How to make batch files in Windows 7

I’m afraid that PowerShell vanishes no matter where I start it from. If I type it into the search bar on the start menu and press “enter,” the window appears and vanishes. If I type in powershell but don’t press enter I get 3 choices, powershell, ISE, and modules. Clicking on any of these three produces the same results.

type in “powershell”, don’t press enter
Right-click powershell from the choices and click ‘Run as administrator’ from the sub-menu.

FYI “echo > file” on Windows does not produce an empty file. The file will contain a line of text saying “echo is on” or “echo is off”.

Good point. This works instead:

for /l %a in (0, 1, 9) do for /l %b in (0, 1, 9) do for /l %c in (0, 1, 9) do type nul > filename%a%b%c.txt
