我试图将存储在变量中的字符串与三个不同的字符串进行比较，如果它们都不匹配，则抛出错误。我尝试使用逻辑运算符 OR 在单个 if 语句中执行此操作。但是每次我收到错误时，即使存储在变量中的值与可能的值之一相同。请找到我尝试过的片段。

if [[ "$TYPE" != "LOCAL" || "$TYPE" != "REMOTE" || "$TYPE" != "BOTH" ]]; then
    echo -e "\n\tINCORRECT OR NULL ARGUMENTS PASSED. PLEASE VERIFY AND CORRECT THE USAGE MENTIONED AS BELOW: \n"
    Usage
    exit 1
fi


if [[ "$TYPE" != "LOCAL" ]] || [["$TYPE" != "REMOTE" ]] || [["$TYPE" != "BOTH" ]]; then
    echo -e "\n\tINCORRECT OR NULL ARGUMENTS PASSED. PLEASE VERIFY AND CORRECT THE USAGE MENTIONED AS BELOW: \n"
    Usage
    exit 1
fi
