Batch Script To Identify Missing Numerical File Name - batch-file

I have a custom service that automatically generates files every 60 mins into a particular directory with part of the filename incrementing numerically, Eg:
File_00004.job
File_00003.job
File_00002.job
File_00001.job
Currently I have an issue where on occasion a file isn't generated, which results in gaps in the file sequence. This issue then causes a number of issues if not identified ASAP.
I'd like a batch file to identify if I have a gap in the file name sequence.
Tried looking for solutions from existing posts, but haven't found something that fits, so apologies if this has been covered elsewhere.

#ECHO OFF
SETLOCAL enabledelayedexpansion
rem The following settings for the source directory, destination directory, target directory,
rem batch directory, filenames, output filename and temporary filename [if shown] are names
rem that I use for testing and deliberately include names which include spaces to make sure
rem that the process works using such names. These will need to be changed to suit your situation.
SET "sourcedir=u:\your files\t w o"
SET "mask=file_??????.job"
SET "lowest="
SET "highest="
FOR /f "delims=" %%a IN (
'dir /b /a-d /on "%sourcedir%\%mask%" '
) DO (
IF NOT DEFINED lowest SET "lowest=%%~na"
SET "highest=%%~na"
)
SET "lowest=%lowest:*_=1%"
SET "highest=%highest:*_=1%"
ECHO checking range %lowest:~1% to %highest:~1%
:: See whether an entry in the range is missing; report&create an empty file if so.
FOR /L %%a IN (%lowest%,1,%highest%) DO SET "name=%%a"&SET "name=file_!name:~1!.job"&IF NOT EXIST "%sourcedir%\!name!" echo !name! missing&(copy nul "%sourcedir%\!name!" >nul)
GOTO :EOF
Alternative structure for the for /L loop:
FOR /L %%a IN (%lowest%,1,%highest%) DO (
SET "name=%%a"
SET "name=file_!name:~1!.job"
IF NOT EXIST "%sourcedir%\!name!" (
echo !name! missing
copy nul "%sourcedir%\!name!" >nul
copy "d:\path to\template.file" "wherever\!name!" >nul
copy "d:\path to\template.file" "anotherplace\!name!" >nul
echo Batch is fun and powerful
copy "d:\path to\template.file" "a third place\!name!" >nul
)
)
The critical point is the positioning of the ( - must be directly after and on the same line as do or else or the logical comparison clause of if and must be matched by a ) (which doesn't need to be on its own line - I find it easier that way, to align indentation.) )s that are not intended to close a block need to be escaped with ^, thus: ^)

How to batch transfer rename?

There are two folders holding equal amounts of files between them.
I'd like to apply the names from one set ; to the other set of files in no particular order. Inherit the name, but retain the extension .
Input files are .bmp Output files are .ini ( has a gear symbol ).
Example :
folder 1- Flowers.bmp ; folder 2- blank.ini
. To this:
folder 1- Flowers.bmp ; folder 2- Flowers.ini
There would be more files , but equal .
The .ini files are all copies . So they may have a generic name and numbered if that matters to know . Those would all receive one name each from the other .bmp files in the other folder.
Normally I have both folders situated on the Desktop .
I make sure both folders have equal number of files between them . That would be a constant .
I'm trying to stream line some menial repetitive daily tasks .
I did search and what I have found does not really help.
#ECHO OFF
SET "vers=%~1"
IF "%vers%" == "" SET /P "vers=Enter Vers: "
FOR %%F IN (file_XX_*.*) DO CALL :process "%%F"
GOTO :EOF
:process
SET "name=%~nx1"
SETLOCAL ENABLEDELAYEDEXPANSION
SET "name=!name:_XX_=_%vers%_!"
RENAME %1 "%name%"
ENDLOCAL
Hoping to find a solution to this finally .
Ok, here is a slightly long version, but it makes sure it gets the content of each folder.
Note You must ensure that the path to both folders are correctly specified in the third and fourth line:
#echo off
setlocal enabledelayedexpansion
set "source=%userprofile%\Desktop\folder 1"
set "destination=%userprofile%\Desktop\folder 2"
set /a num=0
for %%a in ("%source%\*") do (
set /a num+=1
set "fr!num!m=%%~na"
)
set /a oldn=!num!
set /a num=0
for %%b in ("%destination%\*") do (
set /a num+=1
set "to!num!r!=%%~nxb"
set "ext=%%~xb"
)
pushd "%destination%"
for /l %%i in (1,1,!oldn!) do ren "!to%%ir!" "!fr%%im!%ext%"
popd
pause
You can remove pause at the bottom of the script, once you are happy with the output.
This is not the most effective way, but considering your limited batch experience, I guess an understandable approach is better than an optimized one (using array-like variables).
#echo off
setlocal enabledelayedexpansion
(for %%A in ("folder 1\*.bmp") do echo %%~nA)> "%temp%\names.txt"
<"%temp%\names.txt" (
for %%A in ("folder 2\*.ini") do (
set /p "name="
ECHO ren "%%A" "!name!.ini"
))
The first for loop creates a list of the desired names (from Folder 1). The modifier %%~nA returns the name only.
The second for processes each file in Folder 2 and takes a name from the previously generated file for each file. This depends on the fact that the number of files in both folders are the same, else you may get undesired results.
I disabled the actual ren command by just echoing it. Check the output and only when you are satisfied, remove the ECHO.

