CMD: extract part of a filename and use it as variable - variables

I ripped my CDs with EAC to CUE+WAV files, added cover art and all my files are in the same folder with filenames pattern "Album artist - Album title", for ex.:
Clannad - Legend.wav/cue/jpg
David Bowie - Best Of Bowie [Disc 1].wav/cue/jpg
David Bowie - Best Of Bowie [Disc 2].wav/cue/jpg
I'm new to this so I wrote a simple CMD batch to convert my music to FLAC format, but it requires manual copying and pasting of the actual wav/cue/jpg filenames and input of album artist, disc no. and total disc no. for their corresponding tags. It cannot be stored in cuesheet file for some reason, but in my case I have them in filenames as you can see above).
ECHO WAV/CUE/JPG FILENAME
SET /P "input="
ECHO ALBUMARTIST
SET /P "albumartist="
ECHO DISCNUMBER
SET /P "discnumber="
ECHO TOTALDISCS
SET /P "totaldiscs="
flac.exe -0 --picture="D:\Music\%input%.jpg" --tag-from-file="CUESHEET=D:\Music\%input%.cue" -T "ALBUMARTIST=%albumartist%" -T "DISCNUMBER=%discnumber%" -T "TOTALDISCS=%totaldiscs%" "D:\Music\%input%.wav"
My question is about automation of converting all my ripped albums. How can I extract album artist/disc no./total disc no. info from filenames and loop that for every .wav file?

#ECHO OFF
SETLOCAL

GOTO :eof
You would need to change the setting of destdir to suit your circumstances.
The above will merely echo the required flac line. I left it as you posted but set the scant test data you posted up as I interpret it (ie. there is a set of 3 files) on my U: drive.
Sadly, you've given us insufficient information. I've assumed that you need all three files to be present, and the default for totaldiscs is 1.
First, look for all .jpgs, and if there is a corresponding .wav and .cue then process for flac generation as follows:
Set input to the name part of the .jpg found
set albumartist to the first part of the filename, up to the -
get the [disc n] string if it's present
count the number of .wavs that start with the filename up to the [
generate the flac line.
Within the generation of the flac line, we strip off the trailing spaces from input, convert disc n to n or set disc to 1 (although this information may not be needed), and set the totaldiscs to 1 if it's not been calculated.
You don't say what flac produces as output, but I'd suggest that you further gate that filetype so that the procedure doesn't run if the %input%.finalproductwhateverthatis file is present.

This is very similar to Magoo's answer, with some bug fixes, and everything is done in one master loop without a CALL. As with Magoo's answer, modify your destination folder at the beginning to suit your needs.
#echo off
:: Delayed expansion must be disabled to protect ! when expanding FOR variables.
:: It is normally disabled by default, but I'm making it explicit, just to be sure.
setlocal disableDelayedExpansion

:: Define where output should be stored
set "destination=D:\Music"
pushd "%destination%"
:: Iterate each .wav file (A) and only proceed if .jpg and .cue also exists
for /f "delims=" %%A in ('dir /b /a-d "%source%\*.wav"') do if exist "%source%\%%~nA.jpg" if exist "%source%\%%~nA.cue" (

)

