Recursive Unzipping with 7z.exe - windows

I stumbled across the below line as a means of extracting every .zip file in every subfolder.
FOR /F "usebackq" %a in (`DIR /s /b *.zip`) do 7z.exe e %a
I've tried this on a WinXP cmd.exe prompt and I get the error:
"a was unexpected at this time."
Can somebody please tell me whats wrong with the above line. Is this a 7z.exe error or is there something wrong with the batch script syntax. I did cut and paste this into a .bat file.
Cheers

Try to change %a with %%a:
FOR /F "usebackq" %%a in (`DIR /s /b *.zip`) do 7z.exe e %%a

Building on #PA.'s answer (remember to remove the #echo when you've verified that the output is what you want), if you want to preserve the directory structure inside the zip file, use the x command instead of e:
FOR /R %a IN (*.zip) DO #echo 7z x "%a"
And if you want to extract the files into a folder with the same name as their respective zip file, use the -o switch and the %~n filename extractor prefix:
FOR /R %a IN (*.zip) DO #echo 7z x "%a" -o"%~na"
Finally, if you want to do all of the above and overwrite any existing files, use the -aoa switch:
FOR /R %a IN (*.zip) DO #echo 7z x "%a" -o"%~na" -aoa

Batch file
Here it is, all condensed. The following is a batch script that will work for all zip files in the current folder (assuming 7zip is installed). It defaults to echoing what commands would run and only runs when you pass in /y (as in, yes, please do the unzipping now).
:: To actually include the path expansion character (tilde), I had to give valid numbers; see http://ss64.com/nt/rem.html for bug reference. Also, try call /? for more info.
#REM The %~n0 extracts the name sans extension to use as output folder. If you need full paths, use "%~dpn0". The -y forces overwriting by saying yes to everything. Or use -aoa to overwrite.
#REM Using `x` instead of `e` maintains dir structure (usually what we want)
#FOR /R %%a IN (*.zip) DO #(
#if [%1] EQU [/y] (
#7z x "%%a" -o"%%~dpna" -aoa
) else (
#echo 7z x "%%a" -o"%%~dpna" -aoa
)
)
#echo USAGE: Use /y to actually do the extraction

read HELP FOR and then try the following in a command prompt...
FOR /R %a IN (*.zip) DO #ECHO 7z e "%a"
note that we have enclosed %a in "
Once you have checked the validity of the output, remove the ECHO. I would suggest to move the command into a BAT file. In that case, change %a to %%a
#echo off
FOR /R %%a IN (*.zip) DO (
7z e "%%a"
)

Windows batch - match folders with a dot (.) in the folder name

I'm trying to figure out how to match folders with a dot in the file name (e.g., ".svn") in a Windows batch script.
Here's the basic script:
setlocal
pushd c:\myDir
#echo off
FOR /D /r %%G in ("*\.whatever") DO (
echo %%G
REM do stuff
)
#echo on
popd
endlocal
This works just fine for most folder names (e.g., "*bin"), but I can't figure out the method to specify a folder with the dot. "*.whatever" and "*\.whatever" return no results. I'm guessing I'm missing some escape character or something equally simple, but I haven't been able to find any documentation on it.
(Before anyone asks, no I'm not trying to recursively delete subversion folders; "*.svn" is just an example.)
Maybe I am missing something, but as you say it seems simple
for /r /d %%a in (.*) do echo %%~fa
But if the folders are hidden, the normal for will not be able to see them, so we need to execute a dir command an process its output with a for /f
for /f "delims=" %%a in ('dir /ad /s /b .*') do echo %%~fa

Win cmd rar each file separately while keeping the name, with spaces

I'm using Windows and I have a huge list of files
something nextthing.ext
other something.ext
banana apple.ext
I'm trying to generate the following:
something nextthing.rar
other something.rar
banana apple.rar
I've done some research and I couldn't find how to do this. I know WinRAR has a built in way to do this, but it won't let me keep the names. It just renames them to Foldername1.rar, Foldername2.rar ....
I tried using the following command line:
for /f "delims=|" %f in ('dir /b "C:\Users\Adam\
Desktop\Files"') do rar a %f *.rar
However, it doesn't generate all files and they seem to be named wrongly...
For example, what should be banana apple.rar becomes banana.rar and apple.rar
Okay, found how....
#echo off &setlocal
set "path=C:\Program Files\WinRAR;%path%"
:indiv
echo(
echo(
FOR %%i IN (*) do (
rar a "%%~ni.rar" "%%~i" || echo Error building archive!
)
You can use in a command prompt window to compress each file in a directory into a separate archive:
for /f "delims=" %f in ('dir "%USERPROFILE%\Desktop\Files" /B /A-D') do "%ProgramFiles%\WinRAR\Rar.exe" a -ep1 -idcdp "%~nf.rar" "%f"
Important are the double quotes around %f as some file names contain 1 or more spaces and in this case the file names must be enclosed in double quotes.
Above command for usage in a batch file:
#echo off
for /f "delims=" %%f in ('dir "%USERPROFILE%\Desktop\Files" /B /A-D') do "%ProgramFiles%\WinRAR\Rar.exe" a -ep1 -idcdp "%%~nf.rar" "%%f"
This command ignores subfolders because of /A-D. It compresses only each file in directory Files on desktop of current user.