Batch unzip files in child folders, then copy specific files to network folder based on number in file name

I am a serious newbie at creating batch files and am hoping someone can help me. One of our staff receives zipped pdf docs by email, which she copies to a folder on her desktop. Within that folder, I would like for her to run a batch script that will
A. Unzip the zipped contents into a network directory, i.e. \server\contracts
Under this directory, the process will create folders for each group of contracts, i.e. \server\contracts\Masterson (The name of this will be same as zipped file name).
B. Then the batch process should copy a select few of the pdf documents into a network directory based on the filename. Each file contains a number, which will go in the following manner: Masterson + 1.pdf >> \server\contracts\Item1 and \server\contracts\Item2, etc. Masterson + 1.pdf will go into \server\contracts\Item1 without a folder name, as will Paisley + 1 certificate.pdf and Johnsonville + 1 document.pdf.
The problem is that the companies do not follow instructions and the number can be at the beginning, middle, or end of the file name. Also, unfortunately, there are spaces in the name of the zipped file and the pdf documents. Currently, we are only copying 4 filenames into separate directories for other people to review and validate.
Below is what I did so far looking around this site:

Of course this doesn't work. Please help!
Well - bravo for the attempt! And so close...
Let's take the first part
for /R "delims=\\server\contracts\RECEIVED 2017-18 APPLICATION" %%I in ("*.zip") do (
"%ProgramFiles(x86)%\7-Zip\7z.exe" x -y -o"%%~dpnI" "%%~fI"
)
What's wrong here is that the delims clause is only usable in for /f. for /r always delivers the entire filename to the metavariable %%I.
On my system I use %server%\u for testing - u is a shared resource on the server assigned to U:\ on server.
for /R "\\%server%\u\contracts\RECEIVED 2017-18 APPLICATION" %%I IN ("*.zip") do (
"%ProgramFiles(x86)%\7-Zip\7z.exe" x -y -o"%%~dpnI" "%%~fI"
worked happily for me - delivering the extracted files to "u:\contracts\RECEIVED 2017-18 APPLICATION"
The second part of your code is examining "C:\Users\eartha.kitt\Desktop\Test" not "\%server%\u\contracts\RECEIVED 2017-18 APPLICATION" - very sensibly assigned to a variablename for easy adjustment.
Here's my modified code:

goto:Loop
First, I set up terminatefilename so that creating this file will terminate the batch (it's an infinite loop by design in your code)
Next, I overrode your inputfolder name to suit my system.
Then the output directories. I adjusted their names to suit my system. Note that batch is largely case-insensitive, so setting Output8A and Output8a is setting the same variable. The only time that batch commands are case-sensitive is the metavariable (loop-control variable) in a for statement.
Then I inserted a line to create the destination directories. This uses a set command to list the variables starting output in the format Output1=\\%server%\u\contracts\ITEM 1 17-18 CERTS (where server will have been resolved). The command reads the output of the set command, uses = as the delimiter and assigns output1 to %%b and \\%server%\u\contracts\ITEM 1 17-18 CERTS to %%c. We want to make sure the directory %%c exists, so we make it with an md command and ignore complaints that it already exists with 2>nul.
Next the for/f. for /f reads each line of (thisfilename) or ("this literal value") or ('the output of this command') but when you need to read a from a file whose name must be double-quoted beacuse it contains spaces, then the syntax is for /f "usebackq"... (idontknow) or ("this filename containing spaces") or ('ive no idea whatever') or (`the output of this command`)
So there's no need to use usebackq -- in fact, it's counterproductive.
The delims=| is optional and could be replaced by delims= as the output of a dir command will never contain | (illegal in a file or directoryname). You do need the delims clause however, as the default delimiters include Space and the default tokens is 1 so only the first string of each line output up to the first space will be assigned to %%a.
Hmm - you've remmed-out a for/r. Sadly, the target directory in the for /r can't be a metavariable.
Next, I've cleared a copied flag saying "so far, this file has not been copied"
Next, set fichier to the name-part only of the filename. Since you are using .pdf as a filter, each name output by the for/f will be a full-filename, ending in .pdf
Next, almost-correct with the battery of if statements. The /i makes the comparison case-insensitive so that it will cope with both 8a and 8A. The strings on both sides of the == must be identical to pass the == test, so you need a 3-character string in the 8 tests.
You've evidently been experimenting with the copy command and trying to feed it with appropriate strings. %%~a strips %%a of any enclosing quotes. %%a won't have enclosing quotes - just the fullfilename, so this does nothing in this instance. %InputFolder%\~%%a concatenates the values from InputFolder,"\~" and %%a - which means "%inputfolder%\~%inputfolder%\filenameandextension of %%a". The last two would be resolved to the same, bar the ~.
Since the entire filename is contained in %%a, all that's needed for the sourcefile is "%%a" - quoted as it will probably contain spaces.
Well - the destination directory (we've already established it with the for /f...%%b) can also contain spaces, so it needs to be quoted, too.
I've then set the flag copied to Y if the line took effect. Actually, it can be set to any non-empty value as the whole object is to interpret whether or not it exists with an if defined statement to bypass any later attempts to copy the same file (remember - copied is cleared for each file)
Now - the second option. This is actually a more powerful detector of the required target strings than is the substring version, and will detect the target string anywhere in the filename.
If you echo the name-part only of the file %%~na into a findstr, then set to findstr to look for the /L literal string /i case-insensitive c:"some literal string" and output ny matches found to nowhere (>nul) then findstr will set errorlevel to 0 if found and 1 otherwise. (the /L is superfluous here, I use it habitually to remind me I'm working with literal strings, not regular expressions)
If errorlevel n will be true if errorlevel is currently n or greater than n, so if the string is found, we do the copy and set the copied flag as before.
I reversed the order of tests because it was easier for me to do using the editor I use.
Now - there's a downside to this approach. It's a double-edged sword. Since the target string is detected wherever it appears in the filename, whatever whatever 10 something something.pdf will pass the test for 1 because Space1 appears in its name.
When the loop has finished, use timeout to wait, redirecting the output to nul to make it pipe down. Note that your delay was inside the for loop - so it would have waited 6 seconds after processing each file, not 6 seconds after processing an entire batch.
Finally, if you create terminatefilename from anothe cmd instance, the batch will exit cleanly and kill terminatefilename for you. Much cleaner than control-c.
A last note: Since you are copying the file, not MOVEing it, it will still exist in the same place presumably after the 6 seconds has elapsed and will be endlessly copied and recopied. You'd probably need to make adjustments to achieve the desired result.

