I have a list of files in a folder that end with .swf.
I want to change all those files from X.swf to X<some number>.swf.
How can I do that?
This little script will change all *.swf files into the equivalent *_42.swf files.
#setlocal enableextensions enabledelayedexpansion
#echo off
for /f %%a in ('dir /b *.swf') do (
set fspec=%%a
set newfspec=!fspec:~0,-4!_42.swf
echo ren !fspec! !newfspec!
)
endlocal
Actually, as it stands now, it will just echo the commands that it wants to execute. Once you're happy they're correct, you can just remove the echo from that renaming line above.
It works by using for /f to get a list of all SWF files and then using string manipulation to:
remove the last four characters (the.swf extension); then
add a new _42.swf extension onto the end.
And, please, make sure you back them up first :-)
You could use the following one-liner directly from the command prompt:
FOR %F IN (*.swf) DO RENAME "%F" "%~nF123.*"
where 123 stands for your number of choice.
Alternatively you could create a batch file and take advantage of its ability to accept parameters. Use the following script:
#ECHO OFF
SET "suffix=%~1"
FOR %%F IN (*.swf) DO RENAME "%%F" "%%~nF%suffix%.*"
Now if the batch's name is renamer.bat, you can invoke it like this:
renamer.bat 2011
and it will add 2011 to the name of every .swf file in the current directory.
Assuming <X> in your description is supposed to be constant and you don't explicitly require a batch script to solve your problem, you can use Windows Explorer as mentioned in an article by Microsoft titled "Rename a file".
Here's a an extract from said article:
"You can also rename several files at one time, which is useful for grouping related items. To do this, select the files [then press F2]. Type one name, and then each of the files will be saved with the new name and a different sequential number at the end (for example, Renamed File (2), Renamed File (3), and so on)."

I regularly have to rename hundreds of files across a subfolder structure. I have been creating a batch file consisting of all my rename commands, and manually pasting this into each subfolder to execute one subfolder at a time. I'd like to revise the batch script so that it executes against all subfolders in one fell swoop, run from the parent directory just once.
My renaming is very manual, and so I need to create a discrete entry for each file. For example, here are three lines:
REN STWP01_00669087* BCBSRI-01849351*
REN BCBSRI-01849357* 2011-12-19_BCBSRI-01849357*
REN STWP01_00669094* BCBSRI-01849369*
I've experimented with the FOR /R command, including trying a separate batch file that calls my renaming batch file (via the CALL command). No luck.
I have to assume that this is simple, but I'm a batch novice, so any help would be appreciated.
Thanks!
#Magoo,
Thanks so much for your response. Your approach is going to be far more efficient than my own so far.
A couple of questions. Please bear with me as I am a total novice with batch commands.
Here's what I did: I saved your code to a .BAT file ("RRename.bat"), modified my filenames as per your instructions and saved those to a text file ("Filenames.txt"), and then run this command from the command line: {RRename.bat Filenames.txt}.
The resulting command windows confirm correct renaming. And so I removed the ECHO and PAUSE commands and re-ran. No luck. Just a bunch of Command windows confirming the directory.
Ideally I'd love to save this as a .BAT file and simply drop this in the top-level directory, together with the data file that contains the old names and new names of the files. And so, a double-click of "RRename.bat" will parse the content of "Filenames.txt" and work its way through all subfolders, renaming wherever matches are encountered. Boom.
To that end:
1. How do I make it so {SET "sourcedir=} indicates the current directory (i.e. the directory in which the batch file is located)? This way I wouldn't ever need to change this variable. (I should note that I am running this script on a network location, which requires me to map the drive, resulting in a different drive letter every time.)
2. How do I hard-code the name of the data file into the script itself? My goal is an easily replicated process minimizing user input (save for the content of the data file).
3. How do I stop the individual command windows from appearing? I'll be renaming thousands of files at a time and don't want to see thousands fo corresponding command windows.
Thank you!
#ECHO OFF
SETLOCAL
SET "sourcedir=U:\sourcedir"
:: read parameters
SET "filename1=%~1"
SET "filename2=%~2"
IF DEFINED filename2 GOTO name
IF NOT DEFINED filename1 GOTO :EOF
:: 1 parameter - must be filename
FOR /f "usebackqdelims=" %%a IN ("%filename1%") DO START /min "ren %%a" "%~f0" %%a
GOTO :eof
:: we have 2 parameters so rename pattern 1 to pattern 2
:name
FOR /r "%sourcedir%" %%a IN ("%filename1%*") DO CALL :process "%%a"
PAUSE
GOTO :EOF
:: Process the filenames and actually do the rename
:process
:: Name of file to be changed - name and extension of %1
SET "changeme=%~nx1"
:: REPLACE up-to-from-pattern with nothing = remainder of name/extension
CALL SET "endpart=%%changeme:*%filename1%=%%"
:: and RENAME...
