i try to write a batch file which gives me the free physical memory. This batch should write every X seconds a timestamp and the following command in a text file:
wmic OS get FreePhysicalMemory
My batch file looks like this:
:loop
(
@echo %time% %date%
wmic OS get FreePhysicalMemory /Value
)>testMEMORY.txt
timeout /t 10
goto loop
This is the output:
13:54:54,76 04.11.2019
F r e e P h y s i c a l M e m o r y = 7 2 0 6 6 4 8
I don't get it, why i have a lot of new lines and after each character a space. Can anybody help me please?
The output of WMIC is unicode !
The trailing <CR> can be removed by passing the value through another FOR /F loop.
This also removes the phantom "blank" line (actually a <CR>)
@echo off
If Exist testMEMORY.txt Del testMEMORY.txt
:loop
(
@echo %time% %date%
for /f "skip=1 delims=" %%a in ('wmic OS get FreePhysicalMemory /Value') do (
for /f "delims=" %%b in ("%%a") do (
echo %%b
)
)
)>>testMEMORY.txt
timeout /t 10 /nobreak>nul
goto loop
So, i got as result in testMEMORY.txt something like that :
15:32:19.02 04/11/2019 FreePhysicalMemory=528592 15:32:29.19 04/11/2019 FreePhysicalMemory=530804 15:32:39.14 04/11/2019 FreePhysicalMemory=531156 15:32:49.21 04/11/2019 FreePhysicalMemory=530968 15:32:59.16 04/11/2019 FreePhysicalMemory=531936 15:33:09.23 04/11/2019 FreePhysicalMemory=530376 15:33:19.18 04/11/2019 FreePhysicalMemory=524980 15:33:29.16 04/11/2019 FreePhysicalMemory=521816 15:33:39.21 04/11/2019 FreePhysicalMemory=465820 15:33:49.17 04/11/2019 FreePhysicalMemory=461312 15:33:59.17 04/11/2019 FreePhysicalMemory=385172 15:34:14.21 04/11/2019 FreePhysicalMemory=529800 15:34:24.13 04/11/2019 FreePhysicalMemory=541064
