Rename multiple images in a folder using a batch file - file

I have a folder full of images which have a format filename.com_XXX_IMG_000.jpg. The issue comes because the file name has a .com in it, it confuses the the software that I am using to upload it to a webspace.
I need to create a batch file that gets all the images in a folder and renames all of them from filename.com_XXX_IMG_000.jpg => filename_XXX_IMG_000.jpg.
Any help would be greatful, thanks in advance.

Since you want to do it in a batch file:
#echo off
for /f "delims=. tokens=1,2,3" %%f in ('dir /b *.jpg') do (
setlocal enabledelayedexpansion
set part=%%g
if "!part:~0,3!"=="com" (
set oldname=%%f.%%g.%%h
set newname=%%f.!part:~4!.%%h
echo "!oldname!" -^> "!newname!"
ren "!oldname!" "!newname!"
)
endlocal
)
A few notes
for loop variables are single letter, like this: %f
in a batch file, the % must be escaped, so %f becomes %%f
delims=. splits the filenames at the ., in your case into three parts
tokens=1,2,3 returns three variables containing the individual name parts (%f, %g and %h)
enabledelayedexpansion switches on dynamic variable handling
you can do string manipulation with variables: %foo:~0,3% returns the first three characters of %foo%.
with delayed expansion enabled, you can access variables that change their values by using ! instead of %
the > must be escaped or echo won't print it, hence ^>
read some more on String Manipulation in DOS

read HELP FOR and try the following....
#echo off
setlocal enabledelayedexpansion
for %%a in (*.jpg) do (
set fn=%%~na
set fn=!fn:.com=!
echo REN "%%a" "!fn!.jpg"
)
you need to enable delayed expansion because you need to expand a variable inside the for loop.
the loops iterates over all the jpg files in the current directory and for each file it extracts its filename using the ~n syntax, and then it removes all the occurences of .com by replacing them with an empty string. Read HELP SET
after careful testing, remove the echo command

Batch - Looping in 'FileNames_Constant.Ext' , and Print 'FileNames' as an Output

I've got some *.Xml files in a directory and its sub-directories. I need to loop through the XML files which have a specific constant at the end of their file name, and then echo/print their names without the constant part nor the extension (.Xml).
For example: these are the file names I have:
FileAAA_Constant.Xml
FileBBB.Xml
FileCCC.Xml
FileDDD_Constant.Xml
And this is the output I need:
FileAAA
FileDDD
I've tried this command:
For /R %%X in (*_Constant.Xml) do echo %%~nX
Which outputs this:
FileAAA_Constant
FileDDD_Constant
As you can see, it has removed the extension only, while I need to remove "_Constant.Xml" as well.
This works if the file names contains only one underscore, as indicated in your example:
for /F "delims=_" %%X in ('dir /S /B *_Constant.Xml') do echo %%X
If the desired file names may contain more than one underscore, use Pokechu22's answer.
Fairly easy if the exact length of the phrase is known; you just need to use the %var:~0,-3% syntax. Since "_Constant" is 9 chars long, you would want %var:~0,-9%, which takes text from the start (0) to 9 chars from the end (-9). Aditionally, delayed variable expansion also must be enabled with setlocal ENABLEDELAYEDEXPANSION for this to be run inside of your For loop.
Here's a full example:
#Echo off
setlocal ENABLEDELAYEDEXPANSION
for /R %%X in (*_Constant.Xml) do (
set FileNameTemp=%%~nX
echo !FileNameTemp:~0,-9!
)
Note that if you have a file named just _Constant.xml, this will produce "ECHO is off." rather than "" (no output). This can be solved by changing echo !FileNameTemp:~0,-9! to echo. !FileNameTemp:~0,-9!, but that puts a space before each output.
Here's the loop alone:
for /R %%X in (*_Constant.Xml) do (
set FileNameTemp=%%~nX
echo !FileNameTemp:~0,-9!
)