Windows batch command: multiple folders

Following Windows batch command converts all tif images in the folder C:\RootFolder\Folder1.
for %%i in (C:\RootFolder\Folder1\*.tif) do "Tiff2Pdf.exe" -o C:\RootFolder\Folder1\%%~ni.pdf %%i
How can I do it for all the folders available in RootFolder?
RootFolder
-Folder1
-Folder2
-Folder3
.
.
Thanks for your time
There's another way - just to add it:
#echo off
for /r "c:\rootfolder\folder1" %%a in (*.tif) do "Tiff2Pdf.exe" -o "%%~dpna.pdf" "%%a"
I also changed the loop variable to a because i is close to l and I and 1 in many fonts.
FOR /F "delims=" %%i IN ('dir /b /s C:\RootFolder\Folder1\*.tif') DO "Tiff2Pdf.exe" -o "%%~dpi%%~ni.pdf" "%%i"
Use dir /s /b to do a full recursive enumeration
Use FOR /F "delims=" to parse the results and handle paths with spaces.
Use the %%~dpi%% to get the directory of each file.
Use %%~ni to get the file's name with out an extension.

Get filename in batch for loop

I have the following For loop in a batch file:
for /R c:\test\src %%i IN (*.*) DO (
MOVE %%i C:\test\destination
ECHO %%i
exit
)
The result of the ECHO outputs the entire file path Ex: C:\Foldername\Filename
I need to ECHO out only the Filename.Is there a specific command which would give me the filename ?
Thanks !
When Command Extensions are enabled (Windows XP and newer, roughly), you can use the syntax %~nF (where F is the variable and ~n is the request for its name) to only get the filename.
FOR /R C:\Directory %F in (*.*) do echo %~nF
should echo only the filenames.
or Just %~F will give you the full path and full file name.
For example, if you want to register all *.ax files in the current directory....
FOR /R C:. %F in (*.ax) do regsvr32 "%~F"
This works quite nicely in Win7 (64bit) :-)
The answer by #AKX works on the command line, but not within a batch file. Within a batch file, you need an extra %, like this:
#echo off
for /R TutorialSteps %%F in (*.py) do echo %%~nF
I am a little late but I used this:
dir /B *.* > dir_file.txt
then you can make a simple FOR loop to extract the file name and use them. e.g:
for /f "tokens=* delims= " %%a in (dir_file.txt) do (
gawk -f awk_script_file.awk %%a
)
or store them into Vars (!N1!, !N2!..!Nn!) for later use. e.g:
set /a N=0
for /f "tokens=* delims= " %%a in (dir_file.txt) do (
set /a N+=1
set v[!N!]=%%a
)
If you want to remain both filename (only) and extension, you may use %~nxF:
FOR /R C:\Directory %F in (*.*) do echo %~nxF

Iterate all files in a directory using a 'for' loop

How can I iterate over each file in a directory using a for loop?
And how could I tell if a certain entry is a directory or if it's just a file?
This lists all the files (and only the files) in the current directory and its subdirectories recursively:
for /r %i in (*) do echo %i
Also if you run that command in a batch file you need to double the % signs.
for /r %%i in (*) do echo %%i
(thanks #agnul)
Iterate through...
...files in current dir: for %f in (.\*) do #echo %f
...subdirs in current dir: for /D %s in (.\*) do #echo %s
...files in current and all subdirs: for /R %f in (.\*) do #echo %f
...subdirs in current and all subdirs: for /R /D %s in (.\*) do #echo %s
Unfortunately I did not find any way to iterate over files and subdirs at the same time.
Just use cygwin with its bash for much more functionality.
Apart from this: Did you notice, that the buildin help of MS Windows is a great resource for descriptions of cmd's command line syntax?
Also have a look here: http://technet.microsoft.com/en-us/library/bb490890.aspx
To iterate over each file a for loop will work:
for %%f in (directory\path\*) do ( something_here )
In my case I also wanted the file content, name, etc.
This lead to a few issues and I thought my use case might help. Here is a loop that reads info from each '.txt' file in a directory and allows you do do something with it (setx for instance).
#ECHO OFF
setlocal enabledelayedexpansion
for %%f in (directory\path\*.txt) do (
set /p val=<%%f
echo "fullname: %%f"
echo "name: %%~nf"
echo "contents: !val!"
)
*Limitation: val<=%%f will only get the first line of the file.
There is a subtle difference between running FOR from the command line and from a batch file. In a batch file, you need to put two % characters in front of each variable reference.
From a command line:
FOR %i IN (*) DO ECHO %i
From a batch file:
FOR %%i IN (*) DO ECHO %%i
This for-loop will list all files in a directory.
pushd somedir
for /f "delims=" %%f in ('dir /b /a-d-h-s') do echo %%f
popd
"delims=" is useful to show long filenames with spaces in it....
'/b" show only names, not size dates etc..
Some things to know about dir's /a argument.
Any use of "/a" would list everything, including hidden and system attributes.
"/ad" would only show subdirectories, including hidden and system ones.
"/a-d" argument eliminates content with 'D'irectory attribute.
"/a-d-h-s" will show everything, but entries with 'D'irectory, 'H'idden 'S'ystem attribute.
If you use this on the commandline, remove a "%".
Hope this helps.
%1 refers to the first argument passed in and can't be used in an iterator.
Try this:
#echo off
for %%i in (*.*) do echo %%i
I had trouble getting jop's answer to work with an absolute path until I found this reference: https://ss64.com/nt/for_r.html
The following example loops through all files in a directory given by the absolute path.
For /R C:\absoulte\path\ %%G IN (*.*) do (
Echo %%G
)
Here's my go with comments in the code.
I'm just brushing up by biatch skills so forgive any blatant errors.
I tried to write an all in one solution as best I can with a little modification where the user requires it.
Some important notes: Just change the variable recursive to FALSE if you only want the root directories files and folders processed. Otherwise, it goes through all folders and files.
C&C most welcome...