ECHO(REN "%~1" "%filename2%%endpart%"
GOTO :eof
You would need to change the setting of sourcedir to suit your circumstances.
Revised data file
STWP01_00669087 BCBSRI-01849351
BCBSRI-01849357 2011-12-19_BCBSRI-01849357
STWP01_00669094 BCBSRI-01849369
Aimed at processing the above file, renaming files starting (column1 entries) to start (column2 entries.)
Method:
Run the batch as
batchname filename
This will execute the batch, processing filename
How:
having set the directory name to start processing from, set filename1&2 to the values of the parameters supplied.
If only 1 is supplied, it is the filename, so process it line-by-line and START a new process /min minimised "with the window name in the first set of quotes" and execute this same batch with the data from each line of the file in turn, then finish by going to :eof (end-of-file - built-in to CMD)
The sub-processes all have 2 parameters (eg BCBSRI-01849357 2011-12-19_BCBSRI-01849357) so processing passes to :name. This runs a for /r loop, from the specified source directory, with the name specified from the first column+* and executes :process passing the filenames found as parameter 1.
:process sets changeme to the filename in question, calculates endpart by removing the string filename1 from changeme which will deliver the er, end part.
Then simply rename the supplied filename to the replacement name+that endpart calculated.
The required REN commands are merely ECHOed for testing purposes. After you've verified that the commands are correct, change ECHO(REN to REN to actually rename the files.
The PAUSE is just to allow the proposed changes to be seen. Once the process has been verified, change the PAUSE to EXIT.
AAMOI, running
*batchname* STWP01_00669094 BCBSRI-01849369
for instance, would execute the recursive-rename from STWP01_00669094* to BCBSRI-01849369*
Sadly, "No luck" is meaningless.
I have made a minor, but significant change to the instructions. The PAUSE should be changed to an EXIT after testing.
After testing, the ECHO(... line should become
REN "%~1" "%filename2%%endpart%"
which actually executes the rename. If you've just deleted the line, it would explain the no-visible-result.
Having restored the original code and verified against a small representative dummy subtree, change the echo(... line and test again. The filenames should change. If not, something is dreadfully wrong. Needless to say, this works perfectly happily for me...
Then try again with the PAUSE changed to EXIT. This time, the windows generated will appear on the taskbar and then disappear when the rename for that line of the input file has finished. This will happen once for BCBSRI-01849357 rentwo for instance - not once for each individual file rename occurring.
To hard-code the filename, remove the line
IF NOT DEFINED filename1 GOTO :EOF
and replace
FOR /f "usebackqdelims=" %%a IN ("%filename1%") DO START /min "ren %%a" "%~f0" %%a
with
FOR /f "usebackqdelims=" %%a IN ("YOURFILENAMEHERE") DO START /min "ren %%a" "%~f0" %%a
For the "run from here" command, change
SET "sourcedir=U:\sourcedir"
to
SET "sourcedir=."
. means "the current directory"
If you place thisbatchfilename.bat into any directory on your PATH then you can run the routine simply by executing thisbatchfilename.
You can display your path by typing
path
at the prompt. PATH is the sequence of directories searched by windows to find an executable if it isn't found in the current directory. To chane path, google "change path windows" - experienced batchers create a separate directory on the path for batch files. Sometimes, they name the directory "Belfry".
I have a set of folders already named mm-dd-yyyy (for example 01-01-2014) but they will be more useful named yyyy-mm-dd (for example 2014-01-01). Using dos, how can I rename the folders switching the date parts around?
Assuming that you're talking about cmd.exe rather than the ancient MS-DOS command.com, you can do this reasonably easily(1).
The idea is to iterate over all directories in the current directory, using for /d. Then, for each one that matches a specific pattern (99-99-9999), you can use string manipulation to construct a rename command.
The checking for a correct format can be done with the regular expression capability of findstr.
#echo off
#setlocal enableextensions enabledelayedexpansion
rem Process every file. For each file with a valid format,
rem construct a rename command.
for /d %%a in (*) do (
set full=%%a
call :isvalidfmt !full!
if !res!==true (
set d2=!full:~0,2!
set m2=!full:~3,2!
set y4=!full:~6!
echo ren !full! !y4!-!m2!-!d2!
