批量文件在循环中运行Windows命令

Question

the following below code opens 10 command prompt windows. But I am trying to finish one command at a time and start the next in the same window. Can anyone please suggest changes?

echo off
SET /a i=0

:loop
IF %i%==10 GOTO END
echo This is iteration %i%. 
START cmd.exe /K "cd C:\bin\phantomjs-1.9.2-windows & phantomjs examples\loadspeed.js"
SET /a i=%i%+1
GOTO LOOP

:end
echo

Answer 1

Using your approach, you can use start /wait and cmd /c in combination to open ten windows one at a time. The /wait pauses the batch files execution until the new CMD window closes. /c tells the CMD window to close when it finishes processing the quoted commands.

START /wait cmd.exe /c "cd C:\bin\phantomjs-1.9.2-windows & phantomjs examples\loadspeed.js"

If you want to run the ten iterations in a single new window, then you need to change your command to something like this:

@echo off
start /wait cmd /c "@echo off&&for /L %%i in (1,1,10) do (echo Iteration: %%i&&ping -n 2 localhost)"

This opens a new CMD window and then executes the echo and ping statements 10 times, each time waiting until the prior set finishes before moving to the next iteration.

Answer 2

This should execute it 10 times, one after another.

@echo off
cd /d "C:\bin\phantomjs-1.9.2-windows"
for /L %%a in (1,1,10) do (
   echo This is iteration %%a
   start "" /w /b "phantomjs" "examples\loadspeed.js"
)
pause