To iterate through all files and folders you can use
for /F "delims=" %%a in ('dir /b /s') do echo %%a
To iterate through all folders only not with files, then you can use
for /F "delims=" %%a in ('dir /a:d /b /s') do echo %%a
Where /s will give all results throughout the directory tree in unlimited depth. You can skip /s if you want to iterate through the content of that folder not their sub folder
Implementing search in iteration
To iterate through a particular named files and folders you can search for the name and iterate using for loop
for /F "delims=" %%a in ('dir "file or folder name" /b /s') do echo %%a
To iterate through a particular named folders/directories and not files, then use /AD in the same command
for /F "delims=" %%a in ('dir "folder name" /b /AD /s') do echo %%a
for %1 in (*.*) do echo %1
Try "HELP FOR" in cmd for a full guide
This is the guide for XP commands. http://www.ss64.com/nt/
The following code creates a file Named "AllFilesInCurrentDirectorylist.txt" in the current Directory, which contains the list of all files (Only Files) in the current Directory. Check it out
dir /b /a-d > AllFilesInCurrentDirectorylist.txt
It could also use the forfiles command:
forfiles /s
and also check if it is a directory
forfiles /p c:\ /s /m *.* /c "cmd /c if #isdir==true echo #file is a directory"
I would use vbscript (Windows Scripting Host), because in batch I'm sure you cannot tell that a name is a file or a directory.
In vbs, it can be something like this:
Dim fileSystemObject
Set fileSystemObject = CreateObject("Scripting.FileSystemObject")
Dim mainFolder
Set mainFolder = fileSystemObject.GetFolder(myFolder)
Dim files
Set files = mainFolder.Files
For Each file in files
...
Next
Dim subFolders
Set subFolders = mainFolder.SubFolders
For Each folder in subFolders
...
Next
Check FileSystemObject on MSDN.
I use the xcopy command with the /L option to get the file names. So if you want to get either a directory or all the files in the subdirectory you could do something like this:
for /f "delims=" %%a IN ('xcopy "D:\*.pdf" c:\ /l') do echo %%a
I just use the c:\ as the destination because it always exists on windows systems and it is not copying so it does not matter. if you want the subdirectories too just use /s option on the end. You can also use the other switches of xcopy if you need them for other reasons.
Try this to test if a file is a directory:
FOR /F "delims=" %I IN ('DIR /B /AD "filename" 2^>^&1 ^>NUL') DO IF "%I" == "File Not Found" ECHO Not a directory
This only will tell you whether a file is NOT a directory, which will also be true if the file doesn't exist, so be sure to check for that first if you need to. The carets (^) are used to escape the redirect symbols and the file listing output is redirected to NUL to prevent it from being displayed, while the DIR listing's error output is redirected to the output so you can test against DIR's message "File Not Found".
try this:
::Example directory
set SetupDir=C:\Users
::Loop in the folder with "/r" to search in recursive folders, %%f being a loop ::variable
for /r "%SetupDir%" %%f in (*.msi *.exe) do set /a counter+=1
echo there are %counter% files in your folder
it counts .msi and .exe files in your directory (and in the sub directory). So it also makes the difference between folders and files as executables.
Just add an extension (.pptx .docx ..) if you need to filter other files in the loop
In my case I had to delete all the files and folders underneath a temp folder. So this is how I ended up doing it. I had to run two loops one for file and one for folders. If files or folders have spaces in their names then you have to use " "
cd %USERPROFILE%\AppData\Local\Temp\
rem files only
for /r %%a in (*) do (
echo deleting file "%%a" ...
if exist "%%a" del /s /q "%%a"
)
rem folders only
for /D %%a in (*) do (
echo deleting folder "%%a" ...
if exist "%%a" rmdir /s /q "%%a"
)
