My question is: How to set %%b and %%d as a1 and a2? How can I do this? Is it possible ? Please answer my question as fast as it possible. The text file contains that:
radek ma 29 lat jarek ma 35 lat

As soon as possible? Pay a little of your time to learning, start with results of next code snippet.
#ECHO OFF >NUL

How can I read the last 2 lines of a file in batch script

I have a Java program that appends new builds information in the last two lines of a file.
How can I read them in batch file?
This code segment do the trick...
for /F "delims=" %%a in (someFile.txt) do (
set "lastButOne=!lastLine!"
set "lastLine=%%a"
)
echo %lastButOne%
echo %lastLine%
EDIT: Complete TAIL.BAT added
This method may be modified in order to get a larger number of lines, that may be specified by a parameter. The file below is tail.bat:
#echo off
setlocal EnableDelayedExpansion
rem Tail command in pure Batch: Tail.bat filename numOfLines
rem Antonio Perez Ayala
for /F "delims=" %%a in (%1) do (
set /A i=%2, j=%2-1
for /L %%j in (!j!,-1,1) do (
set "lastLine[!i!]=!lastLine[%%j]!
set /A i-=1
)
set "lastLine[1]=%%a"
)
for /L %%i in (%2,-1,1) do if defined lastLine[%%i] echo !lastLine[%%i]!
2ND EDIT: New version of TAIL.BAT added
The version below is more efficient:
#echo off
setlocal EnableDelayedExpansion
rem Tail command in pure Batch, version 2: Tail.bat filename numOfLines
rem Antonio Perez Ayala
set /A firstTail=1, lastTail=0
for /F "delims=" %%a in (%1) do (
set /A lastTail+=1, lines=lastTail-firstTail+1
set "lastLine[!lastTail!]=%%a"
if !lines! gtr %2 (
set "lastLine[!firstTail!]="
set /A firstTail+=1
)
)
for /L %%i in (%firstTail%,1,%lastTail%) do echo !lastLine[%%i]!
This will solve the problem, where someFile.txt is the file where you want to read the lines from:
for /f %%i in ('find /v /c "" ^< someFile.txt') do set /a lines=%%i
echo %lines%
set /a startLine=%lines% - 2
more /e +%startLine% someFile.txt > temp.txt
set vidx=0
for /F "tokens=*" %%A in (temp.txt) do (
SET /A vidx=!vidx! + 1
set localVar!vidx!=%%A
)
echo %localVar1%
echo %localVar2%
del temp.txt
::change the values bellow with a relevant ones.
set "file=C:\some.file"
set "last_lines=2"
for /f %%a in ('findstr /R /N "^" "%file%" ^| find /C ":"') do #set lines=%%a
set /a m=lines-last_line
more +%m% "%file%"
Directly from the command line:
C:\>set "file=C:\some.file"
C:\>set "last_lines=5"
C:\>(for /f %a in ('findstr /R /N "^" "%file%" ^| find /C ":"') do #set lines=%a)&#set /a m=lines-last_lines&call more +%m% "%file%"

select file with the largest number of lines

It count number of line in all file but i need select the file with the largest number of lines.
for %%a in (*.*) do (
for /f %%b in (' find "" /v /c ^< "%%a" ') do (
echo %%a=%%b
)
)
Output:
test.txt=10
asdasd.txt=15
asdasd.txt=20
I need output:
asdasd.txt=20
only one file with the largest number of lines
Pleas help. Thx
First option, calling find for each file and then parsing output
#echo off
setlocal enableextensions enabledelayedexpansion
set "maxLines=0"
set "maxFile="
for %%a in (*.txt) do (
for /f %%b in ('^<"%%a" find /c /v ""') do if %%b gtr !maxLines! (
set "maxLines=%%b"
set "maxFile=%%a"
)
)
echo %maxFile%=%maxLines%
Second option, calling find only one time and parsing output
#echo off
setlocal enableextensions enabledelayedexpansion
set "maxLines=0"
set "maxFile="
for /f "tokens=* delims=- " %%a in ('find /c /v "" *.txt '
) do for /f "tokens=1,2 delims=:" %%b in ("%%a"
) do if %%c gtr !maxLines! (
for %%d in (%%c) do set "maxLines=%%d"
set "maxFile=%%b"
)
echo %maxFile%=%maxLines%
you need to set additional vars:
echo off
setlocal enableextensions enabledelayedexpansion
set /A counter=0
for /f "tokens=1,2* delims=-:" %%a in ('find /c /v "" *.*') do (
if !counter! LSS %%b (
set /A counter=%%b
set bezieher=%%~nxa)
)
)
echo %bezieher%=%counter%
pause

