I tried to use the tasklist command in cmd but it was not listed in there.
I also notice that the process is a little indented in task manager together with another process called wowexec.exe.
Any way to get the PID of the process? For reasons of hex editing.
wmic is nice for running sql-like queries to get the information you need. Replace wowexec in the following example with something resembling the task name of your VB3 process.
for /f "tokens=2 delims==" %%I in ('wmic process where "name like '%%wowexec%%'" get processid /format:list') do set "PID=%%I"
Something like that is what you would put in a batch script.
If you're just running this from a cmd console, use %I instead of %%I, and do #echo %I instead of do set etc.
for /f "tokens=2 delims==" %I in ('wmic process where "name like '%%wowexec%%'" get processid /format:list') do #echo %I
Note: The double percents around wowexec signify literal percent symbols, a SQL syntax wildcard character. wowexec is not a variable, but a literal string.

I try to set a batch variable to an output of another command. In Linux/Unix you can simply use backticks, e.g. (in csh)
set MY_VAR = `tail /etc/passwd`
Is there something similar available in windows batch?
Actually I found already something but it is not fully working:
d:\>for /F "skip=1" %n in ('wmic OS Get CurrentTimeZone') do set TimeZone=%n
d:\>set TimeZone=120
:\>set TimeZone=
d:\>
The problem is the wmic commands returns several lines, otherwise it would work fine. The first I know to skip, however I did not manage to skip the second empty line. I tried with IF but no success.
yes - the output of wmic is a bit ugly to handle.
Use a trick: search for a number in the ouput (findstr "[0-9] will only return lines, that contain a number):
for /F %n in ('wmic OS Get CurrentTimeZone ^|findstr "[0-9]"') do set TimeZone=%n
echo Timezone is %TimeZone%.
(for use in a batchfile use %%n instead of %n)
Another way is:
for /F %n in ('wmic OS Get CurrentTimeZone') do if not defined TimeZone set TimeZone=%n
EDIT:
I prefer the first version, as findstr (or find) converts the wmic-line-endings, so the second for mentioned by MC ND is not neccessary.
I suggest following batch code:
#echo off
for /F "skip=1" %%I in ('%SystemRoot%\System32\wbem\wmic.exe OS Get CurrentTimeZone') do (
set "TimeZone=%%I"
goto BelowLoop
)
:BelowLoop
echo Time zone difference is: %TimeZone%
The FOR loop is exited with command GOTO after the value of interest is assigned to environment variable TimeZone.
The entire FOR loop can be optimized to a single command line:
#echo off
for /F "skip=1" %%I in ('%SystemRoot%\System32\wbem\wmic.exe OS Get CurrentTimeZone') do set "TimeZone=%%I" & goto BelowLoop
:BelowLoop
echo Time zone difference is: %TimeZone%
Exiting the FOR loop after having the value of interest avoids the problem with wrong parsing of Unicode (UTF-16 Little Endian) encoded output of WMIC by FOR which otherwise would result in deleting the environment variable TimeZone. For details on wrong parsing of Unicode output by FOR see answer on How to correct variable overwriting misbehavior when parsing output?
for /f "tokens=2 delims==" %a in ('wmic OS get CurrentTimeZone /value') do set "timeZone=%a"
(to use in a batch file, remember to double the percent signs)
The added /value in wmic changes its output to key=value format. The delims clause in for command indicates a = as a separator. The tokens clause ask to retrieve only the second token/field in the line. As the only line with two tokens is the line with the required data, only this line is processed.
BUT, wmic output includes an aditional carriage return at the end of its output, that needs to be removed from the variable. An aditional for command can be used. The resulting command will be
for /f "tokens=2 delims==" %a in ('wmic OS get CurrentTimeZone /value') do for /f %b in ("%a") do set "timeZone=%b"
Or, for a batch file
for /f "tokens=2 delims==" %%a in (
'wmic OS get CurrentTimeZone /value'
) do for /f %%b in ("%%a") do set "timeZone=%%b"
echo %timeZone%
I have this really nice line in my batch file that tells me how many lines are in a file:
find /v /c "" C:\Users\c1921\mypath\myfolder\!$Unit!.txt
This is nice and gives me 31 for the particular file I'm working with. My problem is the file looks something like this:
Microsoft (R) Windows Script Host Version 5.8
Copyright (C) Microsoft Corporation. All rights reserved.
my_handled
219278
check
219276
control

I want to be able to skip the first three lines entirely and then save the first value and then use the second value in my next command etc.
How do I save the number (e.g. 31) into a variable in my batch file?
On a hunch I tried setting a variable like so but it wasn't effective:
set "$testVar="""
echo !$testVar!
