批处理文件:检查是否存在带有模式的文件

Question

我有一个奇怪的情况,我不知道有什么问题

我需要检查目录中是否存在至少一个带模式的文件.

IF EXIST d:\*Backup*.* (
   ECHO "file exist"
) ELSE (
   ECHO "file not exist"
)

如果在d:\我有一个文件x_Backup.txt和一个文件夹Backup我得到file exist但是如果我只有文件夹Backup我再次得到file exist,似乎路径中的点被忽略.

还有一些未记录的通配符,您也可以使用它们来实现此目的.

IF EXIST "D:\*Backup*.<" (
   ECHO "file exist"
) ELSE (
   ECHO "file not exist"
)

在以下两个链接中详细讨论了这个通配符选项和其他选项. http://www.dostips.com/forum/viewtopic.php?t=6207

从这些链接:

The following wildcard characters can be used in the pattern string.

用这个; 它适用于任何特定模式:

set "fileExist="
for %%a in (d:\*Backup*.*) do set "fileExist=1" & goto continue
:continue
IF DEFINED fileExist (
   ECHO "file exist"
) ELSE (
   ECHO "file not exist"
)

这是另一种选择。

dir d:\*back*.* /b /a-d >nul 2>&1
if errorlevel 1 echo files exist
