I want to find a string in a file using DOS:
For example
find "string" status.txt
And when it is found, I want to run a batch file.
What is the best way to do this?
It's been awhile since I've done anything with batch files but I think that the following works:
find /c "string" file
if %errorlevel% equ 1 goto notfound
echo found
goto done
:notfound
echo notfound
goto done
:done
This is really a proof of concept; clean up as it suits your needs. The key is that find returns an errorlevel of 1 if string is not in file. We branch to notfound in this case otherwise we handle the found case.
C:\test>find /c "string" file | find ": 0" 1>nul && echo "execute command here"
#echo off
cls
MD %homedrive%\TEMPBBDVD\
CLS
TIMEOUT /T 1 >NUL
CLS
systeminfo >%homedrive%\TEMPBBDVD\info.txt
cls
timeout /t 3 >nul
cls
find "x64-based PC" %homedrive%\TEMPBBDVD\info.txt >nul
if %errorlevel% equ 1 goto 32bitsok
goto 64bitsok
cls
:commandlineerror
cls
echo error, command failed or you not are using windows OS.
pause >nul
cls
exit
:64bitsok
cls
echo done, system of 64 bits
pause >nul
cls
del /q /f %homedrive%\TEMPBBDVD\info.txt >nul
cls
timeout /t 1 >nul
cls
RD %homedrive%\TEMPBBDVD\ >nul
cls
exit
:32bitsok
cls
echo done, system of 32 bits
pause >nul
cls
del /q /f %homedrive%\TEMPBBDVD\info.txt >nul
cls
timeout /t 1 >nul
cls
RD %homedrive%\TEMPBBDVD\ >nul
cls
exit
We have two commands, first is "condition_command", second is "result_command".
If we need run "result_command" when "condition_command" is successful (errorlevel=0):
condition_command && result_command
If we need run "result_command" when "condition_command" is fail:
condition_command || result_command
Therefore for run "some_command" in case when we have "string" in the file "status.txt":
find "string" status.txt 1>nul && some_command
in case when we have not "string" in the file "status.txt":
find "string" status.txt 1>nul || some_command
As the answer is marked correct then it's a Windows Dos prompt script and this will work too:
find "string" status.txt >nul && call "my batch file.bat"
That's more straightforward:
find /c "string" file
if %errorlevel% not equ 1 goto something

I have a batch file which searches through a directory tree deleting generated file backups.
I want to edit the script to run the del command against the files found in the search, but I can't get it to work.
I've searched other threads and set it up similarly but without the expected results.
#echo off
pushd FILEPATH
echo Searching directories...
for /f "delims=" %%G in ('dir /b /s *.0**.rfa') do echo "%%G"
echo.
IF /I "%%G" == "" GOTO NOTFOUND
set /P delete="Delete files? [Y/N]: "
IF /I "%delete%" NEQ "Y" GOTO ENDOF
echo Deleting files...
echo.
del "%%G"
echo.
echo Done!
timeout 5
exit
:ENDOF
echo Aborted.
timeout 5
exit
:NOTFOUND
echo Found nothing.
timeout 5
exit
Result:
Deleting files...
Could Not Find FILEPATH\ %G
Done!
Do you really need the for loop? The following should work exactly as you want:
#echo off
dir /b /s "*.0*.rfa" || echo Found nothing. & goto :finish
choice /m "delete all? "
if errorlevel 2 echo Aborted. & goto :finish
echo Deleting files...
del /q /s "*.0*.rfa"
echo Done.
:finish
timeout 5
exit /b
I want to put a 30s time limit for the :choice Y/N/P and after the time is up goto :start
The code I have need help for the timeing thing
#echo off
:start
echo AmishCraft will start
TIMEOUT /T 5
echo (%time%)
java -Xms2048M -Xmx4096M -jar server.jar
call C:\Program Files (x86)\Common Files\Oracle\Java\javapath\java.exe
ping 1.1.1.1 -n 1 -w 3000 >nul
:choice
set /P a=do you want to restart? Yes No Pause [Y/N/P]?
if /I "%a%" EQU "Y" goto :restart
if /I "%a%" EQU "N" goto :stop
if /I "%a%" EQU "P" goto :pause
goto :start
:restart
cls
echo server will restart
cls
goto :start
:stop
cls
echo closing server
TIMEOUT /T 5
exit
cls
echo server is paused
:pause
:choice
set /P a=do you want start? Restart Stop [R/S]?
if /I "%a%" EQU "R" goto :restart
if /I "%a%" EQU "S" goto :stop
goto :start
pause
/T is the timeout switch for choice.
/D is the switch to define the default errorlevel / option to set if the
time Elapses.
Example:
CHOICE /T 5 /N /C 1234 /M "Select Option 1,2,3 or 4" /D 1
Applies a timeout of 5 seconds, with the errorlevel being set to option 1, equal to errorlevel 1 in this instance.
/N Hides the default Choice Prompt String.
/M Allows you to Define your own Prompt string
/C Allows alphanumerical characters to be defined as Choice options
Note:
Errorlevel is Set from Left to Right with regards to listed options.
After the Choice Command Errorlevel Needs to be Assessed From Highest to lowest
OR
Used Directly; Such as in a Goto :LabelName%errorlevel% Command
* Response to comment *
CHOICE /C 123 /T Timeout 25 /D goto :start /M 1 choice menu 25s
IF %ERRORLEVEL% EQU 1 goto :choice1
There are multiple errors in the above.
/T Timeout 25 should be: /T 25
Timeout is implicit in the /T switch and does NOT form a part of correct usage of the choice command.
/D goto :start should be: /D 1 OR /D 2 OR /D 3
Only the defined /C options should be used following the /D switch
/M 1 choice menu 25s is incorrect.
The prompt after /M should be encased in Doublequotes: "[1] Option 1. [2] Option 2. [3] Option 3."
Errorlevel Assessment should be done on the Line After the CHOICE Command.
Again, to be clear, Assesment should be done from Highest to Lowest. When errorlevel is Assessed following Choice it is actually interpreted as If ERRORLEVEL GTR n , Despite being scripted Using If ERRORLEVEL n
An example of the Correct usage of all of the above:
#echo off
:menu
cls
CHOICE /N /T 25 /C 123 /M "[1] Option 1. [2] Option 2. [3] Start." /D 3
IF ERRORLEVEL 3 (
GOTO :start
) else (
GOTO :choice%errorlevel%
)
:start
ECHO( You are at the start
Pause
GOTO :menu
:choice1
ECHO( You are at option 1
Pause
GOTO :menu
:choice2
ECHO( You are at option 2
Pause
GOTO :menu
I am using this batch to automatically restart some program, they are running very well, but sometimes the batch exit, which causes process_1 and process_2 also exit. It seems that everything is normal, but the batch itself crashes. Why ?
#echo off
cd %~dp0
set process_1=process_1.exe
set process_2=process_2.exe
set interval=10
:check_service
tasklist > task_tmp.txt
findstr %process1% task_tmp.txt> NUL
if ErrorLevel 1 (
timeout /t 1 /nobreak > NUL
goto start_1
)
findstr %process2% task_tmp.txt> NUL
if ErrorLevel 1 (
timeout /t 1 /nobreak > NUL
goto start_2
)
timeout /t %interval% /nobreak > NUL
goto check_service
:start_1
start /b "" %process_1%
echo %date% %time% %process_1% " down, up it" >> start_note.txt
goto check_service
:start_2
start /b "" %process_2%
echo %date% %time% %process_2% " down, up it" >> start_note.txt
goto check_service
You can maybe simplify like this:
#echo off
Set "MyProcess1=process_1.exe"
Set "MyProcess2=process_2.exe"
:check
%SystemRoot%\System32\tasklist.exe /NH | %SystemRoot%\System32\find.exe /i "%MyProcess1%">nul || echo starting %MyProcess1% && start "process 1" "%MyProcess1%"
%SystemRoot%\System32\tasklist.exe /NH | %SystemRoot%\System32\find.exe /i "%MyProcess2%">nul || echo starting %MyProcess2% && start "Process 2" "%MyProcess2%"
%SystemRoot%\System32\timeout.exe /t 10 /nobreak >nul
goto check
Full qualified file names are used for the commands tasklist, find and timeout to make this batch file independent on the values of the local environment variables PATH and PATHEXT and to avoid that the Windows command processor has to search for these three executables.
You can shorten your code like this:
#echo off
pushd "%~dp0"
:chkservice
tasklist | find /I "Process_1.exe" >nul 2>&1
if errorlevel 1 (
start Process_1.exe
echo %date% %time% Process_1.exe Down up, it >>startnote.txt
)
tasklist | find /I "Process_2.exe" >nul 2>&1
if errorlevel 1 (
start Process_2.exe
echo %date% %time% Process_2.exe Down up, it >>startnote.txt
)
timeout /t 10 /nobreak >nul 2>&1
goto chkservice
I have created the below code to execute multiple commands depending on the user input but the input is case-sensitive.
I have tried the /I switch with the if statement but that does not work either.
