使用 {} 执行多个命令时出现 bash 脚本错误

Question

我正在编写一个 bash 脚本（如下）并使用

sudo bash ./script.bash 

结果错误：

line 22: syntax error near unexpected token `fi'

剧本：

getent passwd myuser > /dev/null
if [ $? -eq 0 ]; then
    echo "info: user myuser already exists"
else
    sudo useradd -M myuser > /dev/null || { echo "ERROR: could not create user myuser."; exit 1 }
    echo "info: user myuser created successfully"
fi

如果我删除该行：

|| { echo "ERROR: could not create user fiminion"; exit 1 }

一切似乎都有效..我不明白我错过了什么..：/