Batch renaming last few characters of files

I'm trying to create a batch file that would rename a bunch of files in a folder. These files would have a naming of something like: blah(lol).txt. There will always be a four letters, followed by an open bracket, three letters, and finally a close bracket.
I want the batch file to remove the bracketed part of the name of the file, ie. rename the file without the bracketed part.
for %%i IN (*.txt) DO (set name=%%~ni
set name2=%name:~1,4%
ren %%i %name2%)
Why doesn't this work?
Magoo provided an explanation as to why your script failed, as well as a working script.
But in your case, there is no need for a script. A simple REN command is all that is needed:
ren "????(???).txt" "????.*"
#ECHO OFF
SETLOCAL
SET "sourcedir=U:\sourcedir"
FOR /f "tokens=1,2,3delims=()" %%a IN (
'dir /b /a-d "%sourcedir%\*(*).*" '
) DO ECHO REN "%sourcedir%\%%a(%%b)%%c" %%a%%b%%c
GOTO :EOF
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.
Within a block statement (a parenthesised series of statements), the entire block is parsed and then executed. Any %var% within the block will be replaced by that variable's value at the time the block is parsed - before the block is executed - the same thing applies to a FOR ... DO (block).
Hence, IF (something) else (somethingelse) will be executed using the values of %variables% at the time the IF is encountered.
Two common ways to overcome this are 1) to use setlocal enabledelayedexpansion and use !var! in place of %var% to access the changed value of var or 2) to call a subroutine to perform further processing using the changed values.
simple but works from the folder with the files to be renamed.
#echo off
title Rename Bat
echo This bat must be in the folder that
echo contains the files to be renamed.
:begin
echo Enter File Name
set /p old=
echo Enter New Name
set /p new=
ren "%old%" "%new%"
echo File Renamed
ping -n 3 127.0.0.1 >NUL
goto begin
a much simpler approach ... try a for loop that cycles through all files in your folder
I'm going to use lol as an example of three letter word inside brackets as stated in your question
#echo off
for %%a in (*) do (
rename "%%a" "%%a(lol).exe"
)
to use this batch file you have to place it in the folder containing the files you wanna rename

Batch Script assistance needed

Happy Friday Think-Tank!
I need some assistance with a Batch .BAT script. Specifically I need help with some "IF statement syntax"
I have a script that is renaming files. There are two files, one ending in four digits and the other ending in five digits. The files will be renamed with variables I have already pre-set earlier within my script.
So here is a scenario: We have two files in a directory located at
c:\Users\username\Desktop\test-dir
There are two files within test-dir:
file1.12345
file2.1234
A four digit ending is one variable type (VAR1), whereas a file ending in five digits is another variable type (VAR2).
I need an if statement to:
a) read all the files(s) with the chosen directory (without using a wildcard if possible).
b) determine based on the number of digits after the "." which variable to use.
c) once making that determination rename the file with the appropriate variables.
The final re-naming convention is as so: yyyymmddtype.1234/12345
So basically it would use the datestamp variable I already created, the type variable I already created to be injected by the if statement, and append with the original ending digits of the file.
I know this seems like a lot, but I am more so a bash script guy. I have all the elements in place, I just need the if statement and what feels like a for loop of some kind to tie it all together.
Any help would be great!
Thank you!
Sorry, not the option you where asking for. Instead of iterating over the full list checking each file for extension conformance, iterate over a list of patterns that will filter file list, renaming matching files with the asociated "type"
for %%v will iterate over variable list, for %%a will split the content of the variable in pattern and type, for %%f will generate the file list, filter with findstr using the retrieved pattern and rename matching files with the corresponding "type"
Rename command is preceded with a echo to output commands to console. If the output is correct, remove the echo to rename the files.
#echo off
rem Variables defined elsewhere
set "folder=c:\somewhere"
set "timestamp=yyyymmdd"
rem Rename pattern variables in the form pattern;type
set "var1=\.....$;type1"
set "var2=\......$;type2"
set "var1=\.[^.][^.][^.][^.]$;type1"
set "var2=\.[^.][^.][^.][^.][^.]$;type2"
setlocal enableextensions disabledelayedexpansion
for %%v in ("%var1%" "%var2%") do for /f "tokens=1,* delims=;" %%a in ("%%~v") do (
for /f "tokens=*" %%f in ('dir /a-d /b "%folder%" ^| findstr /r /c:"%%~a"') do (
echo ren "%folder%\%%~f" "%timestamp%%%~b%%~xf"
)
)
endlocal
#ECHO OFF &SETLOCAL
set "yyyymmdd=yyyymmdd"
set "VAR1=VAR1"
set "VAR2=VAR2"
for /f "delims=" %%a in ('dir /b /a-d^|findstr /re ".*\....."') do echo(ren "%%~a" "%yyyymmdd%%VAR1%%%~xa"
for /f "delims=" %%a in ('dir /b /a-d^|findstr /re ".*\......"') do echo(ren "%%~a" "%yyyymmdd%%VAR2%%%~xa"
remove echo( to get it working.
If I understand you then this will rename the two files using preset variables for each one:
for %%a in ("%userprofile%\Desktop\test-dir\*") do (
if "%%~xa"==".12345" ren "%%a" "%variableA%-%variableB%%%~xa"
) else (
ren "%%a" "%variableC%-%variableD%%%~xa"
)
)

