Dir command does not work as I want it to

dir /b command
dir /s command
dir command file size
dos dir command only file names
powershell dir command
dir filename only no extension
dir /p
list all folders in a directory cmd

I am supposed to write a batch file which would find files starting with letter a and end with the extension .dll.

Here is what I came up with:

@echo off
dir /b *.dll C:\windows\system32\ > dll.txt
dir /b a* C:\windows\system32\ > a.txt

My script does not work the way I want because it lists all the files from system32 directory.

Can anyone help me fix it the way it should be?

dir /b *.dll C:\windows\system32\ lists all files that match *.dll, then all files that match C:\windows\system32\ - that is, all files in that folder. The correct syntax for what you want to do is:

dir /b "C:\windows\system32\*.dll"

Same with the other line:

dir /b "C:\windows\system32\a*"

how do I find all exe files using command line for windows?, Can you use the DIR command to show only executables How? The dir command is a Command Prompt command used to display a list of the files and subfolders contained in a folder. For each file or folder listed, the dir command will, by default, show the date and time the item was last changed, if the item is a folder (labeled as <DIR>) or file,

You can try like this batch :

@echo off
Set Log=%~dp0Files_DLL.txt
CD /D %Windir%\system32\
Dir /b a*.dll>>%Log%
Start "" %Log%

MS-DOS and Windows command line dir command, available. By default, it displays the name, size, and last modification time of every file in the current directory. dir command can be used to list the files from command prompt. This article explains the syntax for different usecases. Lists the subfolders/files names in bare format.dir /b This command prints the file names. No other file meta data like file modified time, file size etc are not displayed.

The command DIR supports multiple arguments for directory listings.

dir /b *.dll C:\windows\system32\ > dll.txt

This command line results in writing to file dll.txt

  1. all non-hidden file and folder names matching in current directory the wildcard pattern *.dll and
  2. all non-hidden file and folder names matching in directory C:\windows\system32\ the default wildcard pattern *.

The next command line is:

dir /b a* C:\windows\system32\ > a.txt

This command line results in writing to file a.txt

  1. all non-hidden file and folder names matching in current directory the wildcard pattern a* and
  2. all non-hidden file and folder names matching in directory C:\windows\system32\ the default wildcard pattern *.

But most likely wanted is writing to dll.txt all *.dll files in directory C:\windows\system32\ and to a.txt all a* files in directory C:\windows\system32\ with both times including also matching files with hidden attribute set. For that reason the command lines to use is:

dir %SystemRoot%\System32\*.dll /A-D /B >dll.txt
dir %SystemRoot%\System32\a* /A-D /B >a.txt

The option /A-D disables listing of directories (attribute not directory) matching by chance also the wildcard patterns and enabling listing of hidden files too.

For help on command DIR run in a command prompt window dir /?.

By the way: Windows file system redirector should be taken into account. The two command lines output to the text files the *.dll and a* files in directory %SystemRoot%\SysWOW64 if the batch file is executed by 32-bit cmd.exe in %SystemRoot%\SysWOW64\ on 64-bit Windows because of batch file is started from within a 32-bit application.

The batch file below can be used to make sure getting the listings for Windows system directory according to Windows architecture which makes a difference on 64-bit Windows.

set "SystemFolder=%SystemRoot%\System32"
if exist "%SystemRoot%\Sysnative\cmd.exe" set "SystemFolder=%SystemRoot%\Sysnative"
dir %SystemFolder%\*.dll /A-D /B >dll.txt
dir %SystemFolder%\a* /A-D /B >a.txt

The very special %SystemRoot%\Sysnative redirector does not exist for 64-bit applications and so also not for batch files executed by 64-bit cmd.exe in directory %SystemRoot%\System32\. Please note that Sysnative is whether a directory nor a symbolic link. It is only possible to check if a file exists in %SystemRoot%\Sysnative, but not if %SystemRoot%\Sysnative itself exists.

  • I cannot believe your code lists all files. Anyway, have you ever considered the pattern a*.dll?
  • As I have written below, I expressed myself wrong. One list should contain .dll files from system32 folder and another list should contain only files from the same directory but starting with letter a.
  • I made a mistake in expressing myself. "a.txt" is supposed to contain only file names starting with letter a, and "dll.txt" is supposed to contain only files with .dll extension. I've just fixed it halfway to make at least .dll list work properly by adding find command. Now it looks like this 'dir /b *.dll C:\windows\system32\ | find ".dll" > dll.txt'.
