Bash脚本-带有if / then的While条件[重复]

Question

所以我在理解如何循环条件时遇到了问题。这是我的例子：

#!/bin/bash
echo " Which team do you prefer, FSU or UF?"
read -r TEAM
while [ "$TEAM" != "FSU" || "UF" ]; do
        echo "That was not one of your choices. Please choose FSU or UF"
if [ "$TEAM" == "FSU" ]; then
        echo "You chose the better team"
else [ "$TEAM" == "UF" ];
        echo "You did NOT choose the better team"
fi
done

基本上，我正在寻找的是用户输入，如果不满足该条件，它将循环返回，直到满足正确的输入。 我究竟做错了什么？在此示例中，如果我选择 FSU 或 Uf 之外的输入作为：

"./test.sh：第 4 行：[：缺少 `]' ./test.sh: 第 4 行: UF: command not found"

但是，如果我选择 FSU 或 UF，我会得到同样的错误。

固定脚本：

#!/bin/bash
echo " Which team do you prefer, FSU or UF?"
read -r TEAM
while [[ "$TEAM" != "FSU" && "$TEAM" !=  "UF" ]]; do
        echo "That was not one of your choices. Please choose FSU or UF"
        read -r TEAM
done
if [[ "$TEAM" == "FSU" ]]; then
        echo "You chose the better team"
else [[ "$TEAM" == "UF" ]];
        echo "You did NOT choose the better team"
fi

变化：

查看Done位置，用户输入验证通过后需要退出while loop。

在用户输入失败后，您需要询问用户的输入。因此read -r TEAM 在while loop 中。

您的逻辑比较是OR，而不是while loop 中的AND。
