Listing matrix from batch file - batch-file

I need to make batch file that takes two arguments.
First is txt file containing matrix A containing integer values delimited by ','.
Second argument is also txt file. It containts array B of integers delimited by ' '.
Batch file should create file named result.txt which contains matrix C, where
C[i][j]=A[i][j]+k[i][j] where k[i][j] is number of occurrence number A[i][j] in array B. I would be very thankful if anyone could help me. I tried to solve this but for command in dos is killing me...
For example:
matrix.txt
1,2,3
4,5,6
array.txt
1 3 2 5 1
results.txt
3 3 4
4 6 6

This problem is interesting! This is how I would solve it:
rem Count the number of times each number appear in array B
for each line in %2 do (
for each number %%n in line do (
add 1 to times[%%n]
)
)
rem Process the matrix A
for each line in %1 do (
rem Initialize output line
set "out="
for each number %%n in line do (
set termC = %%n + times[%%n]
join termC to out
)
echo out
)
EDIT: As user aschipfl indicated, this answer is just the pseudo-code of how to solve this problem that I posted as a hint for you (because post complete solutions when the OP had not showed his/her own efforts to solve the problem is not a good practice here).
However, now that another working solution had been posted, I completed previous pseudo-code into a fully working program:
#echo off
setlocal EnableDelayedExpansion
rem Check the arguments
if "%~2" equ "" echo Usage: %~NX0 MatrixA.txt ArrayB.txt & goto :EOF
if not exist "%~1" echo MatrixA file not found & goto :EOF
if not exist "%~2" echo ArrayB file not found & goto :EOF
rem Count the number of times each number appear in array B
for /F "usebackq delims=" %%b in ("%~2") do (
for %%n in (%%b) do (
set /A "times[%%n]+=1"
)
)
rem Process the matrix A and create matrix C
(for /F "usebackq delims=" %%a in ("%~1") do (
set "out="
for %%n in (%%a) do (
set /A termC=%%n + times[%%n]
set "out=!out! !termC!"
)
echo !out:~1!
)) > result.txt

#echo off
setlocal enabledelayedexpansion
for /f "usebackq delims=" %%a in ("path+array.txt") do (
set "array_all=%%a"
)
set array_n=0
call :sub_2 %array_all%
set array_n_all=%array_n%
for /f "usebackq delims=" %%a in ("path+matrix.txt") do (
set "current_line=%%a"
set "current_line=!current_line:,= !"
set "matrix_new="
call :sub_1 !current_line!
echo !matrix_new:~1!>>"path+results.txt"
)
exit /b
:sub_1
set "current_value=%1"
if not defined current_value exit /b
set "array_rest=!array_all:%current_value%=!"
set array_n=0
call :sub_2 %array_rest%
set /a current_value_new=%current_value%+%array_n_all%-%array_n%
set "matrix_new=%matrix_new% %current_value_new%"
shift
goto sub_1
:sub_2
set "array_tmp=%1"
if not defined array_tmp exit /b
set /a array_n+=1
shift
goto sub_2

Can't get value from array in BAT file

I have this code:
#echo off
setlocal EnableDelayedExpansion
rem FILL ARRAY
set n=0
for %%a in (A B C) do (
set fname[!n!]=%%a
set /A n+=1
)
rem FIRST OUTPUT
for /L %%i in (0,1,2) do (
echo !fname[%%i]!
)
echo/
rem SECOND OUTPUT
echo !fname[0]!
echo !fname[1]!
echo !fname[2]!
echo/
rem THIRD OUTPUT DOESN'T WORK
set n=0
for %%a in (A B C) do (
echo !fname[!n!]!
set /A n+=1
)
And get:
A
B
C
A
B
C
n
n
n
For some reasons I need output in third style and expect the same output like in first and second case but I can't understand what's wrong with it.
Update.
Thank you, folks. I guess I've confused you a little but really I need to use this output in variable, so I've found this working solution, maybe it'll help somebody else:
rem THIRD OUTPUT WORKS
set n=0
for %%a in (A B C) do (
for /f "tokens=2* delims==" %%x in ('set fname[!n!]') do (
<... using %%x...>
)
set /A n+=1
)
rem %%x contains output now and can be used anywhere
You need another layer of parsing.
call echo %%fname[!n!]%%
or
for %%n in (!n!) do echo !fname[%%n]!
cures your third case.
Incorporated into your script:
#echo off
setlocal EnableDelayedExpansion
rem FILL ARRAY
set n=0
for %%a in (A B C) do (
set fname[!n!]=%%a
set /A n+=1
)
rem skip first and second output
rem THIRD OUTPUT WORKS
set n=0
for %%a in (D E F) do (
call echo Copy "%%a" "%%fname[!n!]%%"
for %%n in (!n!) do ECHO cOpy "%%a" "!fname[%%n]!"
for /f "tokens=1* delims==" %%x in ('set fname[!n!]') do echo coPy "%%a" "%%y"
set /A n+=1
)
of course use just one of the three lines (and don't forget to remove the ECHO after troubleshooting)