Create List of file for a directory

I have a directory of files for example:
\1.gif
\1.pdf
\1.doc
\2.gif
\2.pdf
\2.doc
\3.gif
\4.gif
How do I get a file with just the list of files (with extensions) that have unique filenames? (i.e. 3.gif, 4.gif)
Thanks
This does not work with special characters like !, = and more.
#ECHO OFF &SETLOCAL
for %%a in (*) do set ".%%~na=%%~xa"& set /a $%%~na+=1
for /f "tokens=1*delims==." %%a in ('set .') do for /f "tokens=2delims==" %%c in ('set "$%%a"') do if %%c==1 echo(%%a.%%b
i havent tested it, but try this:
#echo off
setlocal enabledelayedexpansion
pushd path\to\dir
for /f %%i in ('dir /b *.gif') do (
find "%%~ni" "%tmp%\u" >nul 2>&1 || echo %%~ni >> "%tmp%\u"
)
for /f %%i in ('type "%tmp%\u"') do (
set inc=
for /f %%j in ('dir %%i.gif /b') do set /a inc+=1
if !inc! EQU 1 (dir /b %%i.* ^|find "log" /v >> log)
)
please feel free to comment if there are any mistakes, not in a position to test it right now.
This will work as long as none of the file names contain the = character:
#echo off
setlocal
for /f "eol== delims==" %%V in ('"set _ 2>nul"') do set "%%V="
for %%F in (*) do if not defined _%%~nF (set "_%%~nF=%%F") else set "_%%~nF=="
for /f "eol== tokens=2 delims==" %%F in ('"set _|findstr /v =="') do #echo %%F
EDIT
If you want to restrict output to only one file type, .gif for example, then all you need is an extra FINDSTR:
#echo off
setlocal
for /f "eol== delims==" %%V in ('"set _ 2>nul"') do set "%%V="
for %%F in (*) do if not defined _%%~nF (set "_%%~nF=%%F") else set "_%%~nF=="
for /f "eol== tokens=2 delims==" %%F in ('"set _|findstr /v ==|findstr /lie .gif"') do #echo %%F

