I have the following file contents from which I want to extract the MD5 hash value thats on line 2.
How can I do this in a Windows batch file? Unfortunately using powerscript is not an option.
Herewith the input file ( file.txt )
MD5hashoffile20160613190010_Address
f4f855c5cb40767a7227b506f641ceef
CertUtil:-hashfilecommandcompletedsuccessfully.
I wanted to use the findstr utility but the regex I use must be wrong since it's not returning anything.
findstr /R "[a-fA-F0-9]{32}" file.txt
I appreciate any advice.
Thanks
UPDATE :
I have added the full solution in the answer section.
After some trial and error I found a solution that works :
findstr /R "^[a-fA-F0-9]*$" file.txt
Updated Answer with full solution :
SETLOCAL ENABLEDELAYEDEXPANSION
SET "FILESIZE=0"
SET "RECORDCOUNT=0"
SET "MD5HASH="
SET "TEMPHASH="
SET "FILESETREPORT=_UNSET"
SET "LINE=0"
SET "COLUMNS=TableName|RecordCount|FileSize|FileHash"
echo "============================="
echo "= Starting FileSize process ="
echo "============================="
for %%F in (*.csv) do (
echo "Process A CSV File"
for /f "tokens=1,2,3,4 delims=^_" %%A IN ("%%~nF") do (
SET "TABLENAME=%%D"
SET "FILESIZE=%%~zF"
if "!FILESETREPORT!" == "_UNSET" (
SET "FILESETREPORT=%%A_%%B_%%C_FilesetReport.csv"
:: Initialize the headers
echo !COLUMNS! > !FILESETREPORT!
)
)
echo "Get RecordCount in CSV"
if "!TABLENAME!" NEQ "FilesetReport" (
for /f "tokens=*" %%I in ('more +1 %%F ^| find /v /c ""') do SET "RECORDCOUNT=%%I"
echo "Generate File MD5 Hash"
certUtil -hashfile %%~nxF MD5 > hashfile
echo "Get the hash from the file"
for /f "skip=1 tokens=*" %%A in (hashfile) do (
SET "TEMPHASH=%%A"
:: call :cleanHash
if !LINE! == 0 SET "LINE=1" && call :cleanHash
)
:: Reset the Line Number
SET "LINE=0"
echo "Save File Details to FieldsetReport"
echo "RecordCount : !RECORDCOUNT!"
echo "FileSize : !FILESIZE!"
echo "MD5Hash : !MD5HASH!"
echo "TableName : !TABLENAME!"
SET "OUTPUTLINE=!TABLENAME!|!RECORDCOUNT!|!FILESIZE!|!MD5HASH!"
echo !OUTPUTLINE! >> !FILESETREPORT!
:: Cleanup
del hashfile
)
)
echo "File Processing Completed"
exit /b 0
:cleanHash
echo "Remove all spaces from the MD5 hash"
:: for /f "delims=" %%a in ('findstr /R "^[a-fA-F0-9]*$" !TEMPHASH!') do SET TEMPHASH=%%a
SET "MD5HASH=!TEMPHASH: =!"
echo "********************************************************************"
echo !MD5HASH!
ENDLOCAL
You're better off using this:
#echo off
for /f "skip=1" %%a in (file.txt) do set "hash=%%a" &goto breakLoop
:breakLoop
echo %hash%
pause
This should work even if another line also contains only hexadecimal characters, and has the added benefit of putting the md5 hash in a variable, ready to be used.

I am completely new to .bat code. I want to merge two csv file based on common column and selective columns for the output file.
For ex
file1.csv
id,name,roll
1,x,12
2,y,13
file2.csv
id,class,subject
1,V,english
2,III,Math
Output will be
result.csv
id,name,class,subject
1,x,V,english
2,y,III,Math
Below is the code I started. My problem is how to use the common column and select the column.
#echo off
set "tmpfile=%temp%\result.tmp"
set "csvfile=result.csv"
copy nul "%tmpfile%" >nul
echo.
echo Processing all CSV files...
set "header="
for %%a in (%1) do (
if not "%%a"=="%csvfile%" (
set /p =Processing %%a...<nul
for /f "tokens=1* usebackq delims=," %%b in ("%%a") do (
if /i "%%b"=="Keyword" (
if not defined header (
set /p =Found header...<nul
set "header=%%b,%%c"
)
) else (
title [%%a] - %%b,%%c
findstr /b /c:"%%b" /i "%tmpfile%">nul || echo %%b,%%c>>"%tmpfile%"
)
)
echo OK
)
)
echo Finished processing all CSV files
echo.
echo Creating %csvfile%
echo %header%>"%csvfile%"
set /p =Sorting data...<nul
sort "%tmpfile%">>"%csvfile%"
echo OK
del "%tmpfile%"
echo Finished!
title Command Prompt
exit /b
The problem description lacks multiple details and the example code provided has no relation to the description. In the description you talk about two files but in the code you process "all CVS files" with no indication of which "two files" should be merged. The code has an undescribed "Keyword" value. The code sorts the output file, but this is not necessary because "both input files are sorted by common column" as you said...
Anyway I tried to help you writting a working code that achieve what you said in the problem description. I searched for "file merge" in the Batch-file tag and get multiple results, so I just used this method as base...