Assign each line of the text file to a variable to verify numbers are in sequence in windows batch script

I'm learning windows batch-file script and creating my own scripts to practice the coding but kind of hit a block while try find whether the numbers in a text file is in sequence or not.I have two files,one file(file.txt) contains the number of lines in file_received.txt. The file_received.txt content is below:
1021
1022
1023
1024
1025
1027
1028
I'm building a script to test whether all the numbers in the text file are in sequence .so as a first step I'm trying to extract each line of the file_received to be assigned to a variable through if / for loop but the if command loop assigning all the lines to the variable num from file_received.txt at the same time. Is it possible to assign first line of the file to variable num and increment it as the if loops increment?
setlocal EnableDelayedExpansion
rem assign the number of lines to a variable
set /P var=<C:\files.txt
for /F "tokens=1" %%a in ("%var%") do echo.%%a
rem assign the first variable to var1
set /P var1=<C:\files_received_sequence.txt
for /F "tokens=1" %%a in ("%var1%") do echo.%%a
set /a x=1
:while
if %x% leq %var% (
echo %x%
rem assigning each line to the variable num inside the if loop and will be used in comparison and reser
for /F "tokens=%x%" %%i in (C:\files_received.txt) do set num=%%i
echo %num%
set /a x+=1
goto :while
)
echo test :D
the output is as below in loop 1 the entire file content is assigned to the variable num and from loop 2 to 7 the last number is assigned.
C:\>setlocal EnableDelayedExpansion
C:\>set /P var= 0<C:\files.txt
C:\>for /F "tokens=1" %a in ("7 ") do echo.%a
C:\>echo.7
7
C:\>set /P var1= 0<C:\files_received.txt
C:\>for /F "tokens=1" %a in ("1021") do echo.%a
C:\>echo.1021
1021
C:\>set /a x=1
C:\>if 1 LEQ 7 (
echo 1
for /F "tokens=1" %i in (C:\files_received.txt) do set num=%i
echo
set /a x+=1
goto :while
)
1
C:\>set num=1021
C:\>set num=1022
C:\>set num=1023
C:\>set num=1024
C:\>set num=1025
C:\>set num=1027
C:\>set num=1028
ECHO is on.
C:\>if 2 LEQ 7 (
echo 2
for /F "tokens=2" %i in (C:\files_received.txt) do set num=%i
echo 1028
set /a x+=1
goto :while
)
2
1028
Here's the logic I'd use to test that each number is in sequence incrementing by one (and only one) each time:
#Echo off & Setlocal EnableDelayedExpansion
Set "ln="
For /F "Delims=" %%i in (C:\file_received.txt) Do (
If Not "!ln!"=="" For /F "UseBackQ Delims=" %%v in (`"Set /A Nx=!ln!+1"`) Do (If Not "%%i"=="%%v" (Echo/OoS:!ln!/%%i & Goto :False))2> Nul
Set "ln=%%i"
)
Echo/True
Exit /B 0
:False
Echo/False
Exit /B 1
Here is a version that will highlight the item not in sequence. Do note, that it will test sequence only, in other words ensure the previous result is lower than the next
#echo off & setlocal enabledelayedexpansion
set rev=-1
for /f "delims=" %%a in (files_received.txt) do for %%i in (%%a) do (
if %%i leq !rev! (
echo %%i Out of sequence
) else (
echo %%i
set rev=%%i
)
)
besides you don't use delayed expansion (although you have enabled it), your logic is far too complicated:
#echo off
setlocal enabledelayedexpansion
set last=-1
for /f %%a in (t.txt) do (
if %%a lss !last! (
echo not in sequence
goto :eof
)
set "last=%%a"
)
echo all in sequence.
the variable !last! holds the value from the previous iteration of the loop.
(Depending on your needs, you may want to replace lss with leq)

Removing carriage returns from a text file using a batch file based on a value

I have a text file that I would like to edit and therefore would like to remove the last line. I have the following code for this:
for /f "delims=" %%a in (input.txt) do (
echo/|set /p ="%%a%"
)>>output.txt
input:
GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;
GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;
GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;
GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;
GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;
GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;
output:
GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEB;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;
Now I would like to edit the data in groups for example by the first value, so that I have the following output:
GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;GRUPPEA;123;12345;sdfdsfds;sdfdsfsdfs;sdfsdfafsf;

If I replace the FOR /F "delims=" %%a in (input.txt) do … loop with an equivalent FOR %%a in … loop:
#ECHO OFF
SETLOCAL EnableExtensions EnableDelayedExpansion

The script counts the number of lines using FINDSTR /N and a FOR /F loop to count the # of lines, which is required to execute SET /P that many times.
Tips:
Use ECHO( instead of the problematic ECHO.
Using a pipe | is very slow, as described by #jeb here. Use <nul instead

