Ive been trying to loop a batch file exactly 5 times using the set /a operation and so far no luck! Could someone help me?
#ECHO OFF
set loopCount=0
:loop
echo Checked %loopCount% times...
set /a loopCount=1+%loopCount%
if loopCount == 5 (goto exit) else (goto loop)
:exit
cls
echo Finished after %loopCount% times
pause >nul
Best of luck to whoever can help me
Here's a couple of examples to help you.
Using GoTo with a label:
#Set "loopCount=0"
:loop
#Set /A loopCount += 1
#Rem Some actual command goes here.
#Echo Checked %loopCount% times...
#If %loopCount% Lss 5 GoTo loop
#%SystemRoot%\System32\timeout.exe /T 2 /NoBreak 1>NUL
#ClS
#Echo Finished after being checked %loopCount% times.
#Pause 1>NUL
Alternatively, using a For /L looping mechanism:
#Set "maxCount=5"
#For /L %%G In (1,1,%maxCount%) Do #(
Rem Some actual command goes here.
Echo Checked %%G times...
)
#%SystemRoot%\System32\timeout.exe /T 2 /NoBreak 1>NUL
#ClS
#Echo Finished after being checked %maxCount% times.
#Pause 1>NUL
If you need to execute the entire batch script 5 times, the following method of storing an execution count in an alternate data stream of the script can be used:
#Echo off
more < "%~f0:Count" 2>&1 > nul && (
For /f "usebackq delims=" %%G in (`more ^< "%~f0:Count"`)Do Set /A Count=%%G+1
) || (
Set /A "Count+=1"
)
Echo(%Count% >"%~f0:Count"
:# Your script below
Echo(Script execution: %Count%
:# Terminate script execution after count reached
If %Count% EQU 5 (
Echo(0 >"%~f0:Count"
Exit /B
)
"%~f0"
I haven't changed anything in the file, and it worked perfectly for over a month, but now this delay is really starting to annoy me and I can't for the life of me figure out how to fix it.
#echo off
Setlocal EnableDelayedExpansion
set "Music_PATH=C:\Music\ESmusic"
set counter=0
for /f "tokens=*" %%a in ('forfiles /p "%Music_PATH%" /m *mp3') do (
set Rand_PATH[!counter!]=%%~nxa
set /a counter+=1
)
set /a Random_Music=%random% %% %counter%
set "Full_PATH=%Music_PATH%\!Rand_PATH[%Random_Music%]!"
echo Random Music & echo. & echo !Rand_PATH[%Random_Music%]!
start "" "%Full_PATH%"
Timeout 23
taskkill /f /IM winamp.exe
pause >nul
Here is the file for reference. Any and all help is appreciated!
I want to make timer that makes cmd every 2 sec for 60 sec
timeout/t 60
timeout /t 2
start everlast.bat
timeout /t 2
start everlast.bat
I dont even now how to do it
You should try to explain better what you intend. I simply guess you might try to do something like this.
#Echo off
Echo Start %time%
For /l %%A in (1,1,30) Do Start everlast.bat & Timeout /t 2
Echo End %time%
Edit Added time output to measure elapsed time
If you really want to check the time you would need to convert the current time to seconds to do the calculations.
#echo off
for /F "tokens=1-4 delims=:.," %%a in ("%time%") do set /A "current=(((%%a*60)+1%%b %% 100)*60+1%%c %% 100)"
set /A expire=current + 60
:label
timeout /T 2 >nul
start "" "everlast.bat"
for /F "tokens=1-4 delims=:.," %%a in ("%time%") do set /A "current=(((%%a*60)+1%%b %% 100)*60+1%%c %% 100)"
IF %current% lss %expire% GOTO label
echo off
set /a time=60
:timer
ping localhost -n 2 >nul
set /a time=%time%-1
ping localhost -n 2 >nul
set /a time=%time%-1
start everlast.bat
if %time% LEQ 0 goto EOF
goto timer
:EOF
exit
that should work if i'm correct
Everything before the for loop works fine, i can add "pause" to it and it pauses, but inside the for loop it does not work. I have tried to add pause but it doesn't, and the pause after the loop does not occur.
#echo off
setlocal enabledelayedexpansion
setlocal
for %%g in ( * ) do (
pause
echo %%g
set strEnd=___EndOfString___
set strFilename=%%g
set strFile=!strFilename!!strEnd!
echo !strFile!
pause
:loop
set strChar=!strFile:~0,1!
set strFile=!strFile:~1!
if !strChar!==a echo A
pause
if not !strFile!==!strEnd! goto loop
)
pause
endlocal
This construct should work. You can adjust timeouts duration.
#echo off
setlocal enabledelayedexpansion
for %%g in ( * ) do (echo %%g
set strEnd=___EndOfString___
set strFilename=%%g
set strFile=!strFilename!!strEnd!
echo !strFile!
timeout 2 >nul
call :loop
)
pause
exit /b
:loop
:: add more code here
timeout 2 >nul
exit /b
However, your original script inside the :loop is not correct, and needs to be changed depending on the batch purpose.
I would like to show the user with a spinner, that something is done in background but do not know how this works in a batchfile.
Does anyone have a clue?
This can actually be done quite easily with pure native commands, you just have to know how to use the more tricky of them. No use of external tools like VBScript or nasty side effects like clearing the screen are necessary.
What you're looking for is the equivalent of the bash "echo -n" command which outputs a line without the newline. In XP batch, this is achieved by using "set /p" (ask user for response with a prompt) with empty input as follows:
<nul (set /p junk=Hello)
echo. again.
will output the string "Hello again." with no intervening newline.
That trick (and the use of CTRL-H, the backspace character can be seen in the following test script which starts (one after the other) a 10-second sub-task with a 20-second timeout and a 15-second sub-task with a 10-second timeout.
The payload script is created by the actual running script and its only requirement is that it do the work it has to do then delete a flag file when finished, so that the monitor function will be able to detect it.
Keep in mind that the ^H strings in this script are actually CTRL-H characters, the ^| is two separate characters used to escape the pipe symbol.