You may want to add a check to only proceed if the FLAC file does not already exist so you can run the script multiple times without reprocessing files. The outer loop would look something like this, but I can't be sure since I don't know the format of the output file name:
for /f "delims=" %%A in ('dir /b /a-d "%source%\*.wav"') do if exist "%source%\%%~nA.jpg" if exist "%source%\%%~nA.cue" if not exist "%destination%\%%~nA.flac" (
The logic is much simpler using my JREPL.BAT utility if you understand regular expressions:
#echo off
:: Delayed expansion must be disabled to protect ! when expanding FOR variables.
:: It is normally disabled by default, but I'm making it explicit, just to be sure.
setlocal disableDelayedExpansion
:: Define where source files are coming from
set "source=D:\music"
:: Define where output should be stored
set "destination=D:\music"
pushd "%destination%"
:: Iterate all *.wav and use JREPL to format result as "fullFileName|artist - album|artist|Disc#"
:: %%A %%B %%C %%D
:: Only proceed if .jpg and .cue also exist
for /f "tokens=1-4 delims=|" %%A in (
'dir /b /a-d "%source%\*.wav"^|jrepl "^((.+?) - .+?)(?:\[Disc (\d+)])?\.wav$" "$&|$1|$2|$3" /i'
) do if exist "%%~nA.jpg" if exist "%%~nA.cue" (
%= disc and count are both 1 if %%D is empty =%
if "%%D" equ "" (
flac.exe -0 --picture="%source%\%%~nA.jpg" --tag-from-file="CUESHEET=%source%\%%~nA.cue" -T "ALBUMARTIST=%%C" -T "DISCNUMBER=1" -T "TOTALDISCS=1" "%source%\%%A"
%= else count the number of .wav files =%
) else for /f %%E in ('dir /b /a-d "%%B[*.wav"^|find /c /v ""') do (
flac.exe -0 --picture="%source%\%%~nA.jpg" --tag-from-file="CUESHEET=%source%\%%~nA.cue" -T "ALBUMARTIST=%%C" -T "DISCNUMBER=%%D" -T "TOTALDISCS=%%E" "%source%\%%A"
)
)
popd
Again, you can add an IF to the outer loop to proceed only if the .flac file does not already exist in the destination.

How can the results of a pipeline be captured in a batch var without temp file?

Trying to get the number of disks in a system using diskpart without using a temp file. This works on the command line:
echo list disk | diskpart | find /C "Disk"
but I can't figure out how to redirect the result into a batch var. Of course the number printed by the above pipeline is higher due to labels, but they are constant (divide result by 3 for actual number of disks).
Any ideas?
I've tried:
set /A disks=<echo list disk...
set /A disks<echo list disk...
set /A disks= (echo list disk ...)
You need FOR F for capture the output of a program.
set "cmd=echo list disk | diskpart | find /C "Disk""
setlocal EnableDelayedExpansion
FOR /F "usebackq delims=" %%A in (`!cmd!`) do (
set var=%%A
)
echo !var!
You can do it with a batch file using WMIC like this:
#echo off
wmic logicaldisk get caption,providername,drivetype,volumename > ListDisk.txt
Start "" ListDisk.txt
pause
And if you want to echo the fixed drive like that :
#echo off
for /f "tokens=2" %%i in ('wmic logicaldisk where "drivetype=3" ^|find /i ":"') do (Set FixedDrive=%%i)
echo %FixedDrive%
pause

FINDSTR in FOR loop with variables as strings (Batch File)

It's my first post here, unfotrtunately question to you instead of help.
I'm writing small program which moves text and pdf files when string is found in text file.(1.txt, 1.txt.pdf ...) It was working very good when i had variables manually set in batch like this :
set c1=xxx
set p1=c:\test\xxx\
set c2=yyy
set p2=c:\test\yyy\
FOR /f "tokens=*" %%A IN ('FINDSTR /i /m "%c1%" "c:\test\*.txt"') DO (
IF "%ERRORLEVEL%"=="0" MOVE %%A "%p1%">nul
MOVE %%A.pdf %p1%
FOR /f "tokens=*" %%A IN ('FINDSTR /i /m "%c2%" "c:\test\*.txt"') DO (
IF "%ERRORLEVEL%"=="0" MOVE %%A "%p2%">nul
MOVE %%A.pdf %p2%
Now I'm trying to use input file with variables :
for /F "delims=^ tokens=1,2" %%A in (c:\test\db\input.cdb) do (
SET /A vidx=!vidx! + 1
set c!vidx!=%%A & set p!vidx!=%%B
It works good, but the problem starts when I try to use for loop for all this variables. Literally search for all (c1,c2,c3...) variables and move them to (p1,p2,p3,...) paths.
Input.cdb looks like this :
xxx ^ c:\test\xxx
yyy ^ c:\test\yyy
Code:
setlocal ENABLEDELAYEDEXPANSION
set vidx=0
for /F "delims=^ tokens=1,2" %%A in (c:\test\db\input.cdb) do (
SET /A vidx=!vidx! + 1
set c!vidx!=%%A & set p!vidx!=%%B
FOR /f "tokens=*" %%D IN ('FINDSTR /i /m "%c!vidx!%" "c:\test\*.txt"') DO (
IF "%ERRORLEVEL%"=="0" MOVE %%D "%p!vidx!%">nul
MOVE "%%D.pdf" "%p!vidx!%"
ECHO %%D File is being procesed now
)
)
I don't know why this code doesn't work, maybe because there is loop inside loop?
Or how to create loop to do the same from 0 to how many lines of variables has been read from input.cdb?
I've tried to run this in separate for loop with temporary variable but it's still not using my string and path variables.
Thank you in advance for any help!
With Regards

