How to create a unique output filename for Windows Script? - windows

I am trying to create a windows script that should generate this kind of filename everytime I run it: filename1, filename2, filename3 and so on. Here is what I have so far:
(
#echo off
wmic logicaldisk get size,freespace,caption
) > disk.txt
I hope you can help me. Thanks!!

:: make a tempfile
:maketemp
SET "tempfile=%temp%\%random%"
IF EXIST "%tempfile%*" (GOTO maketemp) ELSE (ECHO.>"%tempfile%a")
You now have any number of filenames available.
%tempfile%a exists and is empty, but %tempfile%anythingelse should be available for use.
#ECHO OFF
SETLOCAL
SET "basename=filename"
SET /a outname=0
:genloop
SET /a outname+=1
IF EXIST "%basename% %outname%.txt" GOTO genloop
SET "outname=%basename% %outname%.txt"
ECHO %outname%
GOTO :EOF
Ah - increment the destination filename on each run. This should do that. It's not actually creating a file - you'd need to create the file %outname% each time to have it increment...
(the space between %basename% and %outname% is optional, of course - omit it if desired.)
edited to include .txt

This will give you up to 1000 filenames but you can go higher, up to 2 Billion, but the higher you go the longer the delay will be before it picks a filename.
#echo off
for /L %%a in (1,1,1000) do if not defined filename if not exist "filename%%a.txt" set "filename=filename%%a.txt"
(
wmic logicaldisk get size,freespace,caption
) > "%filename%"

#echo off
setlocal enableextensions
call :getNextFilename "filename*.txt" nextFilename
echo %nextFilename%
echo test > "%nextFilename%"
call :getNextFilename "%cd%\filename*.txt" nextFilename
echo %nextFilename%
echo test > "%nextFilename%"
endlocal
exit /b
:getNextFilename whatToSearch returnVariable
setlocal enableextensions enabledelayedexpansion
for /f %%a in ("$\%~1"
) do for /f "tokens=1,* delims=*" %%b in ("%%~nxa"
) do ( set "left=%%b" & set "right=%%c" )
set "max=0"
for %%a in ("%~1"
) do for /f "tokens=1 delims=%left%%right% " %%b in ("%%~nxa"
) do for /f "tokens=* delims=0 " %%c in ("0%%~b"
) do if %%~c geq !max! set /a "max=%%c+1"
endlocal & set "%~2=%~dp1%left%%max%%right%" & exit /b
This should find the next file in sequence independently of the existence of holes in the numeration of the files. A path can be included or omitted. The * will be used as the placeholder for the numeration. BUT this will not work if files or included paths have "problematic" characters.
If the date/time of creation of the file can be considered, then this version can be optimized as
:getNextFilename whatToSearch returnVariable
setlocal enableextensions disabledelayedexpansion
for /f %%a in ("$\%~1"
) do for /f "tokens=1,* delims=*?" %%b in ("%%~nxa"
) do ( set "left=%%b" & set "right=%%c" )
set "max=0"
for /f "delims=" %%a in ('dir /tc /o-d /b "%~1" 2^>nul'
) do for /f "tokens=1 delims=%left%%right% " %%b in ("%%~nxa"
) do for /f "tokens=* delims=0 " %%c in ("0%%~b"
) do set /a "max=%%c+1" & goto done
:done
endlocal & set "%~2=%~dp1%left%%max%%right%" & exit /b
that will take the latest created instance of the file set.

I finally figured out where to put the .txt extension. This is from #Magoo's answer but I wanted the file to be a text file so I placed the .txt twice in order for it to work properly.
#ECHO OFF
SETLOCAL
SET "basename=DISK-OUT"
SET /a outname=0
:genloop
SET /a outname+=1
IF EXIST "%basename% %outname%.txt" GOTO genloop
SET "outname=%basename% %outname%.txt"
(
wmic logicaldisk get size,freespace,caption
) > "%outname%"
GOTO :EOF

How to remove names from a list in batch

I'm using windows bath, I have a list of names that I can add to but I don't know how to remove a name from the list.
So far my code is:
#echo off
setlocal enabledelayedexpansion
set allchoices=123456789
set "names=Bob,Steven,Harry"
set amount=6 ::max limit of list
set list=0
:start
::echoes a list of all names in the list
for /l %%i in (1; 1; %amount%) do (
call :sub %%i
)
goto check
:sub
for /f "tokens=%1 delims=," %%a in ("%names%") do (
echo %%i. %%a
set /a list=list+1
)
goto :eof
:check
::Remove a name from the list
choice /c !allchoices:~0,%list%! /m "What name do you want to remove?"
if errorlevel 3 (
for /f "tokens=3 delims=," %%a in ("%names%") do (
echo you have choosen to remove %%a
::remove third name in the list
goto start
)
)
if errorlevel 2 ::remove second name in the list
if errorlevel 1 ::remove first name in the list
I've tried using del but that turns out to delete a file in your folder.
I've tried renaming a specific name using set name[%%a]="" but that did nothing.
Any ideas?
Have a look at this example. There are many ways.
#echo off
setlocal enabledelayedexpansion
set names="Bob","Steven","Harry"
for %%i in (%names%) do (
set /a num+=1
set "!num!=%%~i"
)
for /l %%a in (1,1,%num%) do (
set choices=!choices!%%a
echo !num!.!%%a!
)
choice /c 123 /m "please select name to remove"
for /l %%a in (1,1,%num%) do if not "!%%a!"=="!%errorlevel%!" set new_names=!new_names! !%%~a!
echo %new_names:~1%
It can be done without the last for loop as well.. but I opted for it.
Here is some example code, for you to run, and then try to comprehend, I hope it helps rather than confuses:
#Echo Off
SetLocal EnableDelayedExpansion
For /F "Delims==" %%A In ('Set # 2^>NUL') Do Set "%%A="
Set "i=0"
For /F "Delims=:" %%A In ('FindStr "^::" "%~f0" 2^>NUL') Do (
Set /A i+=1
Set "#!i!=%%A"
Echo= !i!. %%A
)
:Ask
Set # 1>NUL 2>&1
If ErrorLevel 1 Echo= Empty names list&Timeout 3 1>NUL&Exit /B
Echo=&Set /P "Option= Choose a name to remove>"
Set #|Findstr "^#%Option%=" 1>NUL||GoTo :Ask
Set "Name=!#%Option%!"
Echo= You've chosen to remove "%Name%"
Timeout 2 1>NUL
Set "#%Option%="

Use a Batch File to list files and allow the user to select which file to copy into a new destination

I am a newbie to Windows Scripting.
I am trying to list some txt files in several sub directories & want to copy a user selected file to a new destination. Please note that the file name is unique in different locations.
I got the first part to work (Listing out the files & locations) using the following script, but I am unable to copy the selected file to the new location.
#ECHO OFF
SET index=1
SETLOCAL ENABLEDELAYEDEXPANSION
SET FFPath="C:\Scripts - Backup Server\DKXpress_bkp"
SET NewPath=C:\DKServer
ECHO Recursively searching %FFPath%
echo.
FOR /F "delims=" %%f in ('DIR %FFPath%\*.txt /a:-d /s /b') DO (
SET file!index!=%%f
ECHO !index! - %%f
SET /A index=!index!+1
)
SETLOCAL DISABLEDELAYEDEXPANSION
SET /P selection="select file by number:"
SET file%selection% >nul 2>&1
IF ERRORLEVEL 1 (
ECHO invalid number selected
EXIT /B 1
)
SET NewFile=file%selection%
ECHO Copying %NewFile% to %NewPath%
ECHO.
COPY /Y "%NewFile%" "%NewPath%"
ECHO.
PAUSE
I think I am doing this part wrong
SET NewFile=file%selection%
Thank you all in advance
You don't need to set an index variable or delayed expansion, if you let Find do the work for you:
#Echo Off
Set "FFPath=C:\Scripts - Backup Server\DKXpress_bkp"
Set "NewPath=C:\DKServer"
Echo Recursively searching %FFPath%
Echo=
For /F "Delims==" %%A In ('"Set File[ 2>Nul"') Do Set "%%A="
For /F "Tokens=1* Delims=]" %%A In (
'"Dir /B/S/A-D-S-L "%FFPath%\*.txt" 2>Nul|Find /N /V """') Do (
Echo %%A] %%B
Set "File%%A]=%%B"
)
Echo=
Set /P "#=Select file by number: "
Echo=
For /F "Tokens=1* Delims==" %%A In ('"Set File[%#%] 2>Nul"') Do (
Echo Copying %%B to %NewPath%&Echo=
Copy /Y "%%B" "%NewPath%"
GoTo :End
)
Echo Invalid number selected
:End
Echo=
Pause
You need to use delayed expansion to get the file name assigned to the variable correctly.
SET NewFile=!file%selection%!
Remove the setlocal to disable delayed expansion.
You can try something like that :
#ECHO OFF
:Main
cls
SET index=1
SETLOCAL ENABLEDELAYEDEXPANSION
SET FFPath="C:\Scripts - Backup Server\DKXpress_bkp"
SET "NewPath=C:\DKServer"
ECHO Recursively searching %FFPath%
echo.
FOR /F "delims=" %%f in ('DIR %FFPath%\*.txt /a:-d /s /b') DO (
SET filepath[!index!]=%%f
ECHO [!index!] - %%~nxf - %%f
SET /A index=!index!+1
)
echo(
echo select file by number :
set /p Input=""
For /L %%i in (1,1,%index%) Do (
If "%INPUT%" EQU "%%i" (
ECHO Copying "!filepath[%%i]!" to "!NewPath!"
COPY /Y "!filepath[%%i]!" "!NewPath!"
)
)
echo Copying another file ? (Y = Yes or N = No) ?
set /p input2=""
If /I "!input2!"=="Y" (
goto :Main
) else (
goto :eof
)

Output filename and count of a directory in a text file - windows

I have a batch to output filename and count of filenames with the same prefix and date in a text file.
E.g.
Q1231111.zip
Q1241111.zip
where:
Q123 - is a prefix
1111 - is a date.
I want an output such as:
123 : 1
124 : 1
125 : 0
But the batch file unable to output the last one. I wanna see the file is present so i need the 0 output.
Here's my code:
#echo off
setlocal EnableExtensions
for %%I in ("Z:\StoreDataJDA\Q1231111.zip") do call :CountFile "%%~nI"
for %%I in ("Z:\StoreDataJDA\Q1241111.zip") do call :CountFile "%%~nI"
for %%I in ("Z:\StoreDataJDA\Q1251111.zip") do call :CountFile "%%~nI"
for /F "tokens=2,3 delims=#=" %%I in ('set Group# 2^>nul') do echo %%I: %%J >>count.txt
endlocal
goto :EOF
:CountFile
set "FileName=%~1"
set "FileGroup=%FileName:~1,4%"
if "Group#%FileGroup%" == "" (
set "Group#%FileGroup%=1"
) else (
set /A Group#%FileGroup%+=1
)
goto :EOF
pause
Thanks in advance!
From your description, it's hard to tell exactly what you are looking for. But by looking at your very similar question from a year ago, and from Gerhard's comment, I think what you're looking for is:
Count the number of files with a given prefix, each file having a different date suffix.
I think this should do it:
#echo off
setlocal EnableExtensions
set "Group#123=0" & for %%I in ("Z:\StoreDataJDA\Q123????.zip") do call :CountFile "%%~nI"
set "Group#124=0" & for %%I in ("Z:\StoreDataJDA\Q124????.zip") do call :CountFile "%%~nI"
set "Group#125=0" & for %%I in ("Z:\StoreDataJDA\Q125????.zip") do call :CountFile "%%~nI"
(for /F "tokens=2,3 delims=#=" %%I in ('set Group# 2^>nul') do echo %%I: %%J)>count.txt
endlocal
goto :EOF
:CountFile
set "FileName=%~1"
set "FileGroup=%FileName:~1,3%"
set /A Group#%FileGroup%+=1
goto :EOF

Batch split a text file

I have this batch file to split a txt file:
#echo off
for /f "tokens=1*delims=:" %%a in ('findstr /n "^" "PASSWORD.txt"') do for /f "delims=~" %%c in ("%%~b") do >"text%%a.txt" echo(%%c
pause
It works but it splits it line by line. How do i make it split it every 5000 lines. Thanks in advance.
Edit:
I have just tried this:
#echo off
setlocal ENABLEDELAYEDEXPANSION
REM Edit this value to change the name of the file that needs splitting. Include the extension.
SET BFN=passwordAll.txt
REM Edit this value to change the number of lines per file.
SET LPF=50000
REM Edit this value to change the name of each short file. It will be followed by a number indicating where it is in the list.
SET SFN=SplitFile
REM Do not change beyond this line.
SET SFX=%BFN:~-3%
SET /A LineNum=0
SET /A FileNum=1
For /F "delims==" %%l in (%BFN%) Do (
SET /A LineNum+=1
echo %%l >> %SFN%!FileNum!.%SFX%
if !LineNum! EQU !LPF! (
SET /A LineNum=0
SET /A FileNum+=1
)
)
endlocal
Pause
exit
But i get an error saying: Not enough storage is available to process this command
This will give you the a basic skeleton. Adapt as needed
#echo off
setlocal enableextensions disabledelayedexpansion
set "nLines=5000"
set "line=0"
for /f "usebackq delims=" %%a in ("passwords.txt") do (
set /a "file=line/%nLines%", "line+=1"
setlocal enabledelayedexpansion
for %%b in (!file!) do (
endlocal
>>"passwords_%%b.txt" echo(%%a
)
)
endlocal
EDITED
As the comments indicated, a 4.3GB file is hard to manage. for /f needs to load the full file into memory, and the buffer needed is twice this size as the file is converted to unicode in memory.
This is a fully ad hoc solution. I've not tested it over a file that high, but at least in theory it should work (unless 5000 lines needs a lot of memory, it depends of the line length)
AND, with such a file it will be SLOW
#echo off
setlocal enableextensions disabledelayedexpansion
set "line=0"
set "tempFile=%temp%\passwords.tmp"
findstr /n "^" passwords.txt > "%tempFile%"
for /f %%a in ('type passwords.txt ^| find /c /v "" ') do set /a "nFiles=%%a/5000"
for /l %%a in (0 1 %nFiles%) do (
set /a "e1=%%a*5", "e2=e1+1", "e3=e2+1", "e4=e3+1", "e5=e4+1"
setlocal enabledelayedexpansion
if %%a equ 0 (
set "e=/c:"[1-9]:" /c:"[1-9][0-9]:" /c:"[1-9][0-9][0-9]:" /c:"!e2![0-9][0-9][0-9]:" /c:"!e3![0-9][0-9][0-9]:" /c:"!e4![0-9][0-9][0-9]:" /c:"!e5![0-9][0-9][0-9]:" "
) else (
set "e=/c:"!e1![0-9][0-9][0-9]:" /c:"!e2![0-9][0-9][0-9]:" /c:"!e3![0-9][0-9][0-9]:" /c:"!e4![0-9][0-9][0-9]:" /c:"!e5![0-9][0-9][0-9]:" "
)
for /f "delims=" %%e in ("!e!") do (
endlocal & (for /f "tokens=1,* delims=:" %%b in ('findstr /r /b %%e "%tempFile%"') do #echo(%%c)>passwords_%%a.txt
)
)
del "%tempFile%" >nul 2>nul
endlocal
EDITED, again: Previous code will not correctly work for lines starting with a colon, as it has been used as a delimiter in the for command to separate line numbers from data.
For an alternative, still pure batch but still SLOW
#echo off
setlocal enableextensions disabledelayedexpansion
set "nLines=5000"
set "line=0"
for /f %%a in ('type passwords.txt^|find /c /v ""') do set "fileLines=%%a"
< "passwords.txt" (for /l %%a in (1 1 %fileLines%) do (
set /p "data="
set /a "file=line/%nLines%", "line+=1"
setlocal enabledelayedexpansion
>>"passwords_!file!.txt" echo(!data!
endlocal
))
endlocal
Test this: the input file is "file.txt" and output files are "splitfile-5000.txt" for example.
This uses a helper batch file called findrepl.bat - download from: https://www.dropbox.com/s/rfdldmcb6vwi9xc/findrepl.bat
Place findrepl.bat in the same folder as the batch file or on the path.
#echo off
:: splits file.txt into 5000 line chunks.
set chunks=5000
set /a s=1-chunks
:loop
set /a s=s+chunks
set /a e=s+chunks-1
echo %s% to %e%
call findrepl /o:%s%:%e% <"file.txt" >"splitfile-%e%.txt"
for %%b in ("splitfile-%e%.txt") do (if %%~zb EQU 0 del "splitfile-%e%.txt" & goto :done)
goto :loop
:done
pause
A limitation is the number of lines in the file and the real largest number is 2^31 - 1 where batch math tops out.
#echo off
setlocal EnableDelayedExpansion
findstr /N "^" PASSWORD.txt > temp.txt
set part=0
call :splitFile < temp.txt
del temp.txt
goto :EOF
:splitFile
set /A part+=1
(for /L %%i in (1,1,5000) do (
set "line="
set /P line=
if defined line echo(!line:*:=!
)) > text%part%.txt
if defined line goto splitFile
exit /B
If the input file has not empty lines, previous method may be modified in order to run faster.

My idea is to to do the filetring through the :concat subroutine, problem is set is_env_to_exclude=yes insrtuction inside the for loop isn't working, when i execute the script the echo flag is displaying but the set is_env_to_exclude is always set to no.
I think what you need is to break the loop:
echo the environment is %1
set is_env_to_exclude=no
for %%L in (%env_to_exclude%) do (
set is_env_to_exclude=no
for /f "usebackq delims=" %%U in (`echo %1 ^| findstr %%L`) do (
set is_env_to_exclude=yes
echo flag du Ellouze
goto :break_loop
)
)
:break_loop
echo %is_env_to_exclude%
as on each iteration over %env_to_exclude% items the is_env_to_exclude is set to no.
Although the code is a little bit complicated for me :)
It really depends on the contents of env_to_exclude.
is_env_to_exclude will be set to no for each %%L, so even if it is set to yes once, if there are more elements processed after it's been set, it will be re-set to no.
The
set is_env_to_exclude=no
in the loop seems to be the culprit; removing it would seem to fix the problem.
AAMOI, set "flag=" and set flag=Y allows if [not] defined flag which has the added advantage that the CURRENT status of the flag is available within a FOR loop without needing enabledelayedexpansion.