This command allows you to "save the number (e.g. 31) into a variable in my batch file":
for /F %%a in ('find /v /c "" ^< C:\Users\c1921\mypath\myfolder\!$Unit!.txt') do set numLines=%%a
This command allows you "to skip the first three lines entirely" and process the rest:
for /F "skip=3 delims=" %%a in (C:\Users\c1921\mypath\myfolder\!$Unit!.txt) do echo Processing: "%%a"
However, in my opinion this problem could be entirely avoided if the three first lines in the text file are supressed from the very beginning. I think this file is generated via a VBScript of JScript program that is executed this way:
cscript progname.vbs > C:\Users\c1921\mypath\myfolder\!$Unit!.txt
The first three lines in the text file may be avoided adding //nologo switch this way:
cscript //nologo progname.vbs > C:\Users\c1921\mypath\myfolder\!$Unit!.txt
#ECHO OFF
SETLOCAL
SET /a count=3
SET "first="
FOR /f "skip=3delims=" %%a IN (q25089468.txt) DO (
IF DEFINED first (CALL :show %%a) ELSE (SET "first=%%a")
)
ECHO count=%count%
GOTO :EOF
:show
ECHO first=%first% second=%1
SET /a count+=2
SET "first="
GOTO :eof
I used a file named q25089468.txt containing your data for my testing.
You appear to be asking two entirely different things - how to count the lines and how to skip the first 3, then deliver each succeeding pair to another process.
I would like to run a script where I can get the windows Name and version of the system of all computers running in the company, put it in a text fil. Then make a system variable out of my windows name . I know what to run but where I am running into an issue is a place holder. so here is my code:
:OS_NAME
Set OS_NAME= systeminfo | find "OS Name"
:OS_Ver
Set OS_Version= systeminfo | findstr /B /C:"OS Version"
systeminfo | findstr /B /C:"OS Name" /C:"OS Version" /c:"BIOS Version" | >> G:\Directory\%Computername%
:OS_Arch
IF exist "%programfiles(x86)% (SET OS_ARCH=X64)
Else (SET OS_ARCH=X86)
:Win_7
systeminfo | find "Microsoft Windows 7" > nul
if %ERRORLEVEL% == 0 (
goto ver_7)
:Ver_7
Set Win7= systeminfo | find "Microsoft Windows 7"
Echo %computername% is running %WIN7% in %OS_ARCH% Environment >> G:\Directory\Win7Comps.txt
So basically I would like a place holder for the results of Systeminfo which i can refer to and parse it my SET command when I am making my system variables.
Thanks, any help would be appreaciated.
Not exactly sure what you're looking for, but the biggest problem I see is that systeminfo takes forever to run and returns much more information than you're looking for. You'd be better off capturing wmi queries using wmic. This is basically a rewrite of your example script, just using wmic rather than systeminfo. It should be much, much faster.
#echo off
setlocal
set prefix=G:\Directory
for /f "usebackq tokens=1,2 delims==|" %%I in (`wmic os get name^,version /format:list`) do 2>NUL set "%%I=%%J"
for /f "tokens=2 delims==" %%I in ('wmic bios get version /format:list') do set "bios=%%I"
for /f "tokens=2 delims==" %%I in ('wmic computersystem get model /format:list') do set "model=%%I"
>>"%prefix%\%COMPUTERNAME%" echo OS Name: %name%
>>"%prefix%\%COMPUTERNAME%" echo OS Version: %version%
>>"%prefix%\%COMPUTERNAME%" echo PC Model: %model%
>>"%prefix%\%COMPUTERNAME%" echo BIOS Version: %bios%
if defined PROGRAMFILES(x86) (set arch=X64) else set arch=X86
if "%name%" neq "%name:Windows 8=%" (
set out=%prefix%\Win8Comps.txt
) else if "%name%" neq "%name:Windows 7=%" (
set out=%prefix%\Win7Comps.txt
) else if "%name%" neq "%name:Windows Vista=%" (
set out=%prefix%\WinVistaComps.txt
) else if "%name%" neq "%name:Windows XP=%" (
set out=%prefix%\WinXPComps.txt
)
>>"%out%" echo %COMPUTERNAME% is running %name% in %arch% environment
Type wmic /? for more info, and try wmic computersystem get /? or similar to see a list of items that can be queried under each class.
wmic is the Swiss Army knife of Windows. Fun fact: you can even use wmic to generate a web page table of installed software on a remote system.
You are giving batch a little too much credit. If you ran echo %OS_NAME% it would literally echo systeminfo | find "OS Name". Variables in batch will always just expand, it won't process any further. This will also more than likely try to run find "OS Name" when you try to set the variable as the | is not escaped nor enclosed in double quotes.
If you want to set the output of a command to a value you have to capture it in a for statement like this:
for /f "tokens=2 delims=:" %%a in ('systeminfo ^| find "OS Name"') do set OS_Name=%%a
Then remove the leading spaces like this: (there is probably a better way to do this)
for /f "tokens=* delims= " %%a in ("%OS_Name%") do set OS_Name=%%a
A few things to note here. 1.) "tokens=2 delims=:" is setting the delimiter to : and it is selecting the second section only, which will pull only the part you want. 2.) the | is escaped with a ^, this needs to be done in for loops or anything after that will attempt to execute as seperate commands. 3.) "tokens=* delims= " The token here is * which is all tokens.
