Is there any way to remove the entries with same process names? - windows

Question

I'm trying to get the top 10 memory consuming processes and I am using the code provided as an answer in this Question. It works fine except that I don't want multiple entries of processes consuming different memory size and I was unable to sort it because it's memory consumption is different.
The code is:
#echo off
setlocal EnableDelayedExpansion
(for /F "skip=1 tokens=1,2" %%a in ('wmic process get name^,workingsetsize') do (
set "size= %%b"
echo !size:~-10!:%%a
)) > wmicc.txt
set i=0
for /F "skip=1 delims=" %%a in ('sort /R wmicc.txt') do (
echo %%a
set /A i+=1
if !i! equ 25 goto :end
)
:end
Can I get the output as:
96931840:iexplore.exe
82161664:explorer.exe
42319872:svchost.exe
31469568:dwm.exe
25690112:SearchIndexer.exe
17002496:taskhostex.exe
11007590:VCExpress.exe
8033894:avp.exe
7190528 :Skype.exe
7000416 :SkypeBrowserHost.exe
Instead of the output from existing code:
96931840:iexplore.exe
82161664:explorer.exe
42319872:svchost.exe
33656832:svchost.exe
31469568:dwm.exe
26943488:iexplore.exe
25690112:SearchIndexer.exe
18550784:svchost.exe
17002496:taskhostex.exe
16343040:svchost.exe

#echo off
setlocal EnableDelayedExpansion
set num=25
set /A skip=-num
for /F "skip=1 tokens=1,2" %%a in ('wmic process get name^,workingsetsize') do (
set "size= %%b"
set "size=!size:~-10!"
if not defined proc[%%a] (
set "proc[%%a]=!size!"
set "size[!size!:%%a]=1"
set /A skip+=1
) else if %%b gtr !proc[%%a]! (
set "size[!proc[%%a]!:%%a]="
set "proc[%%a]=!size!"
set "size[!size!:%%a]=1"
)
)
if %skip% lss 1 (set "skip=") else set "skip=skip=%skip%"
for /F "%skip% tokens=2 delims=[]" %%a in ('set size[') do echo %%a

Answer 2

#echo off
setlocal EnableDelayedExpansion
for /f "delims==" %%a in ('set # 2^>nul') do set "%%a="
(for /F "skip=1 tokens=1,2" %%a in ('wmic process get name^,workingsetsize') do (
set "size= %%b"
echo !size:~-10!:%%a
)) > wmicc.txt
set i=0
for /F "skip=1 delims=" %%a in ('sort /R wmicc.txt') do (
for /f "tokens=1*" %%p in ("%%a") do (
rem the following line doesn't work
rem if not defined "#%%q"
rem the preceding line doesn't work
SET "flag="
FOR /f "tokens=1*delims==" %%v IN ('set #%%q 2^>nul') DO IF /i "%%v"=="#%%q" SET "flag=Y"
IF NOT DEFINED flag (
set "#%%q=Y"
echo %%a
set /A i+=1
if !i! equ 25 goto :end
)
)
)
:end
This tokenises the entire line as read into %%p,q so %%q contains the process-name. It then checks whether the variable #processname is defined and if it is not, generates the report-line and sets #processname so that the first mention will be the last as that variable is now defined.
The first line is designed to set any existing #* variables to empty; the 2^>nul suppresses error messages should no #* variables exist and the caret escapes the > to tell cmd that the > is part of the command to be executed, not of the for.

It appears that the if defined "varname" that I invented doesn't actually work, although it appeared to work when I tested it. I've replaced that instruction with code that does work and marked it out.
