I have a bunch of video files with names like so:
6592110904-Ivory-2.mp4
6592280588-Cornflower.mp4
6592321696-Ballet Pink.mp4
I want to rename them to get rid of everything after the first hyphen so they end up like:
6592110904.mp4
6592280588.mp4
6592321696.mp4
How do I go about doing this?
Please put the code below in a bat file, place it in directory with mp4 files. Before running real renaming, please remove "echo" before "move". please be carefull with renaming bacause (theoretically) it is possible to have same name for different files.You'll be prompted to confirm if you want to override the old one.
Code splits each filename after dash and renames the file taking first item. Good luck.
#echo off
for /F "tokens=1,* delims=-" %%a in ('dir /A-D /B "*.mp4"') do (
echo move "%%a-%%b" "%%a%%~xb"
)

My university is using a proprietary system that outputs data in a very specific way in which each "module" is output into folders following the structure (4 digit numeral) - (name of module)
ex: 5574-CHEM104
I need to remove the name and hyphen so that only the numeral remains:
5574-CHEM104 > 5574
The problem is that there's thousands of these folders and there's no way I could do it by hand. I'm having difficulty trying to automate the process, so if anyone could at least point out a command I could look into it would help immensely
I've tried the REN command, putting "REN 5574-CHEM104 5574", but it only works for one folder. There's thousands of folders, each with different numerals, under "CHEM104", for example, and I need for the program to rename the folder no matter the original name into the first 4 original numerals, which I can't figure out. Thanks!

Always verify against a test directory before applying to real data.
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 directories.
Using a list of the directory-names, names only (/b) and directories only (/ad), tokenise the name using - as a delimiter and execute the rename using the token assigned to %%o (default is first token)
I have two photo folders taken with different cameras, and want to merge them by date, and then view the combined directory in date sequence. I have merged them, and the directory dates look good, but the tools I use insist of showing the photos in name sequence, which is not what I want. I thought of doing a batch rename function to make the date part of the file names, using a bat file, but the DOS DIR command doesn't seem to use this date - if I do
for /f "skip=5 tokens=1,2,4,5* delims= " %%i in ('dir /a:-d /o:d /t:c') do (
etc., most of the file dates are correct, but some of the files seem to be using the "created date" of the directory.
Maybe there is a simple solution as this must be a common problem, but I haven't found a good solution - short of doing a laborious manual rename of some 700+ files!
Help would be appreciated!