A few other problems I found.
systeminfo | findstr /B /C:"OS Name" /C:"OS Version" /c:"BIOS Version" | >> G:\Directory\%Computername%
This has an extra | character at the end.
IF exist "%programfiles(x86)% (SET OS_ARCH=X64)
Else (SET OS_ARCH=X86)
Two problems here, you didn't finish the double quote around the path, and else has to be on the same line as the ending parentheses of the if statement, like this:
IF exist "%programfiles(x86)% (SET OS_ARCH=X64
) Else (SET OS_ARCH=X86)
Otherwise it tries to process else as it's own command
This is the new Script and it Still Doesn't Work
I Get The syntax of the command is incorrect.
on FOR /F "USEBACKQ tokens=*" %%A IN (TYPE "C:\Windows\System32\tasks\at!num! ^| FIND "Command") DO (
SETLOCAL ENABLEDELAYEDEXPANSION
set num=1
:START
IF NOT EXIST "C:\Windows\System32\tasks\at%num%" (GOTO:EOF)
FOR /F "USEBACKQ tokens=*" %%A IN (`TYPE "C:\Windows\System32\tasks\at!num! ^| FIND "Command"`) DO (
set var=%%A
ECHO %var%
SET /a num=%num%+1
PAUSE
)
GOTO:START
To understand your code, I'm going to break it down into logic first then try to solve it. Let me know if I miss a detail...
Set num var to 0
Begin :Loop
set num var to its current value ::NOT NEEDED - You've specified this prior to the GOTO
increment num var by +1
if myfolder\at* file exists then read at%num% and find a string then output that line to %tmp%\1.txt ::Need quotations on file location.
set F var to the line stored in %tmp%\1.txt
set F="%%F: =%%" ::Please explain what you are trying to do with this command.
set F to start on 10th character and remove the last 11 characters from the line.
echo the variable
If it doesn't exist, exit, but if it does return to :Loop
You should tell us what you are attempting. If it is as simple as saving a variable from a text file output, set F=<file.txt will work. If it didn't, then something happened prior to that command. Still... what is set F="%%F: =%%"?
Unless you are using a FOR loop variable, there is no need to use %% on each end of the variable.
If this were a FOR loop, it would look like this:
SETLOCAL ENABLEDELAYEDEXPANSION
set num=1
:START
IF NOT EXIST "myFolder\at%num%.txt" (GOTO:EOF)
FOR /F "USEBACKQ tokens=*" %%A IN (`TYPE "myFolder\at%num%.txt" ^| FIND /i "string"`) DO (
PAUSE
SET var=%%A
ECHO !var!
PAUSE
SET var=!var: =!
ECHO !var!
PAUSE
SET var=!var:~10,-11!
ECHO !var!
PAUSE
SET /a num=!num!+1
ECHO !num!
PAUSE
)
GOTO:START
One good practice to check if commands are working, such as SET, insert an ECHO on the variable and a PAUSE right after each time you believe the variable should be changed. This will track what has changed on the variable so you can see if your command was correct and the changes were made.
I'd suggest using Batch's inbuilt function for loops, see here.
Conditionally perform a command for a range of numbers
Syntax
FOR /L %%parameter IN (start,step,end) DO command
Or maybe iterating over files in a folder would be better for what you are trying to do?
Loop through files (Recurse subfolders)
Syntax
FOR /R [[drive:]path] %%parameter IN (set) DO command
Or iterating over file contents?
Loop command: against a set of files - conditionally perform
a command against each item.
Syntax
FOR /F ["options"] %%parameter IN (filenameset) DO command
FOR /F ["options"] %%parameter IN ("Text string to process") DO command
This site has plenty of examples here which should point you in the right direction.
There are a few issues with your code, I've amended as follows to get the variable populated with the contents of the temp file.
set num=0
:Loop
set /a num=%num%+1
if exist "myFolder\at*" (
TYPE "myFolder\at%num%" | FINDSTR "\<Command\>" > "%temp%\1.txt"
set /P F=<"%TEMP%\1.txt"
Echo %F%
Pause
)
I don't know if this is the problem, but have you tried enabling:
setlocal enabledelayedexpansion
Then, inside the loop (or the IF(...)), you use !foo! to signify environment variables instead of %foo%.
See setlocal /? and set /? for more information.
Consider the following result from a hypothetical reg query:
..>reg query HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\MediaPlayer /v "I
nstallation Directory"
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\MediaPlayer
Installation Directory REG_EXPAND_SZ %ProgramFiles%\Windows Media Play
er
How do I grep the output so that I can assign the actual value of the setting (%ProgramFiles%\...) into a variable (or temp file)?
example for batch files:
#FOR /F "tokens=2* " %%A IN ('reg query HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\MediaPlayer /v "Installation Directory"') DO #SET PARAM=%%B
If you want to use it directly in console - use single percent sign to denote variables (i.e. %A and %B)