Batch file to Move files based on part of filename, to folder based on part of folder name

Found a pyhton solution here, but I need a batch file-based solution.
Have many files:
SSP4325_blah-blah-blah.xml
JKP7645_blah.xml
YTG6457-blah-blah.xml
And folder names that contain a piece of the file name:
RefID - SSP4325, JKP7645, GHT1278, YRR0023
RefID - YTG6457
I'm looking for a batch solution which would read a portion of the file name at the front (before either the first dash or underscore) and then move that file into the folder where the front of the filename exists as part of the folder name.
So in the above examples, the first two files (SSP4325 and JKP7645) were moved into the first folder because it contained it contained that text as part of the folder name.
The third file would be moved into the second folder.
I have hundreds of files and 63 folders. So I'm hoping to be able to automate.
Can't use Powershell or Python due to limitations of the environment. So hoping for a batch file approach.
Thanks. Sean.

You would need to change the settings of sourcedir and destdir to suit your circumstances.
The required MOVE commands are merely ECHOed for testing purposes. After you've verified that the commands are correct, change ECHO(MOVE to MOVE to actually move the files. Append >nul to suppress report messages (eg. 1 file moved)
After establishing the directories, the outer loop puts the filename in %%a, the next loop gets the first part of that name, up to but not including the first - or _ (the delims specified) into %%b.
The inner loop finds the target directory containng %%b in the destination directory and constructs an appropriate move line.
This solution review the folders just one time and store they in an array, so this method should run faster.
#echo off
setlocal EnableDelayedExpansion
rem Process the folders
set i=0
for /D %%a in (*) do (
rem Store this folder in the next array element
set /A i+=1

for %%b in (%%a) do set "part[%%b]=!i!"

rem Get the first part of name
for /F "delims=-_" %%b in ("%%a") do (
rem If such a folder exists...
if defined part[%%b] (
rem Get the number of the corresponding array element and move the file
for %%n in (!part[%%b]!) do ECHO move "%%a" "!folder[%%n]!"
) else (
echo No folder exists for this file: "%%a"
)
)
)
This method have also several advantages: you may check if a certain folder does not exists, or get the number of files moved to each folder, etc. If you are not interested in these points, just remove the if command and make the code simpler...
An explanation of array management in Batch files is given at this answer.

Batch For loop.. wildcards to determine length of searched files?

I'm stuck on a piece of code that I mainly didn't write myself. I'm looking for a code that runs through all files with extension .dwg, and start with K_E , and have length 9. instinctively I used wildcards, but that doesn't work..
K_E??????.dwg would do the trick in my head..but doesn't.
the reason I need this length, is that in deeper folders there are
K_E??????xx.dwg and other files.
The other files in subfolders can have a range of other names, the general idea is that I only want files that are exactly named K_E[insert 6numbershere].dwg Either that, or the limit of folders depth = 2. I also tried the wildcard in the folder names to allow the code to look in only 2 deep folders for K_E*.dwg files, but that also didn't work. something like C:\Users\b00m49\Desktop\LSPTEST**\K_E*.dwg could also work..
the code is supposed to open the drawings, apply a script, and move on to the next file.
this is what I'm working with so far.
for /r "C:\Users\b00m49\Desktop\LSPTEST" %%a in (K_E*.dwg) do ( start /wait "C:\Program Files\Autodesk\Autocad 2013\acad.exe" "%%a" /b "C:\Users\b00m49\Desktop\LSPTEST\expSQM.scr")
So you just want to exclude files containing backup in their names? This should work:
#echo off
setlocal enabledelayedexpansion
for /r "C:\Users\b00m49\Desktop\LSPTEST" %%a in (K_E*.dwg) do (
set filename=%%a
if "!filename:backup=!"=="!filename!" (
rem start /wait "C:\Program Files\Autodesk\Autocad 2013\acad.exe" "%%a" /b "C:\Users\b00m49\Desktop\LSPTEST\expSQM.scr"
)
)