New CSV by combining 2 csv files

I have 2 CSV files that has
File1:
Column1,column2
data1, data2
File2:
Column3,column4, column5,column6
data3,data4,data5,data6
I have to create a new CSV file that combines both columns from file 1 with the 1st and 3rd columns from file 2 (4 total columns).
Column1,column2,column3,column5
data1,data2,data3,data5
I am looking to do this using batch file commands. Any suggestions?
Code i am using helps me copy one file.
#ECHO OFF
SETLOCAL
(
FOR /f "tokens=1-3delims=," %%a IN (file1.csv) DO (
ECHO(%%a,%%c
)
)>new.csv
GOTO :EOF
How about following script?
File1.csv :
column1,column2
data1,data2
data3,data4
data5,data6
File2.csv :
column3,column4,column5,column6
data3,data4,data5,data6
data7,data8,data9,data10
Script :
#echo off
setlocal enabledelayedexpansion
set ct1=0
for /f "tokens=*" %%i in (File1.csv) do (
set /a ct1+=1
set ar1[!ct1!]=%%i
)
set ct2=0
for /f "tokens=*" %%i in (File2.csv) do (
set /a ct2+=1
set ar2[!ct2!]=%%i
)
if !ct1! lss !ct2! (
set ct=!ct2!
) else (
set ct=!ct1!
)
for /l %%i in (1,1,!ct!) do (
echo !ar1[%%i]!,!ar2[%%i]!>> new.csv
)
new.csv :
column1,column2,column3,column4,column5,column6
data1,data2,data3,data4,data5,data6
data3,data4,data7,data8,data9,data10
data5,data6,
Here is a pure batch solution that works, but with the following limitations and or assumptions:
File 1 lines are terminated by carriage return and linefeed (Windows style)
File 1 lines are no longer than 1021 bytes
File 2 must have a value for each column (no consecutive commas)
File 2 line lengths never exceed ~8191 bytes
File 2 does not have any quoted column values that include commas.
Files 1 and 2 have the same number of lines
Neither file has quoted data values that include new lines (rare, but possible within a CSV).
#echo off
setlocal disableDelayedExpansion
<"file1.csv" >"merged.csv" (
for /f "usebackq eol=, delims=, tokens=1,3" %%A in ("file2.csv") do (
set /p "part1="
set "part2=%%A,%%B"
setlocal enableDelayedExpansion
echo !part1!,!part2!
endlocal
)
)
A much more robust and faster solution is possible if you use PowerShell, JScript, or VBS.
You can also implement an efficient and robust solution using JREPL.BAT - a regular expression text processing utility. JREPL.BAT is pure script (hybrid batch/JScript) that runs natively on any Windows machine from XP onward. Full documentation is available from the command line via jrepl /?, or jrepl /?? for paged help.
This JREPL solution has only the following reasonable limitations:
Files 1 and 2 must have the same number of lines
Neither file has quoted data values that include new lines
#echo off
setlocal
set "col=\q(?:\q\q|[^,\q])*\q|[^,]*"
call jrepl "^(%col%),(?:%col%),(%col%)(?:,.*|$)" ^
"$txt=stdin.ReadLine()+','+$1+','+$2" ^
/jq /x /f "file2.csv" /o "merged.csv" <"file1.csv"
This flexible script does what you want, given that the following restrictions are not violated:
both files must contain the same number of lines;
the number of columns per line/row must be equal per each file;
lines are no longer than 1023 bytes, including the terminating line-break;
field/cell values must not contain line-breaks;
each line/row must be terminated by Windows-style line-breaks (CR+LF);
the given column numbers to copy must be sorted in ascending order;
So here is the code:
#echo off
setlocal EnableExtensions DisableDelayedExpansion

Batch For loop array

Okay so here is what I have.
#echo off
setLocal EnableDelayedExpansion
:begin
set /a M=0
set /a number=0
set /p Input=You:
echo %Input% >> UIS
for /F "tokens=1 delims= " %%i in ("%Input%") do (
set /a M+=1
set i!M!=%%i
)
del UIS 1>nul 2>nul
:loop
set /a number+=1
set invar=!i%number%!
echo %invar%
pause > nul
goto loop
Say, for example, the Input string was "Lol this is my input string"
I want the for loop to set i!M! where M = 1 to "Lol", where M = 2 i!M! is "this" and where M = 3 i!M! is "is" and so on. Now, of course, this can't go on forever, so even if I have to stop when M = 25 or something, and say the string was only 23 words long. Then when M = 24 and 25 then i!M! is simply null or undefined.
Any help is appreciated, thank you.
for /f reads line by line, not word by word.

if "!teststring!" EQU "" goto displayloop
for /f "delims= " %%a in ("!teststring!") do set substring=%%a
set /a M+=1
set i!M!=!substring!
REM Now strip off the leading substring

for /F command divide a line in a definite number of tokens that must be processed at once via different replaceable parameters (%%i, %%j, etc). Plain for command divide a line in an undefined number of words (separated by space, comma, semicolon or equal-sign) that are processed one by one in an iterative loop. This way, you just need to change this for:
for /F "tokens=1 delims= " %%i in ("%Input%") do (
by this one:
for %%i in (%Input%) do (
PS - I suggest you to write the array in the standard form, enclosing the subscript in square brackets; it is clearer this way:
set i[!M!]=%%i
or
set invar=!i[%number%]!
