Bash 腳本未如預期運行

我試圖獲取下面的腳本來獲取傳遞給它的連接 uuid（由網路管理器），將其與我的家庭連接（物理和 VPN）的 uuid 列表進行比較，並運行某些命令。然而，即使 uuid 是正確的，腳本似乎總是轉到“else”子句。

#!/bin/bash

echo $CONNECTION_UUID

Home_UUIDs="5b509e73-8f08-475c-a14d-7037f2f4b87a ba36c69e-c3f1-4480-a484-1eea105311b2 f3889052-719f-4b88-8b94-e1fa189d44f9"

if [[ "$Home_UUIDs" == *"$CONNECTION_UUID"* ]]; then
        case "$2" in
                up)
                echo "Conecting to Home netork..."
                ntpdate -vs 192.168.0.18
                service ntp start
                ;;
                down)
                echo "Disconnecting from home network"
                service ntp stop
                ;;
        esac
else
        echo "We're not at home..."
        service ntp stop
fi

exit 0

它似乎對我來說適用於所有三個 uuid：

#!/bin/bash
Home_UUIDs='5b509e73-8f08-475c-a14d-7037f2f4b87a ba36c69e-c3f1-4480-a484-1eea105311b2 f3889052-719f-4b88-8b94-e1fa189d44f9'

for CONNECTION_UUID in 5b509e73-8f08-475c-a14d-7037f2f4b87a \
                       ba36c69e-c3f1-4480-a484-1eea105311b2 \
                       f3889052-719f-4b88-8b94-e1fa189d44f9 ; do

    if [[ "$Home_UUIDs" == *"$CONNECTION_UUID"* ]]; then
        echo "We're at home!"
    else
        echo "We're not at home..."
    fi
done

$CONNECTION_UUID 中還有其他字元嗎？

最後透過將括號中的語句替換為來修復它

[[ "$Home_UUIDs" =~ "$CONNECTION_UUID" ]]

代替

[[ "$Home_UUIDs" == *"$CONNECTION_UUID"* ]]
