Batch-File和else命令来保存文件

Question

我尝试过这个命令，但它不起作用：

...
echo NOTE: if you don't have an account leave it blank
echo Enter the username please
set /p USERNM=Type : 
if USERNM=" " (
echo Added 1000 coins to your account
) >Folder\logs.txt
if else (
echo Added 1000 coins to the account %USERNM% 
) >Folder\logs.txt
...

让我解释一下，批处理文件将请求用户名将其保存在一个logs.txt文件中。如果用户没有帐户，他会将其保留为空白，并显示上面的消息，如果他有一个帐户，他将输入该帐户，日志文件将包含他的用户名，问题是代码不工作。如果有人知道解决方案，请告诉我，谢谢！

试试这个：

...
echo;NOTE: if you don't have an account leave it blank
echo;Enter the username please
set /p "USERNM=Type : "
if not defined "USERNM" (
    echo;Added 1000 coins to your account > "Folder\logs.txt"
) else (
    echo;Added 1000 coins to the account %USERNM% > "Folder\logs.txt"
)