Ugh. More than one problem, and what is the appropriate solution?
First item is a matter of logical design. Let's assume that the batch worked as intended. c!vidx! would be set to %%A and p!vidx! to %%B, so unless there's some unpublished use for c... and p... then you could simply substitute as follows:
setlocal ENABLEDELAYEDEXPANSION
for /F "delims=^ tokens=1,2" %%A in (c:\test\db\input.cdb) do (
FOR /f "tokens=*" %%D IN ('FINDSTR /i /m "%%A" "c:\test\*.txt"') DO (
IF "%ERRORLEVEL%"=="0" MOVE %%D "%%B">nul
MOVE "%%D.pdf" "%%B"
ECHO %%D File is being procesed now
)
)
Now - there's a common fundamental misconception about %var% where var is any variable (including %ERRORLEVEL% and %C!vidx!%...) - a %VAR% occurring in a compound statement (or "block") - within the parentheses if a FOR...DO (in here) or IF...(here) ELSE (or here) is replaced with that variable's value at the time the outermost statement is parsed - before it is executed. If delayedexpansion is invoked (as you have) then !var! refers to the run-time value and %var% to the parse-time value.
Hence, if "%errorlevel%"=="0" would be evaluated according to the state of errorlevel when the for...%%A was parsed, not the value as set by the findstr.
This can be corrected by
setlocal ENABLEDELAYEDEXPANSION
for /F "delims=^ tokens=1,2" %%A in (c:\test\db\input.cdb) do (
FOR /f "tokens=*" %%D IN ('FINDSTR /i /m "%%A" "c:\test\*.txt"') DO (
IF not errorlevel 1 MOVE %%D "%%B">nul
MOVE "%%D.pdf" "%%B"
ECHO %%D File is being procesed now
)
)
Where IF not errorlevel 1 is interpreted as if the CURRENT (run-time) errorlevel is NOT (1 or greater than 1)

Batch failure set value to a variable

this is my code:
#echo off
Setlocal EnableDelayedExpansion
set log=C:\mylog.log
set ftpFolder=C:\contributor\ftp
set rotterdamFolder=C:\rotterdam
cd /D C:\contributor
echo [FTP Folder: %ftpFolder%] >> %log%
cd /D %ftpFolder%
for /D %%f in (*) do (
cd %%f
for %%i in (*) do (
echo [FTP, %%f] Sending %%i >> %log%
for /f "tokens=1,2" %%a in (C:\input.txt) do (
if %%a==%%f (
set et=%%b
)
)
copy %ftpFolder%\%%f\%%i %rotterdamFolder%\%et% >> %log%
)
cd .. >> %log%
)
input.txt file is something like:
007 87855
008 87823
015 87830
it's not important how the two columns are divided (tab or space).
my problem is that %et% variable is not defined. how is it possible? I need to use variable "b" as destination folder. where is the error?
%et% is expanded when the line is parsed, and the entire outer parenthesized FOR loop is parsed all at once. So the value you get is the value that existed before your loop was entered.
You could solve the problem by enabling delayed expansion and using !et! instead. Type HELP FOR or FOR /? from the command line for more information. The section about delayed expansion is about halfway down.
But there really isn't any need to use the et variable at all. I believe you only want to copy the file when the first column of the inner loop matches the folder name. Simply move and substitute the COPY command for the SET statement. Use %%b instead of %et% in the COPY statement.
It wasn't necessary, but I substituted PUSHD/POPD for the CD commands. The redirection with CD is pointless when a path is specified.
You really should quote your paths in case they contain spaces or special characters.
for /D %%f in (*) do (
pushd "%%f"
for %%i in (*) do (
echo [FTP, %%f] Sending %%i >> %log%
for /f "tokens=1,2" %%a in (C:\input.txt) do if "%%a"=="%%f" (
copy "%ftpFolder%\%%f\%%i" "%rotterdamFolder%\%%b" >> %log%
)
)
popd
)

