Batch file echo之后，为什么cmd不能打开到所需的位置？

在此代码中，cmd未打开到所需位置：

::fileinfo: "javaday.bat" by Wolfpack08 4/2014
@echo off
::"Good morning" appears in CMD.
echo "Good morning."

::Important directories are opened.
%SystemRoot%\explorer.exe "c:\Users\Wolfpack08\java_apps"
%SystemRoot%\explorer.exe "c:\utils"

::Open up the programs I use.
"C:\Program Files (x86)\Notepad++\notepad++.exe"
"C:\Program Files (x86)\Anki\anki.exe"

::Open up cmd prompt to the desired location.
::THIS IS THE PROBLEMATIC LINE.
cmd /k start "" /d"c:\Users\wolfpack08\java_apps"

::fileinfo: "javaday.bat" by Wolfpack08 4/2014
@echo off

::Open up cmd prompt to the desired location.
::THIS IS THE PROBLEMATIC LINE.
cmd /k start "" /d"c:\Users\wolfpack08\java_apps"

::"Good morning" appears in CMD.
echo "Good morning."

::Important directories are opened.
%SystemRoot%\explorer.exe "c:\Users\Wolfpack08\java_apps"
%SystemRoot%\explorer.exe "c:\utils"

::Open up the programs I use.
"C:\Program Files (x86)\Notepad++\notepad++.exe"
"C:\Program Files (x86)\Anki\anki.exe"

现在，在下面的代码中，cmd确实打开到所需的位置：

::fileinfo: "javaday.bat" by Wolfpack08 4/2014
@echo off
::"Good morning" appears in CMD.
echo "Good morning."

::Important directories are opened.
%SystemRoot%\explorer.exe "c:\Users\Wolfpack08\java_apps"
%SystemRoot%\explorer.exe "c:\utils"

::Open up the programs I use.
"C:\Program Files (x86)\Notepad++\notepad++.exe"
"C:\Program Files (x86)\Anki\anki.exe"

::Open up cmd prompt to the desired location.
::THIS IS THE PROBLEMATIC LINE.
cmd /k start "" /d"c:\Users\wolfpack08\java_apps"

::fileinfo: "javaday.bat" by Wolfpack08 4/2014
@echo off

::Open up cmd prompt to the desired location.
::THIS IS THE PROBLEMATIC LINE.
cmd /k start "" /d"c:\Users\wolfpack08\java_apps"

::"Good morning" appears in CMD.
echo "Good morning."

::Important directories are opened.
%SystemRoot%\explorer.exe "c:\Users\Wolfpack08\java_apps"
%SystemRoot%\explorer.exe "c:\utils"

::Open up the programs I use.
"C:\Program Files (x86)\Notepad++\notepad++.exe"
"C:\Program Files (x86)\Anki\anki.exe"

预期行为 当我运行javaday.bat时，我希望cmd的一个实例能够向c:\Users\wolfpack08\java\u应用程序打开

实际行为 “早上好”仍保留在cmd中。没有光标（我不能打字）

我试过的 试着弄乱代码和注释行

附加信息

---

当cmd已经打开时，它会成功。例如，第二次执行成功。因此，这是一种间歇性问题。

开关执行命令，然后退出。尝试/k开关，它执行命令并保持打开状态。比如：

start cmd /k "cd c:\users\wolfpack08\java_apps"

---

这将在文件夹中打开cmd提示符：

@echo off
start "" /d"c:\Users" cmd /k 

---

这纯粹是猜测，但试着做

echo“早安！”

@merlin2011我已经在做了。问题仍然存在。如果你把“早安！”（不加引号）放在屏幕上，而你只看到“早安”（不加引号），那么你就必须避开这个问题！带^^的字符！或者像merlin2011建议的那样，在引号中加上“早上好！”。我没有注意到这一点，因为我认为除了打开cmd实例之外，echo之后的所有行都已经执行了。如果执行在那里停止，试着移除整个回音线一段时间，看看其他一切是否正常工作。不工作。引号和转义字符不能解决实际问题。