I have a text file that looks like this:
Dog
Cat
Frog
Bat
Bird
Mouse
I want to attribute a number to each string, each line.
So that it becomes
1 Dog
2 Cat
3 Frog
4 Bat
5 Bird
6 Mouse
Then I want to ask the user to input a number, and then have the corresponding string stored in the variable.
So if the user inputs 1, then the variable is set to the string Dog
So when the user inputs 1 the program stores/outputs Dog
set /p var1="number? " so var1 becomes the string, not the number.
This does the first part of the task kinda, but now I need the second part, storing the strings in avariable.
#echo off
set TEXT_T="list.txt"
set /a c=0
setlocal ENABLEDELAYEDEXPANSION
FOR /F "tokens=1 usebackq" %%i in (%TEXT_T%) do (
set /a c=c+1
echo !c! %%i
)
endlocal
pause
Here below is an updated answer, thanks to LotPings.
With a small tweak to ask for the folder by string
This provides an easier way to use Megatools from CMD
https://megatools.megous.com/man/megals.html
https://github.com/megous/megatools
#echo off
:start:
megals /Root/
set /p var1="dir? " & megals /Root/%%var1%%
for /f "tokens=1,* delims=:" %%A in ('megals -n /Root/%%var1%% ^|findstr
/n "." ') do (
set Link[%%A]=%%B
Echo %%A %%B
)
for /f "tokens=1,* delims=:" %%A in ('megals -n -e /Root/%%var1%% ^|findstr
/n "." ') do (
set Link[%%A]=%%B
)
set /p choice=Select #:
Call Set Link=%%Link[%choice%]%%
set "trimmedlink="
for %%h in (%Link%) do if not defined trimmedlink set "trimmedlink=%%h"
Megadl %trimmedlink% && goto :start:
pause
Edit: Had to trim %Link% to just the first word, i.e just the link
The output of Megals -e /Root/misc looks like this:
The asterisk are the unique link ids for the files
/Root/misc
https://mega.nz/#!********!********************* /Root/misc/File1
https://mega.nz/#!********!********************* /Root/misc/File2
https://mega.nz/#!********!********************* /Root/misc/File3
With the batch script above it looks like:
1 File1
2 File2
3 File3
Select #: <------input file number
Edit2 number listing is fixed
Edit3 Parentheses in filenames crash the program
i.e
1 File(1)
The chosen file number then gets passed to Magadl as the corresponding link
Megadl Link
The batch script allows you to download the link by just entering the corresponding file number so you don't have to type out the long link id in a standard cmd window.
To use megals output directly and avoid delayedexpansion (which removes the !)
Findstr /n will do the numbering.
#echo off
for /f "tokens=1,* delims=:" %%A in ('megals -e /Root/ ^|findstr /n "." ') do (
set Item[%%A]=%%B
Echo %%A %%B
)
set /p choice=Select #:
Call Echo Choice:%%Item[%choice%]%%
Using a (pseudo-)call with doubled percent signs is an old fashioned method of realizing delayed expansion without the problem with the !.
In programming/scripting you need to adapt techniques to fit your needs.
Without knowing the exact output of your megatools,
this could do the job :
#echo off
for /f "tokens=1,* delims=:" %%A in ('megals -e /Root/ ^|findstr /n "." ') do (
set Folder[%%A]=%%B
Echo %%A %%B
)
set /p choice=Select #:
Call Set Folder=%%Folder[%choice%]%%
for /f "tokens=1,* delims=:" %%A in ('megals -e %Folder% ^|findstr /n "." ') do (
set Link[%%A]=%%B
Echo %%A %%B
)
set /p choice=Select #:
Call Set Link=%%Link[%choice%]%%
megadl %Link%
As compo advised, please edit your question to contain all necessary information - don't force others to gather it from unnecessary answer and comments.
Just use an array:
#echo off
setlocal ENABLEDELAYEDEXPANSION
set TEXT_T="list.txt"
set /a c=0
FOR /F "tokens=1 usebackq" %%i in (%TEXT_T%) do (
set /a c=c+1
echo !c! %%i
set string[!c!]=%%i
)
set /P number=Enter number:
echo !string[%number%]!
pause
For further details, see this answer.
What about making the output of a command into a list, instead of a text file into a list?
so the line with var1 here would be turned into a numbered list (the files listed in that directory), and Var2 is the number the users enters to create the returned string that gets passed to a command. i.e
https://megatools.megous.com/man/megals.html
#echo off
SETLOCAL ENABLEDELAYEDEXPANSION
(megals -e /Root/) <--------list all folders in root
(set /p var1="dir? " && megals -e /Root/!var1!) <-- select folder + list files
(set /p var2="Megalink? " && Megadl !var2!) <--- enter the file name for download
ENDLOCAL
pause
I want to be able to enter a number for the download, instead of the long file name. So this way the user can enter the number that corresponds to the link that they want to download. So if they enter 1 then the program does Megadl Dog
#echo off
SETLOCAL ENABLEDELAYEDEXPANSION
megals -e /Root/
set /p var1="dir? "
megals -e /Root/!var1! > rlist.txt
set TEXT_T="rlist.txt"
set /a c=0
FOR /F "tokens=1 usebackq" %%i in (%TEXT_T%) do (
set /a c=c+1
echo !c! %%i
set string[!c!]=%%i
)
set /P number=Enter number:
Megadl !string[%number%]!
Endlocal
pause
This kills the first part of the link because it removes everything in between and including exclamations. !dasasdasd!
all megalinks start with #!something!
This didn't work
I need output of Call Echo %%Item[%choice%]%% passed to Megadl
#echo off
for /f "tokens=1,* delims=:" %%A in ('megals -e /Root/anime ^|findstr /n "." ') do (