)
)
endlocal
goto :eof
rem Use findstr regex option to see if file name is correct format.
:isvalidfmt
set res=true
echo %1|findstr /r "^[0-9][0-9]-[0-9][0-9]-[0-9][0-9][0-9][0-9]$" >nul:
if errorlevel 1 set res=false
goto :eof
Note that the script above (let's call it rengen.cmd) simply outputs the rename commands, it does not actually rename the files. That's good practice so you can see what it's going to do before you destroy your directories :-)
To actually rename the files (once you've confirmed it's safe), simply capture the output to another file then run that:
rengen >nextren.cmd
nextren
(1) If you are talking about command.com, I can't help you out there. The command interpreter has come a long way since those bad old days and the one that came with MS-DOS is seriously under-powered.
use dir and export to a file. Take it to Excel and create two columns, one with current name and one with new name and then bring it back to notepad and add RENAME command to each row as a prefix.
RENAME cuurentfilename newfilename is the command syntax.
I am very new to coding and bulk processes but i am looking for a command line SPECIFICALLY for windows command prompt and i am wondering if such a thing exists. So I have a folder containing 111 subfolders, with each subfolder containing between 20 and 40 png image files. Each subfolder is named 001-111 accordingly and the png files are ordered how i want them, however i am looking for a command line that would be able to quickly and efficiently name all the pngs in the folders to the name of the folder followed by the png number in brackets
e.g. for folder 037, i would want the png's to be renamed to: 037(1), 037(2), 037(3) etc...
I am hoping for the best although i am unsure such a code may not be possible or be simply done.
Also if you come up with a code that achieves this process, it would be great if you could reply with the simple command line that i could use rather than a full explanation because i am new to coding and far from fluent with the language or terms or how things work. I know this same process can be achieved by going select all>rename (ctrl a>f2) and renaming to the folder name however i need to use this process frequently and dont want to have to open each folder, i would rather have a command line for cmd that would do it swiftly
Thank you and a simple answer would be greatly appreciated
#ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION
SET "parentdir=u:\parent"
FOR /l %%a IN (1001,1,1111) DO (
SET dir=%%a&SET "dir=!dir:~1!"
FOR /f "delims=" %%i IN ('dir /a-d /b "%parentdir%\!dir!\*.png" 2^>nul') DO (
ECHO REN "%parentdir%\!dir!\%%~nxi" "!dir!(%%~ni)%%~xi"
)
)
GOTO :EOF
Test results:
Starting directory :
u:\parent\001\1.png
u:\parent\037\1.png
u:\parent\037\2.png
u:\parent\111\999 with spaces in name.png
Script response
REN "u:\parent\001\1.png" "001(1).png"
REN "u:\parent\037\1.png" "037(1).png"
REN "u:\parent\037\2.png" "037(2).png"
REN "u:\parent\111\999 with spaces in name.png" "111(999 with spaces in name).png"
Obviously, you'd need to replace the value assigned to parentdir with your actual target directory name.
The script will report the renames it proposes to do. To actually invoke the rename remove the ECHO keyword.
I would create a batch file like so:
renamepng.bat:
cd %%1
if ERRORLEVEL 1 goto end
for %f in *.png do mv "%f" "%%1(%f).png"
cd ..
:end
This will attempt to cd to the directory name provided on the command line, abort if that fails, then rename all the .png files and return to the previous directory
then call it like so:
for %d in ??? do call renamepng.bat %d
which will loop through all 3-character file and directory names in the current directory, can call the batch file on each one. Using call instead of just the batch file name causes execution to return to the loop when the batch finishes.
Note: There is no need to use batch per say, but I am just familiar with batch, Powershell would be better I imagine, so if there are easier solutions for this problem in powershell, please shout!
I have the arduous task of testing our DR backups for all our clients, that is, mounting ShadowProtect Snapshots latest incremental, writing and reading a file, them unmounting the image. The actual ShadowProtect part of batch is fairly simple but I would like to design a batch that can automate this.
Essentially my question is:
How in a batch file can I firstly, enumerate files in a folder, and then place a specific part of a given filename into a variable?
Reason being ShadowProtect incrementals have a naming convention such like:
SERVERNAME_DRIVELETTER_b00X_i000x - whereby b = base image, i = incremental number
I need to mount the latest incremental image, therefore need to parse the folder and find the latest incremental image, based on the number following the i in the filename.
Is this possible in batch?
Thanks!