GOTO :EOF
You would need to change the setting of sourcedir to suit your circumstances. I used a test directory.
The required START commands are merely ECHOed for testing purposes. After you've verified that the commands are correct, change ECHO(START to START to actually start the processes.
I'm not sure what you mean by "two levels down" - I've assumed the target directory +two levels. Since your actual dirctory has 3 more levels than my test directory, you'd probably need to change 1,6 to 1,9
Simply use the tokenising feature to ensure that there are no more than ? levels of directory, where the drivename and filename count as levels. Ignore the file if there are.
Then get the name - we know the first 3 characters are K_E but we want exactly 6 characters after, so see whether there are characters 10+ and if there are not, make sure character 9 exists (characters count from 0) and if both of these conditions are valid then it must be K_E*6characters*
Could ensure that all 6 characters are numeric if required, but not actually specified.
BTW - to add information, please edit it into your question so people don't need to chase all over the thread.

This worked for me.
Notes:
The pause line should stop the procedure after it displays the command to be executed.
You would need to change U: to C: in the setting of sourcedir to have it process your c: drive.
You would need to change ECHO(start to start in order to actually execute the autocad processing. This technique (echoing the command) is used to show the command in order to have it verified. Note I've also deliberately inserted a pair of rabbit's-ears ("") because the first quoted argument to start is taken as the window-title.

Determine filename length from a batch file

I need to work two things into a .bat file I am working on for a little project. First things first, I have to know if any filename contained into the same folder (recursively) I launch my .bat in is any longer than 100 characters. If so, I need to make it 92 characters long and keep the extensions.
For example, I have this filename:
IncrediblyLongFileNameIAmSorryForThisItLooksLikeSomeDamnSpamJesusIAintEvenCloseTo100yetalmostwaitforitYEAH.omg
The above filename is 110 characters. I need to keep the extension, therefore the program should rename the file as this:
IncrediblyLongFileNameIAmSorryForThisItLooksLikeSomeDamnSpamJesusIAintEvenCloseTo100yetalmos.omg
So far, my main problem is that I don't know how to work with filename strings in batch. I used this code:
#echo off & setlocal enableextensions
FOR /R %%i IN (*.*) DO (
ECHO %%~nxi
FOR /f "delims=:" %%a in ('
^(echo."%%~nxi"^& echo.^)^|findstr /o .'
) DO set lenght=%%a-5
echo The length of "%%~nxi" is %lenght%
)
endlocal & goto :EOF
But I can't SET inside a FOR, and it can't do basic math either (i.e. it can't do the -5 operation).
The second thing, which I believe should be easier once the first one is done, is simply to compare all the filenames in the folder (recursive, once again) and make sure no filenames are the same. If the program finds any filenames that are the same, the second occurrence should be renamed to add something like l1l at the end. (I can't use parentheses here, therefore I use two ls instead to cover the number.) The only thing you need to take care of is the file extensions, because I can't add anything after the file extensions, lest they become unusable.
Can anyone offer explanations for how to accomplish this? I would really like to be able to work this out myself, but I simply lack experience in batch programming.

Reasonably simple problem.
Get a directory-list in basic form (full-filename only) and apply the full filename, name part and extension part to appropriately-named variables.
Manipulate the filename to a new name consisting of the first 92 characters of the original name part. Anticipate the need to modify this new name by establishing a modifier to optionally be applied.
See whether the proposed new name already exists in the temporary file of NEW names already processed. If not found on that file, safe to rename (if required) and record name used.
If the filename has already been used, modify it to the original first 92+ "#anumber#", increment the modifier in anticipation and try again.
Only two comments required further - first, I used # rather than ! because ! has a special meaning to batch. Second, writing :: to the tempfile (the name of the tempfile is irrelevant - I chose one that's unlikely to exist...) means that findstr doesn't complain because the file is empty, but :: can't possibly be a real filename.
The /b /e /i options to findstr mean that the name echoed in must exactly match a line (matches both /b - begin and /e - end) but /i - case is irrelevant.