for /f "tokens=1*delims=[]" %%a in ('dir /b /a-d /od /t:c^|find /v /n "" ') do echo ren "%%b" "%%a%%~xb"
Perform a directory scan of the source directory, in /b basic mode /a-d without directories in date order selecting created-date, number in brackets each line that doesn't match an empty string and assign each filename found to %%b and the number to %%a
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.
Note: filenames that begin [ or ] will be processed incorrectly. If an existing file has a name which belongs to the target nameset (ie 1.? 2.? etc.) then simply prefix the target name with a prefix that doesn't already exist, eg ren "%%b" "new_%%a%%~xb" (where there are no existing files named new_*)
I'm not sure about Win7's capability when displaying files using the utility you are using (Explorer?) Win10 has the capability of selecting display by creation-date (select sort by then creation-date)
If you are sure you are sorting by creation-date then probably you'd need to select some other sorting scheme (change t:c to t perhaps)
If there are filenames that aren't being converted, then you are probably adding files (called img*) to a directory that already contains files named 1,2,3... - in fact, it's difficult to see how that phenomenon could happen otherwise.
Change "%%a%%~xb" in the rename command to "xyz%%a%%~xb" and you should find that the files are then all renamed xyz1,xyz2,xyz3 etc. If you then reprocess the files with xyz removed, the names should become 1,2,3 with no omissions.
I would like to rename my video files as per the resolution they are in, e,g for a video 'bla bla.mp4' in 1080p, I would like to rename it to 'bla bla [H.264 1080p]. The script should automatically be able to detect the resolution of the video, and also if the file has been already renamed it should not rename it.I wasn't able to find a way to check for the resolution, so I tried to use this for 1080p files:
FOR /r %%a in (*.mp4) DO (IF EXIST *[H.264*.mp4 (
ECHO Already done)
ELSE (
REN "%%~a" "%%~na [H.264 1080p].mp4"))
But what it does is it checks for the same file again and again which has already been renamed and therefore the reply always is 'Already done'.
This question is beyond the scope of an SO question. Nevertheless I will answer it, because today is sunday.
download and install mediainfo command line version
add the path to the mediainfo binaries to your system or user PATH environment variable
copy the rename script, replace the path to your video folder, there is a safety echo before the rename command, remove it if the output looks good
the script tests for already-exists and already-processed files (suggested by Peter Wright)
rename script:
#echo off & setlocal
cd X:\video\path
for /f "delims=" %%i in ('dir /b /a-d *.mp4') do (
set "fnameo=%%~ni"
set "fnamee=%%~xi"
set "Height="
for /f "delims=" %%j in ('mediainfo "--Inform=Video;%%Height%%" "%%~i"') do set "Height=%%j"
setlocal enabledelayedexpansion
call set "selftest=%%fnameo:[H.264 !Height!p]=%%"
if "!selftest!" equ "!fnameo!" if not exist "!fnameo! [H.264 !Height!p]!fnamee!" (
echo rename "!fnameo!!fnamee!" "!fnameo! [H.264 !Height!p]!fnamee!"
)
endlocal
)
output example:
rename "Handbrake.0.9.8.mp4" "Handbrake.0.9.8 [H.264 800p].mp4"
rename "Hybrid.2012.10.21.1.mp4" "Hybrid.2012.10.21.1 [H.264 800p].mp4"
rename "Womble.mp4" "Womble [H.264 1080p].mp4"
There was a very similar question here:
Windows batch file renames filename unexplainably in FOR loop
Peter Wright had posted a solution with a very good explanation:
Try
for /f "delims=" %%a in (' dir /b /a-d *.mp3') do ( The problem is
that your original syntax finds the next filename - which finds your
renamed file since the new filename (with the prefix) is logically
'greater than' the old.
Using dir builds a list of filenames, and processes the list once it
has been completely built - hence the list doesn't vary as the files
are renamed.
The "delims=" clause ensures that the default parsing of the filename
is ineffective - otherwise, the filename would be interpreted as a
series of [space-separated] tokens.

The IF EXIST conditional will always pass after the first file is renamed, since as written it will check for the existence of any file in the directory that contains "[H.264" in the file name, not just %%a.
Consult Batch file: Find if substring is in string (not in a file) to learn how to find "[H.264" in %%a, which would cause the intended result.
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.
i have an edited version of a config file specific for my machine.
i have the same config file in multiple different directories in my development folder.
i want to, in a single bat file, replace all instances of this file with my edited one.
So in pusedo code:
Take C:\edited.config and copy to C:\Projects\ /s wherever original.config is found
i want the final file to have the name of original.config, not edited.config
so i am guessing i need some combination of a FOR, a rename and copy or something like that
is this easier to do in Powershell?
can anybody help?
Thanks
I blogged about this a little bit ago at http://jamesewelch.com/2008/05/01/how-to-write-a-dos-batch-file-to-loop-through-files/
I think your solution will look something similar to (below is untested but used to show general idea)
for /f %%a IN ('dir /b *.config') do copy c:\master.config %%a
There's probably a switch there on the copy to suppress file overwrite warnings, but I don't remember what the switch is. This will copy your master.config and overwrite your local file (variable of %%a).
I'm amazed what DOS batch file experts make work. Since I'm not one of them, I take an approach that's pragmatic for me. It might work for you as well.
Get a list of destination folders
C:
Cd\
Dir original.config /s > original.bat
Edit original.bat in your favorite text editor (I like Notepad++)
Search for "original.config" and replace with "" (empty string)
Insert the text "Xcopy C:\edited.config " at the front of each line
Proof-read the result to be sure it's what you want. If you're not sure put an "Echo " in front of each line for a dry run.
Run the batch file.
#echo off
C:
cd \Projects
FOR /F "tokens=*" %%G IN ('DIR /B /S original.config') DO xcopy /y c:\edited.config %%G
