I'm trying to write a small script to find the absolute path of Rscript in a machine running Windows OS. I assume that Rscript must be found under C:\Program Files\R\R-x.x.x directory, where x.x.x represents any version of R. I have written the following script based on several threads (Find file and return full path using a batch file).
#echo off
SETLOCAL ENABLEDELAYEDEXPANSION
for /d %%a in ("C:\Program Files\R\") do (
if "%%~nxa"=="Rscript.exe" (
set p=%%~dpnxa
)
)
Unfortunately, the if condition assigns p to every file and folder in C:\Program Files\R\R-x.x.x. If anyone has any idea of how to find and assign p properly, I would really appreciate it!
Regards,
Juan
EDIT
I'm adding my full script
#echo off
SETLOCAL ENABLEDELAYEDEXPANSION
for /R %%a in ("C:\Program Files\R\R-*") do (
if /i "%%~nxa"=="Rscript.exe" (
set "p=%%~fa"
)
)
if defined p (
echo %p%
) else (
echo File not found
)
%p% runShinyApp.R 1> ShinyApp.log 2>&1
Not sure why you want to do %%~dpnxa when you can just do %%~fa anyway, here are some ways.
#echo off
for %%a in ("C:\Program Files\R\*") do (
if /i "%%~nxa"=="Rscript.exe" (
set "p=%%~fa"
)
)
another method is to use where, without having to do an if statement, simply because you specify the executable in the where search. You can recursively search for the path in an entire drive, or specify a path, here for instance we recursively search in "C:\Program Files".
#echo off
for /f "delims=" %%a in ('where /r "%programfiles%" "rscript.exe"2^>nul') do set "p=%%~fa"
EDIT after your comments, this should work.
#echo off
for /f "delims=" %%a in ('where /r "%programfiles%\R\R-3.6.3\bin\x64" "rscript.exe"2^>nul') do "%%~fa" runShinyApp.R 1> ShinyApp.log
I would however recommend you specify the path to runShinyApp.R in the do line.
My requirement is to write a batch script to find and replace the a string in all of the *-spec.js files in given set of directories. Hence I have written the batch file and running the batch script as below.
<script file name> <search_string> <replace_string> <folder_path_1> <folder_path_2> <folder_path_n>
(I am sure the folder_path_n will not go beyond 7)
e.g C:\CI\Scripts>replace.bat hello world C:\app\e2e C:\sppa\e2e
So my script is as below.
#echo off
setlocal enabledelayedexpansion
set argCount=0
for %%x in (%*) do (
set /A argCount+=1
set "argVec[!argCount!]=%%~x"
)
set search=%1
set replace=%2
echo Search is %search%
echo Replace is %replace%
for /L %%i in (3,1,%argCount%) do (
set path=!argVec[%%i]!
echo path is !path!
for /R !path! %%F in (*spec.js) do (
echo %%F
)
)
Here it prints the 4 arguments correctly even the path is also printed as expected. In the next step it's expected to loop through the given path and gets all of the files that ends with "spec.js".
e.g not working:
for /R !path! %%F in (*spec.js) do (
echo %%F
)
But it prints nothing. Instead if the variable is replaced with hard coded value, it works as expected.
e.g - working:
for /R C:\app\sppa\e2e %%F in (*spec.js) do (
echo %%F
)
Your help is highly appreciated!
The reason it's not working is that the variable content must be known when the loop is parsed means that it only works with variables that can be expanded without delayed expansion. Nevertheless there is an easy solution as a for /r loop is working with the current path (from ss64).
If the [drive:]path are not specified they will default to the current drive:path.
Just change directory to !path! and then go back:
rem Change into !path! and remember directory coming from
pushd !path!
for /R %%F in (*spec.js) do (
echo %%F
)
rem Change back to origin
popd
I also tried similar as suggested by #Andre Kampling as below.
cd !path!
::echo Changed the path to !path!
FOR /R %%F IN (*spec.js) DO (
echo %%F
)
I have files named as RabcdYYMMKKACCOUNT.TXT in the Subfolders of a folder where YYMM is year, month this will change. KK is another identifier, I want all the files to be renamed to MSFKKDNB.ABC, the KK is the identifier in the input file.
Below is the one i tried and the result of it:
FOR /R %%f IN (*account.txt) DO REN "%%f" *dnb.abc
R00531706AUAccount.txt is renamed to R00531706AUAccount.txtdnb.abc
but the output should be MSFAUDNB.abc
This could be done for example with:
#echo off
setlocal EnableExtensions EnableDelayedExpansion
for /R %%I in (???????????account.txt) do (
set "FileName=%%~nI"
set "NewFileName=MSF!FileName:~9,2!DNB.abc"
if not exist "%%~dpI!NewFileName!" (
ren "%%~fI" "!NewFileName!" 2>nul
if not exist "%%~dpI!NewFileName!" echo Failed to rename file: "%%~fI"
) else (
echo Cannot rename file: "%%~fI"
)
)
endlocal
The file name of found account text file is assigned to environment variable FileName.