Findstr, how to read part of string/line

I have file with a list of names and extensions, formatted such as below each on it's own line:
JoeBloggs=102
JohnSmith=109
What I want to do is use findstr but read the number after the equals sign. So I am using the following command:
#echo off
for /F "delims=" %%a in ('findstr /p %username% extensions.txt') do set ext=%%a
If a user logs on as JoeBloggs it will capture JoeBloggs=102, what I want it to do is only capture 102. So essentially only the numbers after the equals sign.
#echo off
for /f "tokens=1,2 delims==" %%a in (names.txt) do (
if "%%a"=="%username%" set ext=%%b
)
echo %ext%
pause >nul
This will read each line of your text file and split it when it comes across an = sign.
I have specified to use tokens 1 and 2, 1 being before the split, and 2 being after so we can compare the first and if it's what you want, use the second.

How to delete a line of a text file, given the line number using batch (.bat) script?

I want to write a batch script where the user can enter the line number and the script will delete that line of a text file.
Eg: tmp.txt
1. aaa
2. bbb
3. ccc
4. ddd
I want when i execute my script and user inputs 3, the tmp.txt to be
1. aaa
2. bbb
4. ddd
I am trying something like this:
#ECHO OFF
SET /P LINENUMBER=Enter the Line No:
FOR /F "tokens=1* delims=[]" %%a IN ('FIND /n /v "" ^< tmp.txt') DO (
IF %%a equ %LINENUMBER% (
????????????????????
)
)
You cannot modify the file directly. You must create a new file with the desired content and then replace the original file with the new file.
You create the new file by redirecting output and ECHOing the desired content. I use ECHO(%%b in case %%b is empty because the line was blank. ECHO %%b would produce ECHO is off. if b is empty. Most people use ECHO., but that can fail under esoteric conditions. ECHO( will never fail.
You use MOVE to replace the original file with the new.
You can eliminate the need to check for the number within your FOR /F loop by using FINDSTR after FIND to filter out the unwanted line.
Note that your code, as written so far, will strip any leading [ and ] characters from each line. Because the line filter is applied before the FOR iteration, you can improve the situation slightly by setting DELIMS to ] only.
#ECHO OFF
SET /P LINENUMBER=Enter the Line No:
>tmp.txt.new (
FOR /F "tokens=1* delims=]" %%a IN (
'FIND /n /v "" ^<tmp.txt^|FINDSTR /VLB "[%LINENUMBER%]"'
) DO ECHO(%%b
)
>nul MOVE /y tmp.txt.new tmp.txt
If any of your original lines already begin with ] then you can use FINDSTR instead of FIND to introduce the line number. That uses nn: format instead of [nn]. This solution will strip leading : from your lines.
#ECHO OFF
SET /P LINENUMBER=Enter the Line No:
>tmp.txt.new (
FOR /F "tokens=1* delims=:" %%a IN (
'FINDSTR /n "^" tmp.txt^|FINDSTR /VLB "%LINENUMBER%:"'
) DO ECHO(%%b
)
>nul MOVE /y tmp.txt.new tmp.txt
If your text file contains lines that begin both with : and ] then you can't use FOR /F to parse out the line number. Instead you use search and replace. Delayed expansion is toggled on and off within the loop to protect any ! that may exist in the file.
#ECHO OFF
setlocal disableDelayedExpansion
SET /P LINENUMBER=Enter the Line No:
>tmp.txt.new (
FOR /F "delims=" %%a IN (
'FINDSTR /n "^" tmp.txt ^| FINDSTR /VLB "%LINENUMBER%:"'
) DO (
set "ln=%%a"
setlocal enableDelayedExpansion
echo(!ln:*:=!
endlocal
)
)
>nul MOVE /y tmp.txt.new tmp.txt
try out this:
#echo off & setlocal
set "InFile=Z:\Text.txt"
set "OutFile=Z:\Erg.txt"
set /p LineToDelete=
if exist "%OutFile%" del "%OutFile%"
for /f "tokens=1* delims=:" %%i in ('findstr /n $ "%InFile%"^|findstr /b "%LineToDelete%:"') do findstr /v /b /c:"%%j" "%InFile%">>"%OutFile%"
