool/script 我正在构建，它使用 sshpass 登录到远程主机并提取日志、重新启动等...如果我运行主脚本中的函数它运行没有问题。如果我使用函数获取脚本，那么如果它访问 windows IOT Core 远程主机，它运行很好，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

航站楼

这是有效的：

mainFile.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

我更喜欢但不起作用的：

MainFile.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：

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

对于任何关心安全的人，我没有在脚本中硬编码任何密码。我只是为了这个问题这样写的。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 OS 会有所不同，但这是唯一不同的地方。我尝试了运行ning 只是一个 ls 或 echo 而没有。我也尝试了 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所见，已加载 linux 系统信息。这在第二个输出中没有发生。

我知道我可以将所有内容都放在一个脚本中，但我希望扩展此工具，并且宁愿在工具准备就绪时只添加一个菜单项。保持环境清洁也能让我很容易把它传给其他人扩展。

我希望我为一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。

提前致谢。

想通了。我觉得我应该知道这一点，但不知怎的，它让我忘记了。我必须在 sshpass 上添加 -t -oStrictHostKeyChecking=no。所以命令应该是

sshpass -p 'password' ssh -t -oStrictHostKeyChecking=no "user@0.0.0.0" <<EOF
echo 'password' | sudo -S docker logs --tail 10 container
EOF

希望有人能找到它并对他们有所帮助。

sshpass 不会 运行 在获取脚本时在 Ubuntu 远程主机上提供命令，但会在 windows 上 运行 并且在同一脚本中 运行

sshpass will not run provided command on Ubuntu remote host when script is sourced, but does run on windows and if run within the same script

linux

bash

function

powershell