Something like this should work:
#echo off
setlocal EnableDelayedExpansion
for /f "delims=_ tokens=1-4" %%f in ('dir /b *_*_*_*') do (
set servername=%%f
set driveletter=%%g
set base_image=%%h
set increment=%%i
)
echo !servername!
echo !driveletter!
echo !base_image!
echo !increment!
endlocal
If you have several matching files and want to do something with all of them, you need to put the processing code inside the loop.
Edit:
for /f: process either a file or the output of a command enclosed in single quotes
delims=_: fields in the processed content are separated by underscores
tokens=1-4: assign the first four tokens to the parameters %%f through %%i (first parameter is the one given in the for statement)
dir /b *_*_*_*: list all file where the name contains at least 3 underscores with just their file name (the output of this command is processed by the for loop)
setlocal EnableDelayedExpansion: expand variables at run time (otherwise assigning the parameters to variables wouldn't work)
For further details see help for and help dir.
You could always use vbscript or jscript. It is much more powerful than batch files. Also jscript and vbscript hosts are available also on machines that don't have powershell!
Link for enumeration:
http://www.techimo.com/forum/webmastering-programming/100453-recursive-javascript-list-all-files-folders-given-folder.html
Jscript string reference:
http://msdn.microsoft.com/en-us/library/bxsyt3yc(v=vs.80).aspx
You should be able to combine the two.
you run your jscript (I prefer jscript to vbscript because of its resemblance to javascript)
cscript scriptname
I have many folders in a directory that contain various files. Each filename begins with XXX_ where XXX could be the name of the folder the file is in. What I am needing to do is to go through all those folders and delete any file where XXX is the name of the folder that file is in.
Please have an eye out this question: Iterating through folders and files in batch file?.
I think this should help you.
Please let me know if you need further assistance.
EDIT #1
The joker character in DOS command line is *. Then, while searching a directory for certain files, you may consider your regular expression, that is, your XXX_, and complete it with *, this shall return only the files for which you're looking for.
This means that instead of *.zip pattern in one of the FOR loops given the linked question, your first FOR loop should contain your directory name, then take this variable concatenated with the * character to obtain only the files you're looking for.
For example, consider trying the following:
dir /s XXX_*.*
This should return only the files you're interested in, given the right folder name.
EDIT #2
Thanks for having precised your concern.
Here is a code sample that, I do hope so, should help. Now I know you say you have the looping correct, so that perhaps only piece of this code might be needed.
#echo off
setlocal enableextensions enabledelayedexpansion
for /F "delims==" %%d in ('dir /ogne /ad /b /s .') do (
for /F "delims==" %%f in ('dir /b "%%d\%%~nd_*.*"') do (
echo %%d\%%f
)
)
endlocal
This works and lists the files contained in subfolders from the current (.) folder.
I have tested it from the following folder:
C:\Docume~1\marw1\MyDocu~1\MyMusi~1
Where a 'XXX' folder is contained. This 'XXX' folder contains the following files:
Copy of XXX_blah.bmp;
XXX_blah.bmp;
XXX_1234.ppt;
XXX_textfile.txt.
From this structure, the output is:
C:\Docume~1\marw1\MyDocu~1\MyMusi~1\XXX\XXX_blah.bmp
C:\Docume~1\marw1\MyDocu~1\MyMusi~1\XXX\XXX_1234.ppt
C:\Docume~1\marw1\MyDocu~1\MyMusi~1\XXX\XXX_textfile.txt
I then suspect that putting a del instruction instead of an echo command shall do the trick. This means that to isolate the foldername itself from its path, you need to use the ~n instruction with your folder variable name like %%~nd, where your iterating folder variable name is %%d.
Furthermore, you could even use a parameterized batch file in the process, instead of hardcoding it, that is, if your 'set YourFolder =...' is part of your production code. This could look like:
#echo off
setlocal...
set root = %1
set root = %root:~1%
set root = %root:~0,-1%
...
endlocal
Instead of having '.' as pictured in my first FOR loop, your would replace it with "%root%" in order to consider your command line parameter instead of a hardcoded filepath.
I do help this helps, sincerely!
As Ron says, since the question is tagged "windows".
EDIT:
Ron's answer, which seems to have disappeared!, was to use del /s
EDIT2:
OK, it's valid only for file names, not for directories. For the directories you'd have to use something like sketched below.
Additional info: when you want to do the same thing recursively to files in a directory tree, and (unlike del) there's no command that already does the traversing for you, you can use the /R option of the for command.
To see the for command's docs, do e.g. start "for-help" cmd /k for /?.
