How to map numbers to a variable - batch-file

Question

I have the following script but I want to map the numbers to the variable but do not know how to. So if a user enters 0, I want it to search for the event name NewUser.
#echo off
mode con:cols=40 lines=40
set /p customerID="Enter Customer ID: "
CLS
:MENU
ECHO.
ECHO ...............................................
ECHO PLEASE SELECT THE EVENT FROM THE MENU BELOW
ECHO ...............................................
ECHO.
ECHO Event Code Event Name
ECHO.
ECHO 0 NewUser
ECHO 1 ExistingUser
ECHO 2 EmailAdded
ECHO 3 AccountProblem
ECHO 4 Lost
ECHO.
SET /P event=Type the event code and then press ENTER:
IF %event%==0 set event=NewUser GOTO find
IF %M%==1 set event=ExistingUser GOTO find
IF %M%==2 set event=EmailAdded GOTO find
IF %M%==3 set event=AccountProblem GOTO find
IF %M%==4 set event=Lost GOTO find
pause
:find
pause
setlocal enableextensions disabledelayedexpansion
pause
set "sourceFolder=C:\test"
set "targetFolder=C:\test2"
pause
set "customerID=%customerID%"
set "NewUser=%Event%"
pause
for /f "delims=" %%a in ('
findstr /m /s /l /c:"%customerID%" "%sourceFolder%\*"
^| findstr /f:/ /m /l /c:"%event%"
') do (
copy "%%~fa" "%targetFolder%"
)
pause

Answer 1

The first version of your code was closer to correct solution than current one; you need to use two nested for /F loops as follows:
for /f "delims=" %%a in ('
findstr /I /m /s /l /c:"%customerID%" "%sourceFolder%\*.txt"
') do for /f "delims=" %%A in ('
findstr /I /m /l /c:"%event%" "%%~fa"
') do (
rem 'copy' command is merely displayed using ECHO for debugging purposes
ECHO copy "%%~fa" "%targetFolder%"
)
Next commented code snippet could help to improve the script:
#ECHO OFF
SETLOCAL EnableExtensions DisableDelayedExpansion
set "customerID="
:customerID
set /p customerID="Enter Customer ID: "
if not defined customerID goto :customerID
REM instead of above test, you could apply next statement about `set /P`:
REM If the user does not enter anything (just presses return)
REM then the variable will be unchanged and an ERRORLEVEL will be set.
rem CLS
:MENU
ECHO.
ECHO ...............................................
ECHO PLEASE SELECT THE EVENT FROM THE MENU BELOW
ECHO ...............................................
ECHO.
ECHO Event Code Event Name
ECHO.
ECHO 0 NewUser
ECHO 1 ExistingUser
ECHO 2 EmailAdded
ECHO 3 AccountProblem
ECHO 4 Lost
ECHO.
REM SET /P M=Type the event code and then press ENTER:
choice /C 01234 /M "Type the event code"
REM 0 means that an user's reply to "Terminate batch job (Y/N)?" was not "y"
IF %ERRORLEVEL% EQU 0 echo "Ctrl-C" or "Ctrl-Break" pressed&goto :NoSearch
REM 255 means another error
IF ERRORLEVEL 255 goto :MENU
REM ERRORLEVEL number Specifies a true condition if the last program run
REM returned an exit code EQUAL TO OR GREATER THAN the number
REM specified.
IF ERRORLEVEL 1 set "event=NewUser"
IF ERRORLEVEL 2 set "event=ExistingUser"
IF ERRORLEVEL 3 set "event=EmailAdded"
IF ERRORLEVEL 4 set "event=AccountProblem"
IF ERRORLEVEL 5 set "event=Lost"
REM Note that in above code, ERRORLEVEL parameters are tested in INCREASING order
REM Used only in this special case
REM (no need of GOTO statement, 'event' variable is set correctly)
REM
REM although CHOICE /? says:
REM When you use ERRORLEVEL parameters in a batch program,
REM list them in decreasing order.
:NOTE
set "sourceFolder=D:\test"
set "targetFolder=D:\test2"
rem ??? set "customerID=%customerID%"
rem ??? set "event=%event%"
rem debugging output
echo looking for "customerID=%customerID%" "event=%event%"
for /f "delims=" %%a in ('
findstr /I /m /s /l /c:"%customerID%" "%sourceFolder%\*.txt"
') do for /f "delims=" %%A in ('
findstr /I /m /l /c:"%event%" "%%~fa"
') do (
rem 'copy' command is merely displayed using ECHO for debugging purposes
ECHO copy "%%~fa" "%targetFolder%"
)
:NoSearch
pause

Answer 2

Change your For loop like this and retest:
FOR /F "DELIMS=" %%A IN (
'FINDSTR/MSC:"%customerID%" "%sourceFolder%\*"^|FINDSTR/MIF:/ /C:"%event%"'
) DO COPY "%%A" "%targetFolder%"
EDIT
I have added a modified version of your script to include the new requirement of a three digit event code. Just adjust it's value in the script as necessary, (lines nineteen to twenty three).
#ECHO OFF
MODE CON:COLS=52 LINES=40
SETLOCAL ENABLEEXTENSIONS DISABLEDELAYEDEXPANSION
(SET sourceFolder=C:\test)
(SET targetFolder=C:\test2)
SET /P "customerID=Enter Customer ID: "
:MENU
CLS
ECHO=
ECHO= ..................................................
ECHO= PLEASE SELECT THE OPTION FROM THE EVENT MENU BELOW
ECHO= ..................................................
ECHO=
ECHO= Option Event Name Event Code
ECHO=
ECHO. 1. NewUser A00
ECHO. 2. ExistingUser A01
ECHO. 3. EmailAdded A02
ECHO. 4. AccountProblem A03
ECHO. 5. Lost A04
ECHO=
CHOICE /C 12345 /M "CHOOSE AN OPTION"
SET "Option=%ERRORLEVEL%"
FOR /F "TOKENS=1-4 DELIMS=. " %%A IN ('FINDSTR/BC:"ECHO. " "%~f0"'
) DO IF "%%B"=="%Option%" (SET "Name=%%C" & SET "Code=%%D")
FOR /F "DELIMS=" %%A IN (
'FINDSTR/MISC:"%customerID%" "%sourceFolder%\*"^|FINDSTR/MIF:/ /C:"%Name%"'
) DO COPY "%%A" "%targetFolder%"
PAUSE
Please make sure that %sourceFolder% is a full path and %targetFolder% already exists, (see line six).