Echo %%A %%B
)
set /p choice=Select #:
Call Echo %%Item[%choice%]%%
for /F "tokens=*" (`%%Item[%choice%]%%`) do (
set "var1=%%A"
Megadl !Var1!
)

I wrote a very simple script to output the host machine's MAC addresses to a text file.
The script is exiting right after line 3 - 'IF DEFINED WRITEOK ('.
#echo off
cls
copy /Y NUL "%CD%\.writable" > NUL 2>&1 && set WRITEOK=1
IF DEFINED WRITEOK (
rem ---- we have write access ----
set DIR=%CD%\interfaces
set FILE=%DIR%\%USERNAME%.txt
IF NOT EXIST "%DIR%" (
MKDIR "%DIR%"
echo DIR '%DIR%' was created
) else (
echo DIR '%DIR%' already exists
) for /f "tokens=2 delims=:" %%i in ('ipconfig /all ^| findstr /i "Physical Host"') do (
echo %%i >> "%FILE%"
echo OUTPUT written to '%FILE%'
)
) else (
rem ---- we don't ----
echo DIR '%DIR%' is not writable
)
echo.
echo DONE!
pause
Try to put the FOR one line after the closing parenthesis :
...)
for /f "tokens=2 delims=:" %%i in ('ipconfig /all ^| findstr /i "Physical Host"') do (...
you can't start a FOR with a closing parenthesis in front :
This will not work :
(echo 1
) for /l %%a in (1,1,10) do echo %%a
and this will work :
(echo 1
)
for /l %%a in (1,1,10) do echo %%a
EDIT 1 :
For the path variables containing space use double quote :
"%cd%"
when using it.
I am trying to replace a line in load.xml using the lines read from FileList.txt.
Contents of load.xml
<mainheader>

FileList.txt
newfile1.txt
newfile2.txt
Expecting the output with each iteration as
<mainheader>
<InFilePath>D:\Data\All_Inputfiles\newfile1.txt</InFilePath>
</mainheader>
and with the next iteration replace newfile1.txt with newfile2.txt. I am able to get original string with the final string but last part of the code is throwing syntax error, i.e. from
for /f "delims=" %%a in (!INTEXTFILE!) do call :Change "%%a" .
Could please help me?

this batch script to search file better
using "find" its just ordinary...and need to type exactly the file name "file 1.txt" "file2.txt" "file letter.txt"
and exactly folder location...
any other way?
just try type "file"
its show all file with name "file"
"file 1.txt"
"file2.txt"
"file letter.txt"
and have number
1 . "file 1.txt"
2 . "file2.txt"
3 . "file letter.txt"
and enter the number to select the file what we want...
and it will be open.

any suggestion?
you might try this:
