如何打开cmd.exe并执行命令？

Question

So I want to set the system volume to 25% through a batch file. I managed to open cmd.exe using:

start cmd

however when I add the command:

start cmd /k echo nircmd.exe setsysvolume 16384

it types it into the cmd window, but doesn't actually execute the command. It's hard to explain, but it's like the text is written before the command line interface actually begins taking commands. What results is:

nircmd.exe setsysvolume 16834
C:\Users\User\Desktop>

Any ideas what is going on?

Answer 1

echo nircmd.exe setsysvolume 1638 > foo.bat && start cmd /k foo.bat

You also can run it this way

echo nircmd.exe setsysvolume 1638 > foo.bat && start cmd /c foo.bat

so that the new command window closes when foo.bat has finished or just

echo nircmd.exe setsysvolume 1638 > foo.bat && foo.bat

to run foo.bat directly.