Below is the code:
#Echo off
SET /P uname=Launch Outlook in safe mode:
IF "%uname%"==Yes GOTO Error
IF "%uname%"==No GOTO start
:Error
taskkill /IM Outlook.exe /f
cd c:\Program Files (x86)\Microsoft Office\root\Office16
start Outlook.exe /safe
#echo The Script is running please wait && timeout /t 20
taskkill /IM Outlook.exe /f
cd %Homepath%
cd Appdata\Local\Temp
echo.>myfile.txt && #echo Thanks for using the script,You may close this window.and continue. > myfile.txt
start outlook.exe
timeout /t 8
start notepad myfile.txt
:End
:start
echo "No valid options"
echo "This window would close in 10 seconds" && timeout /t 10
:End
I would use the choice command instead
echo Y] Yes
echo N] No
choice /c yn /n
if %errorlevel%==1 goto yes
if %errorlevel%==2 goto yes
I've spent a few days trying to get this batch script to work, but it just does not seem to work properly. It seems to just do whatever it wants after it prompts me to set a variable and i set it.
For example, I might enter n when it says that it doesn't seem to exist, and it will just end the script like it should. But if I re-open it, and it says the same thing as before, and I enter n again, it might just jump to :DeleteCalc, as if I typed y.
Here's my script:
#echo off
:Begin
color fc
title My script
cls
if not exist "C:\calc.exe" (
echo calc.exe doesn't seem to exist. Attempt deletion anyway? ^(Y/N^)
set "calcnotexist="
set /p "calcnotexist="
::This command checks to see if the user inputs a quotation mark. If they do, it echos that quotes cannot be inputted.
setlocal EnableDelayedExpansion
if not !calcnotexist!==!calcnotexist:^"=! set "calcnotexist="
endlocal & if "%calcnotexist%"=="" (
echo ERROR - Quotes cannot be entered.
pause
goto Begin
)
if /i "%calcnotexist%"=="Y" (
echo.
goto DeleteCalc
)
if /i "%calcnotexist%"=="Yes" (
echo.
goto DeleteCalc
)
if /i "%calcnotexist%"=="N" goto End
if /i "%calcnotexist%"=="No" goto End
echo ERROR - Unrecognized input
pause
goto Begin
)
:calcDoesExist
title My script
cls
echo calc.exe found. Delete? ^(Y/N^)
set "calcexist="
set /p "calcexist="
::This command checks to see if the user inputs a quotation mark. If they do, it echos that quotes cannot be inputted.
setlocal enabledelayedexpansion
if not !calcexist!==!calcexist:^"=! set "calcexist="
endlocal & if "%calcexist%"=="" (
echo ERROR - Quotes cannot be entered.
pause
goto calcDoesExist
)
if /i "%calcexist%"=="Y" goto DeleteCalc
if /i "%calcexist%"=="Yes" goto DeleteCalc
if /i "%calcexist%"=="N" goto End
if /i "%calcexist%"=="No" goto End
echo ERROR - Unrecognized input
pause
goto calcDoesExist
:DeleteCalc
cls
echo Deleting...
if not exist C:\calc.exe goto Success
del /f /q C:\calc.exe >nul 2>nul
if not exist C:\calc.exe goto Success
echo Fail!
echo.
echo calc.exe could not be deleted.
echo.
pause
goto End
:Success
echo Deleted!
echo.
echo calc.exe successfully deleted.
echo.
pause
goto End
:End
exit /b
What could I possibly be doing wrong?
Thanks
P.S. I tested this by opening CMD and running the batch script multiple times in there. (but it also doesn't work right when just double clicking it)
If you restructure your script there will be no need for the extended If blocks and therefore no necessity to EnableDelayedExpansion. Also if you use Choice you will not have to do all of the verification of responses.
Example:
#Echo Off
Title My script
Color FC
:Begin
If Exist "C:\calc.exe" GoTo calcDoesExist
Echo(calc.exe doesn't seem to exist.
Choice /M "Attempt deletion anyway"
If ErrorLevel 3 (ClS & GoTo Begin)
If ErrorLevel 2 GoTo End
If ErrorLevel 1 GoTo Success
GoTo End
:calcDoesExist
Echo(calc.exe found.
Choice /M "Delete"
If ErrorLevel 3 (ClS & GoTo calcDoesExist)
If ErrorLevel 2 GoTo End
If ErrorLevel 1 GoTo DeleteCalc
GoTo End
:DeleteCalc
ClS
Echo(Deleting...
Del /A /F "C:\calc.exe">Nul 2>&1
If Not Exist "C:\calc.exe" GoTo Success
Echo(Fail!
Echo(
Echo(calc.exe could not be deleted.
GoTo End
:Success
Echo(
Echo(Deleted!
Echo(
Echo(calc.exe does not exist.
:End
Echo(
Echo(Exiting...
Timeout 3 /NoBreak>Nul
Exit /B