Loop through list, set variable

I'm trying to make a loop that goes through a file with filenames on each line, set the first filename as a variable and execute the rest if the script. Then take the second line and do the same.
etc. etc.
The problem is that it only does the first line of filenames.txt
#echo off
for /F "tokens=*" %%G in (filenames.txt) do (
set filename=%%G
script
script
script
)
pause
It has be a batch file.
The whole script:
#ECHO OFF
for /F "tokens=*" %%G in (filenames.txt) do (
SET FileName=%%G
SET Word1="ts_confirmImplicitSAMM.gram"
SET Word2="SWIrcnd"
for /f "tokens=3" %%f in ('find /c /i %Word1% %FileName%') do set PairsToShow=%%f
SET /a Lines1=0, Lines2=0
FOR /f "delims=" %%a IN ('findstr "%Word1%" "%FileName%"') DO (
SET "str=%%a"
SET /a Lines1+=1
SETLOCAL enabledelayedexpansion
SET "$1!Lines1!=!str!"
FOR /f "tokens=1*delims==" %%b IN ('set "$1"') DO (IF "!"=="" endlocal)&SET "%%b=%%c"
)
FOR /f "delims=" %%a IN ('findstr "%Word2%" "%FileName%"') DO (
SET "str=%%a"
SET /a Lines2+=1
SETLOCAL enabledelayedexpansion
SET "$2!Lines2!=!str!"
FOR /f "tokens=1*delims==" %%b IN ('set "$2"') DO (IF "!"=="" endlocal)&SET "%%b=%%c"
)
SET /a Lines=Lines1+Lines2
ECHO(%Lines% lines read from %FileName%.
IF %Lines1% leq %Lines2% (SET /a MaxPairs=Lines1) ELSE SET /a MaxPairs=Lines2
IF %PairsToShow% gtr %MaxPairs% (
ECHO only text for %MaxPairs% pairs NOT %PairsToShow% :/
GOTO :END
)
(FOR /l %%a IN (1,1,%PairsToShow%) DO (
SETLOCAL ENABLEDELAYEDEXPANSION
CALL SET "Line1=%%$1%%a%%"
CALL SET "Line2=%%$2%%a%%"
<NUL SET /p "=!Line1!"
ECHO !Line2!
ENDLOCAL
))>> result1.txt
ENDLOCAL
TYPE result1.txt| FINDSTR /V EVNT=SWIgrld >> result.txt
DEL result1.txt
PAUSE
)
Without seeing the rest of your script... you probably need to do 1 of 2 things:
Use SETLOCAL ENABLEDELAYEDEXPANSION (as 2nd line of your script) and then reference the variable filename as !filename! instead of %filename% to use the run-time value instead of the load-time value. But that could cause other problems, depending on what goes on in "script".
Just use %%G instead of filename

Order files list by batch

I have a long list of individual songs not in folders just songs, and I'd like to move them to the folder of theire artist. the songs are in the following format
artist - songname.flac
I can store them in a list, and echo it, but splitting the artist and songname in 2 vars, I can't seem to figure out.
Could someone help me with the splitting (or if you want even with the rest of the script)
this is what I have so far:
#echo off
setlocal enabledelayedexpansion
set N=0
for %%i in (*) do (
set Files[!N!]=%%~ni
set /a N+=1
)
for /l %%x in (1,1,%N%) do echo.!Files[%%x]!
pause
set SOURCE=c:\temp\test
for /f "delims=-. tokens=1,2" %%i in ('dir /b "%SOURCE%\*.flac"') do echo Artist : %%i Song : %%j
update for full script (got to check if it works with space and special chars in path) :
#echo off
setlocal enabledelayedexpansion
set SOURCE=c:\temp\test
set DESTINATION=c:\temp\test
for /f "tokens=*" %%i in ('dir /b "%SOURCE%\*.flac"') do call :OrderThatMess "%%i"
:OrderThatMess
set NAME=%1
for /f "tokens=1,2 delims=-. " %%j in (%1) do (
set ARTIST=%%j
set TITLE=%%k
if not exist "%DESTINATION%\%ARTIST%" (md "%DESTINATION%\%ARTIST%" )
copy %SOURCE%\%NAME% "%DESTINATION%\%ARTIST%\%TITLE%.flac"
)
#echo OFF &SETLOCAL ENABLEDELAYEDEXPANSION
for %%i in (*.flac) do (
set /a N+=1
FOR /f "tokens=1,2 delims=- " %%o IN ("%%~ni") DO (
set "FilesA[!N!]=%%~o"
set "FilesB[!N!]=%%~p"
)
)
for /l %%x in (1,1,%N%) do echo(!FilesA[%%x]! !filesB[%%x]!
Thanks for the answers ;) Thanks to Kayasax I fixed it
here is the full code:
#echo off
SETLOCAL ENABLEDELAYEDEXPANSION
set SOURCE=C:\music\folder\with\files\
for /f "tokens=1,2 delims=-" %%i in ('dir /b "%SOURCE%\*.flac"') do (
set "folder=%%i"
IF NOT EXIST "%SOURCE%\%%i" (
mkdir "%%i"
)
move "%SOURCE%\%%i-%%j" "%SOURCE%\!folder:~0, -1!\%%i-%%j"
)
pause