The new name for the file is created by concatenating the fixed parts MSF and DNB.abc with the 2 characters to keep from file name using string substitution and delayed expansion.
Next it is checked if a file with new name does not already exist. Is this the case the file renaming is done otherwise an error message is output.
After renaming the file it is checked if that was successful. A slightly different error is output if renaming failed for example because of a sharing violation.
For understanding the used commands and how they work, open a command prompt window, execute there the following commands, and read entirely all help pages displayed for each command very carefully.
echo /?
endlocal /?
for /?
if /?
ren /?
set /?
setlocal /?
Read also the Microsoft article about Using Command Redirection Operators.
Try this:
#Echo Off
For %%A In ("*account.txt") Do (Set "_=%%~nA"
SetLocal EnableDelayedExpansion
Ren "%%A" "MSF!_:~-9,2!DNB.abc"
EndLocal)
I would probably do it the following way, provided that the files to rename are located in immediate sub-directories (YYMM) of the given root directory and nowhere else:
#echo off
setlocal EnableExtensions DisableDelayedExpansion
set "_ROOT=." & rem // (specify path to the root directory)
for /D %%D in ("%_ROOT%\????") do (
for %%F in ("%_ROOT%\%%~nxD\R??????????Account.txt") do (
set "FDIR=%%~nxD" & set "FILE=%%~nxF"
setlocal EnableDelayedExpansion
ECHO ren "!_ROOT!\!FDIR!\!FILE!" "MSF!FILE:~9,2!DNB.abc"
endlocal
)
)
endlocal
exit /B
If you want to check whether both the sub-directory name and the year/month portion of the file names are purely numeric, you could use the following script:
#echo off
setlocal EnableExtensions DisableDelayedExpansion
set "_ROOT=." & rem // (specify path to the root directory)
for /F "delims= eol=|" %%D in ('
dir /B /A:D "%_ROOT%\????" ^| ^
findstr "^[0123456789][0123456789][0123456789][0123456789]$"
') do (
for /F "delims= eol=|" %%F in ('
dir /B /A:-D "%_ROOT%\%%~nxD\R??????????Account.txt" ^| ^
findstr "^R....[0123456789][0123456789][0123456789][0123456789].."
') do (
set "FDIR=%%~nxD" & set "FILE=%%~nxF"
setlocal EnableDelayedExpansion
ECHO ren "!_ROOT!\!FDIR!\!FILE!" "MSF!FILE:~9,2!DNB.abc"
endlocal
)
)
endlocal
exit /B
If you want to check whether the sub-directory name matches the year/month (YYMM) portion of the file names, replace the pattern R??????????Account.txt by R????%%~nxD??Account.txt (for both scripts).
After having verified the correct output of either script, remove the upper-case ECHO commands to actually rename any files!
Basically, both scripts use sub-string expansion to extract the identifier part (KK) from the file names. Since there are variables set and read in the same block of code, delayed expansion is required for that. The second approach does not list the sub-directories and files by standard for loops, it uses the dir command, findstr to filter their names and a for /F loop to capture the resulting output for both sub-directories and files.
I have to manipulate dozens if not hundreds of images fairly often. When I get the images, it's often 1018u182012480d1j80.jpg type filenames, so I can select all of the images, and then hit 'F2' to rename them all to image (1).jpg | image (2).jpg | ... etc. Can someone write me a batch script to remove the parentheses and the spaces in the file names?
If possible, it'd be great if I didn't even have to open it up and edit the batch file to update the current dir, I.E, if it can just use %CD% or something to get the current folder, that would be awesome.
I don't understand batch files at all but here's one I found that will remove the parentheses, but I have to add the sourcedir.
#ECHO OFF
SETLOCAL
SET "sourcedir=C:\.." #Can we make this just find the location?
FOR /f "delims=" %%a IN (
'dir /b /s /a-d "%sourcedir%\*" '
) DO (
SET "name=%%~na"
SETLOCAL ENABLEDELAYEDEXPANSION
SET "newname=!name:)=!"
SET "newname=!newname:(=!"
IF "!name!" neq "!newname!" (
IF EXIST "%%~dpa!newname!%%~xa" (ECHO cannot RENAME %%a
) ELSE (REN "%%a" "!newname!%%~xa")
)
endlocal
)
The script should work if file names/paths does not contain any ! exclamation mark.
Supply a folder path as an argument (see sample calls below). This can be done even by file explorer's drag&drop feature (drag a folder, drop on batch). Read call /? or Command Line arguments (Parameters) for %~1 explanation.
Narrow to only .jpg files using "%sourcedir%\*.jpg" in FOR /f line.

rem remove ) right parenthesis

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 " "

for /r %%a in (*) do (
echo deleting file "%%a" ...
