How to loop through tasks in Windows cmd and only output task if it is NOT in a list?
I am trying to output unneeded tasks to the Windows command line. The end result should be that I basically kill all unneeded tasks with the click of a button. But to avoid any problems I am outputting the tasks names for now. I know there is other ways like disabling them on
regedit, but for now this is what I want.
The problem is I have been away from console usage for a long time and it has left me slightly confused. I have code below that outputs all running tasks, but it doesn't stop outputting the tasks in the
mylist array. I think the problem is my nested
for loop, but I don't know any other ways of passing the two arrays to one list so that I can check them. Any help would be greatly appreciated.
@echo off set mylist=csrss.exe, dwm.exe, System, smss.exe Rem<<List for /f "tokens=1" %%a in ('tasklist') do ( Rem<<This returns process name for %%b in ('%mylist%') do ( Rem<<b is MEANT to be each process in list if not %%a == %%b ( Rem<<If anything in tasklist is in mylist, don't include it echo %%a) Rem<<Output processes NOT in mylist. ) ) pause
that's much easier with the help of
@echo off set "mylist=csrss.exe dwm.exe System smss.exe" for /f "tokens=1" %%a in ('tasklist^|findstr /biv "%mylist%"') do echo %%a pause
- b = beginning of the line
- i = ignore capitalization (optional)
- v = exclude the given string(s)
whats the difference between: %%a and %variable% variables , files. If you need loop, then in most cases for has you covered. c# ile tarayıcıdan veri alıp veritabanına kaydetme Başlıklı sayfamız konusu itibarıyla inceleme yapabilirsiniz. ilginizi cekecek muhakkak birsey vardır.
What does the percent sign (% and %%) in a batch file argument , How do I see what processes are running in Windows?
Since task/image names might also contain SPACEs, I recommend not to use a SPACE-separated list of exclusions; instead I would put the items in a text file, one item per line, like this, for instance:
csrss.exe dwm.exe System smss.exe
@echo off set "_LIST=%~1" set "_TMPF=%TEMP%\%~n0_%RANDOM%.tmp" > "%_TMPF%" ( for /F delims^=^"^ eol^=^" %%P in (' tasklist /FO CSV /NH ') do @( echo(%%P ) ) findstr /VIXG:"%_LIST%" "%_TMPF%" del "%_TMPF%"
The list file can be specified as a command line argument here.
Or you could also avoid the temporary file and use this slightly more complex code instead:
@echo off set "_LIST=%~1" ( for /F delims^^^=^^^"^^^ eol^^^=^^^" %%P in (' tasklist /FO CSV /NH ') do @( echo(%%P^& rem/ ) ) | findstr /VIXG:"%_LIST%"
If you do want to embed the list items in the batch file, you could do it like in the following example:
@echo off set "_TMPF=%TEMP%\%~n0_%RANDOM%.tmp" > "%_TMPF%" ( for /F delims^=^"^ eol^=^" %%P in (' tasklist /FO CSV /NH ') do @( echo ::::%%P ) ) for /F "delims=: eol=:" %%Q in (' findstr /BC:"::::" "%~f0" ^| findstr /VIXG:/ "%_TMPF%" ') do ( echo(%%Q ) del "%_TMPF%" ::LIST ITEMS: ::::csrss.exe ::::dwm.exe ::::System ::::smss.exe

- There are not arrays in batch file! Also, I can't understand:
if not %%a == %%b.
tasklistwill give you 5 columns, each one is one token (if
exename is one word, but here
exeyou have provided are one word.). 1st column is the
image nameand second column is
PID. They won't be equal in NO ONE case.

- This can be called "array"?
- there are two main errors in your code: your 2nd

'(you don't want to execute a command, but process a list); Every line of
tasklistwill be shown at least three times (you have four strings in your list, each filename from
tasklistwill be at least different from three of them. The second one is a logical error, which needs code redesign.
- @double-beep, KieranBrown: this is not an array, but a list.
- What I actually don't like in this approach is that you can't specify list items with spaces, but that's already a flaw of the OP's concept; I'd probably put the given process names into a text file, one name per line and use
/Goption; of course
tokens=1needed to be changed then...
TASKLIST /NH /FO CSVwould allow spaces in name (but require mylist entries to be d'quoted) and also remove the header (+1)
