windows - How to Use IF Exist condition -


i have batch script check status of task running task scheduler , status of batch file , status of network load balancer.

my question :-

step-1:- want check status of task(health.bat) running in task scheduler if enabled or in ready status jump , check step-2

step-2:- here need check status of network load balancer(nlb) if in converged state jump , exit or else run -->health.bat-->if there no error --> start nlb or else-->send mail error message

issue code:-

the code running call health.bat jumps start nlb though health.bat fails :- 

  @echo off setlocal enableextensions enabledelayedexpansion set itemail="mailid" /f "usebackq" %%i in (`hostname`) set host=%%i ::set host=%computername% set taskname1=health c: cd\ cd batch :: checking wscheck disabled schtasks.exe /query  /tn "%taskname1%" >checkts.txt 2>&1   findstr "running ready" checkts.txt if %errorlevel% neq 0 (  schtasks.exe /change /enable /tn "%taskname1%" >checkts.txt schtasks.exe /query  /tn "%taskname1%" >>checkts.txt wmailto %itemail% -s"the task health has been enabled on %host%." -tcheckts.txt ) :: checking if node stared nlb.exe query >checknlb.txt 2>&1 findstr /l /c:"converged" checknlb.txt if %errorlevel% neq 0 ( call wscheck.bat if exist findstr /l /c:"<--fail-->" health.txt (  wmailto %itemail% -s"down node %host% cannot started health failed." -thealthstatus.txt goto :exit ) else ( nlb.exe start >checknlb.txt timeout /t 10 nlb.exe query >>checknlb.txt wmailto %itemail% -s"the nlb has been started on %host%." -tchecknlb.txt ) )   :exit pause

--->health.bat<---

@echo off setlocal enableextensions enabledelayedexpansion rem set  set itemail= "mailid"  pushd "c:\health" || goto :eof      set "tries=2"     /l %%a in (1 1 %tries%) (       >health.txt (             call pcheck.cmd             tester.exe -s parse          )         echo tester returned errorlevel : !errorlevel!          if not errorlevel 1 (             wmailto %itemail% -s"up -  health monitoring." -thealth.txt"             goto :eof         )         if %%a equ %tries% (            wmailto %itemail% -s"down -  health monitoring." -thealth.txt          )     )

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
