Waiting for Parallel batch scripts or command lines

Question

I am finding it difficult to modify the script here to suit my requirements: https://stackoverflow.com/a/12665498/4683898

@echo off
setlocal
set \"lock=%temp         


        

Answer 1

just to offer an alternative way:

@ECHO off
start "MyCommand-%~n0" cmd.exe /c ping localhost
start "MyCommand-%~n0" cmd.exe /c ipconfig /all
start "MyCommand-%~n0" cmd.exe /c sysinfo
:loop
tasklist /fi "windowtitle eq MyCommand-%~n0"  | find "===" >nul && goto :loop
echo finished!

Edit for your comment. bunch is the number of commands running in parallel.

@ECHO off
setlocal enabledelayedexpansion
set bunch=3

for /f "delims=:" %%a in ('findstr /n /b "REM ==" %~f0') do set /a datastart=%%a+1
set count=0
for /f "skip=%datastart% usebackq delims=" %%a in ("%~f0") do (
  set /a "count=(count+1) %% %bunch%"
  echo starting: %%a
  start "MyCommand-%~n0" cmd.exe /c %%a
  if !count!==0 echo waiting & call :loop
)
echo waiting & call :loop
echo finished!
goto :eof

:loop
tasklist /fi "windowtitle eq MyCommand-%~n0"  | find "===" >nul && goto :loop
goto :eof

REM == START DATA ==
ping localhost
ipconfig /all
systeminfo
tasklist
echo hello
schtasks /query
wmic bios get /value
timeout 10

the first for just gets the line number where your commands are (start of DATA section)
