Command line 我需要在一行中获得文件夹列表

我有一句话（我知道很简单）：

结果是：

AAA
BBB
CCC
DDD

（应该如此） 但是我需要这个输出：

**AAA | BBB | CCC | DDD**

有人能帮忙做这件事吗？但是，以下批处理文件也会有所帮助：

@ECHO OFF
SETLOCAL EnableExtensions DisableDelayedExpansion

echo --- Original:
FOR /f "delims=" %%G in (List.txt) DO ECHO %%G

echo --- One line:
FOR /f "delims=" %%G in (List.txt) DO <NUL set /P "=%%G|"
echo(

echo --- Another one line:
set "_FirstLine="
FOR /f "delims=" %%G in (List.txt) DO ( 
  if defined _FirstLine (
    <NUL set /P "=|%%G"
  ) else (
    <NUL set /P "=%%G"
    set "_FirstLine=done"
  )
)
echo(

请注意，

echo（

命令将一个空行打印到控制台（此处重要的是在

for

循环结束后退出同一行的打印）

@ECHO OFF
SETLOCAL EnableExtensions DisableDelayedExpansion

echo --- Original:
FOR /f "delims=" %%G in (List.txt) DO ECHO %%G

echo --- One line:
FOR /f "delims=" %%G in (List.txt) DO <NUL set /P "=%%G|"
echo(

echo --- Another one line:
set "_FirstLine="
FOR /f "delims=" %%G in (List.txt) DO ( 
  if defined _FirstLine (
    <NUL set /P "=|%%G"
  ) else (
    <NUL set /P "=%%G"
    set "_FirstLine=done"
  )
)
echo(

--- Original:
AAA
BBB
CCC
DDD
--- One line:
AAA|BBB|CCC|DDD|
--- Another one line:
AAA|BBB|CCC|DDD
