有谁知道"未预期的记号 "else" 附近有语法错误"怎么解决吗?

Question

编写了一个shell文件用于在linux上利用wine启动游戏.
我用的系统是manjaro linux.
在我运行时出现错误

./test.sh: 行 25: 未预期的记号 "else" 附近有语法错误
./test.sh: 行 25: `else'

在网上找了半天都没解决办法
文件如下

```bash
#!/bin/bash

if mount | grep "/dev/nvme0n1p3";then
echo "Which Hoyo do you want to open?    [GenshinImpact/g or StarRail/r]"
read gname

if test -z "$(mount | grep "/dev/nvme0n1p3")";then
    PATH=`mount | grep /dev/nvme0n1p3 | awk -F " " '{print $3}'`
    if [$PATH = /home/cz/ntfs];then
        if [$gname = r];then
            mangohud wine /home/cz/work/patch/jadeite.exe "/home/cz/ntfs/Program Files/miHoYo Launcher/games/Star Rail Game/StarRail.exe"
        elif [$gname = g];then
            mangohud wine "/home/cz/ntfs/Program Files/HoYoPlay/games/Genshin Impact game/GenshinImpact.exe"
        fi
    else
        sudo unmount $PATH
        sudo ntfs-3g /dev/nvme0n1p3 /home/cz/ntfs
        if [$gname = r];then
            mangohud wine /home/cz/work/patch/jadeite.exe "/home/cz/ntfs/Program Files/miHoYo Launcher/games/Star Rail Game/StarRail.exe"
        elif [$gname = g];then
            mangohud wine "/home/cz/ntfs/Program Files/HoYoPlay/games/Genshin Impact game/GenshinImpact.exe"
        else
            echo "Are you sure?"
        fi
else
    sudo ntfs-3g /dev/nvme0n1p3 /home/cz/ntfs
    if [$gname = r];then
        mangohud wine /home/cz/work/patch/jadeite.exe "/home/cz/ntfs/Program Files/miHoYo Launcher/games/Star Rail Game/StarRail.exe"

你遇到的错误“未预期的记号 'else' 附近有语法错误”通常是由于条件语句的格式不正确造成的。在 Bash 中，[ 和 ] 之间需要有空格。请检查以下几点：

1. 条件语句的格式：确保 if 条件语句的格式正确，应该在 [ 和 ] 之间添加空格。
2. 分支结构的嵌套：确保每个 if 都有对应的 fi。

你可以修改你的代码如下：

#!/bin/bash

if mount | grep "/dev/nvme0n1p3"; then
    echo "Which Hoyo do you want to open?    [GenshinImpact/g or StarRail/r]"
    read gname

    if test -z "$(mount | grep "/dev/nvme0n1p3")"; then
        PATH=$(mount | grep /dev/nvme0n1p3 | awk -F " " '{print $3}')
        if [ "$PATH" = "/home/cz/ntfs" ]; then
            if [ "$gname" = "r" ]; then
                mangohud wine /home/cz/work/patch/jadeite.exe "/home/cz/ntfs/Program Files/miHoYo Launcher/games/Star Rail Game/StarRail.exe"
            elif [ "$gname" = "g" ]; then
                mangohud wine "/home/cz/ntfs/Program Files/HoYoPlay/games/Genshin Impact game/GenshinImpact.exe"
            fi
        else
            sudo umount "$PATH"
            sudo ntfs-3g /dev/nvme0n1p3 /home/cz/ntfs
            if [ "$gname" = "r" ]; then
                mangohud wine /home/cz/work/patch/jadeite.exe "/home/cz/ntfs/Program Files/miHoYo Launcher/games/Star Rail Game/StarRail.exe"
            elif [ "$gname" = "g" ]; then
                mangohud wine "/home/cz/ntfs/Program Files/HoYoPlay/games/Genshin Impact game/GenshinImpact.exe"
            else
                echo "Are you sure?"
            fi
        fi
    else
        sudo ntfs-3g /dev/nvme0n1p3 /home/cz/ntfs
        if [ "$gname" = "r" ]; then
            mangohud wine /home/cz/work/patch/jadeite.exe "/home/cz/ntfs/Program Files/miHoYo Launcher/games/Star Rail Game/StarRail.exe"
        elif [ "$gname" = "g" ]; then
            mangohud wine "/home/cz/ntfs/Program Files/HoYoPlay/games/Genshin Impact game/GenshinImpact.exe"
        else
            echo "Are you sure?"
        fi
    fi
fi

修改要点：

• 在所有的 [ 和 ] 之间添加了空格。
• 使用 "$变量名" 来引用变量，以避免潜在的空格问题。

请试试这个修改后的代码，看看能否解决你的问题！