If I understand your question you want a spinner because some operation you are performing is taking time and you want to show to the user that something is happening, right?
In that case, as far as I know, its not possible with the native commands. (it could be possible if you had a program that showed a spinner while executing the operation that take long time)
And it looks like the echo don't support ansi escape sequences (in the old days you had to have ansi.sys loaded, don't know if that still exists) so you can't use ansi to control the cursor.
The spinner CAN be done in batch script, you just need some variables:
#echo off
:spinner
set mSpinner=%mSpinner%.
if %mSpinner%'==..............................' set mSpinner=.
cls
echo %mSpinner%
rem Check if the process has finished via WMIC and/or tasklist.
goto spinner
:exit
For the BAT itself to detect a process running/exits. You can do that via the WMI command-line interface or the tasklist command of which I have limited knowledge.
If it were back in the DOS days you could even does that without clearing the screen... short of using some combination of escape characters. I don't know if it's still possible on Vista/XP.
If you mean within a Windows batch script, you can't do it natively. The echo statement used to print to the console will always print a newline, and you can't move the cursor.
It's a bit of a hack, but you can do this with a combination of VBScript and batch script.
This VBScript will print a backspace, then it's argument:
WScript.StdOut.Write(chr(8) & WScript.Arguments(0))
Put this in a file, vbsEcho.vbs, then call this script from your batch script. The following batch script will keep displaying the spinner until you press CTRL-C:
#echo off
:LOOP
cscript //nologo vbsEcho.vbs "\"
cscript //nologo vbsEcho.vbs "|"
cscript //nologo vbsEcho.vbs "/"
cscript //nologo vbsEcho.vbs "-"
goto :LOOP
EDIT: Using some of the ideas from aphoria's answer, this script will start the Windows calculator, and display a spinner until the calculator closes:
#ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION
SET COUNT=1
START CALC
cscript //nologo vbsEcho.vbs "Calculating: \"
:LOOP
IF !COUNT! EQU 1 cscript //nologo vbsEcho.vbs "|"
IF !COUNT! EQU 2 cscript //nologo vbsEcho.vbs "/"
IF !COUNT! EQU 3 cscript //nologo vbsEcho.vbs "-"
IF !COUNT! EQU 4 (
cscript //nologo vbsEcho.vbs "\"
set COUNT=1
) else (
set /a COUNT+=1
)
pslist CALC >nul 2>&1
if %ERRORLEVEL% EQU 1 goto :end
goto :LOOP
:END
cscript //nologo vbsEcho.vbs ". Done."
paxdiablos has an amazing answer, but having to echo your commands into a payload file is annoying. It's hard to read and hard to debug. I took his code and modified it a bit for my own use:
#echo off

You can use a counter that prints a different character from a given set (like "\|/-") and you change the character according to like "counter modulo 4". Anyway, you don't say in which language you're working in so it is a bit difficult to be more precise.
EDIT: now that we know in which environment you're playing in, I'd say that the BAT/CMD language is not really up to the task... I'd recommend any scripting language, Ruby being my favorite.
I find the easiest way is to update the title - that way you don't have to do a CLS all the time.
The reason for the two lines of ping -n, is that it's quicker for ping to do a double ping of a second each, versus a single ping of two seconds.
Also, for those who don't know, a :: is the same as a REM, except that the comments are ignored at the beginning of the parser (I think this is the right word) instead of at the end. Simply put, that line is ignored.

This routine examines the output of tasklist for a process you START from cmd.
Pass it the name of the exe as a parameter e.g.
call :spinner calc.exe
It reports
Elapsed: 001 seconds
and increments seconds until the exe process terminates.
The Elapsed 001 seconds message is overwritten each second by ECHO.exe -n \r
which echos a cr without a line feed.
Echo.exe is available at