Modifying For loop variables cmd

Thing I want to do is to filter out specific video file extensions from a text file containing various video file names e.g filename.txt contents are
Red.mp4
Yellow.mp4
Blue.mp4
Orange.wmv
Purple.wmv
Now I will parse this file for .mp4 only & utilise 'for parameter' to make several .txt files each containing particular code for a particular file. In other words will create number of files same as number of .mp4 video in filename.txt My code
::==
#echo off
setLocal EnableDelayedExpansion
for /f "tokens=* delims= " %%a in ('type filename.txt ^|findstr ".mp4"') do (
set /a n+=1
echo >myfile!n!.txt
set v!n!=x264 --crf 23 --level 3.1 --tune film --o "%%a" "%%a.mkv"
)
set v
pause
::==
I have two problems:
How do I modify %%a to have its .mp4 string removed because when I apply "%%a.mkv" a file will be named *.mp4.mkv and I don't want that and .mp4 can be typed manually like --o "%%a.mp4" "%%a.mkv"
Provided that required txt files are already created how do I pass variables v1,v2,v3... to its respective text file I tried with
echo %v!n!% > >myfile!n!.txt
within loop but it didn't work, so plz advice
I don't see any need to create an array of variables with one loop, and then add the content to files in a 2nd loop. Simply do everything in one loop.
Also, there is no need to create an empty file, and your attempt to do so is incorrect - it adds the line ECHO is off. to each file. To echo a blank line you should use >filename ECHO(. To create an empty file use copy nul filename.
This is unlikely to be a concern, but it is possible for a filename to contain !. Expansion of a FOR variable containing ! will be corrupted if delayed expansion is enabled. The issue can be solved by toggling delayed expansion on and off within the loop, but there is another solution: use another FINDSTR command to prepend each line with the line number, and then parse the line number and file name with the FOR loop. This eliminates the need to increment a counter and eliminates the need for delayed expansion.
The ~n FOR variable modifier is used to get the name without the extension.
#echo off
for /f "tokens=1* delims=:" %%A in (
'findstr /lie ".mp4" filename.txt^|findstr /n "^"'
) do (
>"myfile%%A.txt" echo x264 --crf 23 --level 3.1 --tune film --o "%%B" "%%~nB.mkv"
)

Filenames renaming using .bat?

Heythere.
I need your guys help with file renaming using a .bat file.
I got multiple files that I need to be cropped after specified character number.
For exmample, I want to crop name of the files after their fifth character, this way
filename.exe > filen.exe
anothername.exe > anoth.exe
absolutelydifferentname.exe > absol.exe
And, if possible, I'd like to know how to do the opposite. I mean, leaving the certain # of characters at the end, cropping from the beginning of the filename.
Thank you.
If you want to do it in a batch file, the following should work:
#echo off
setlocal ENABLEDELAYEDEXPANSION
for %%i in (<Directory name here>\*) do (
set filename=%%~ni
ren "%%~i" "!filename:~0,5!%%~xi"
)
endlocal
If you wish to change the number of characters used to construct the final filenames, change the "5" in ren "%%~i" "!filename:~0,5!%%~xi".
To take the last 5 characters try: ren "%%~i" "!filename:~-5!%%~xi"
For all except the first 5 characters: ren "%%~i" "!filename:~5!%%~xi"
The Iridium solution will fail if any file name contains the ! character because expansion of %%i will fail if value contains ! and delayed expansion is enabled. This is easily fixed by toggling delayed expansion on and off within the loop.
The explicit disabling of delayed expansion at the top is normally not needed. But it is possible for delayed expansion to already be enabled at the start of a batch file, so I included it just to be safe.
#echo off
setlocal disableDelayedExpansion
for %%F in ("<Directory name here>\*") do (
set "full=%%F"
set "name=%%~nF"
set "ext=%%~xF"
setlocal enableDelayedExpansion
ren "!full!" "!name:~0,5!!ext!"
endlocal
)
Just incase this is a once-off, or some other manual scenario, have a look at
