Loops - Deevez - Mar 12, 2015

Hello! So I was making a batch file last night, and had a quick thought.
Within the code for a loop
":label
code
code
code
goto label"
It is an infinite loops. But is there a way, or is it even possible to, make the loop happen a certain amount of times? Let's say I want to open three .txt's. I understand I can do "start notepad.exe" three times, but is it at all realistic to make a loop, that opens it once, happen three times, then end?

Thanks to anything helpful.

If I think I'm understanding you correctly, try this :)

Code 
@echo off

set/p ?=Enter the path of your textfile (C:\Hello.txt): 

set/p $=Enter how many times to open your textfile: 

For /L %%Q in (1,1,%$%) do start %?%

@exit

The previous code was with user inputs...but if you want to do it automatically use this one:

Code 
@echo off

set ?=C:\FilePath.txt

set $=How many times

For /L %%Q in (1,1,%$%) do start %?%

@exit

Let me know if you need me to explain anything 🤝

That's exactly what I'm looking for. Works perfectly. Thank you a bunch!

Hey no problem. Let me know if you need anything else 🎉

There is one thing I guess I could I ask. I've seen this done on a Console App. Now, I say "Console App" because I'm unsure if this was even in Batch or if it was made in VB or something. But this one program, upon the command on "stats", it told you all of your computer's stats, such as: CPU usage, RAM, and stuff like that. Do you by any chance know if that also is possible?

You might be looking for WMIC. Open command prompt and type in

Code 
wmic /?

That might help you get started.

I'll definitely try this out. Thanks a bunch!

Yeah agreed. This looks like a job for WMIC

* - Deevez - Mar 12, 2015

That helped a lot. Thanks a lot guys!

Another method of looping:

Code 
@echo off

set num=0

:label

set /a num+=1

echo Cats

echo are

echo best

echo %num%

if not %num% == 5 goto :label

pause

Also since nobody fully explained the wmic approach, the following commands are useful:

Code 
wmic baseboard list brief

wmic memorychip list brief

wmic memphysical list brief

wmic cpu list brief

wmic bios list brief

wmic diskdrive list brief

wmic logicaldisk list brief

More types of information are available. wmic /? will show you all the different things that are available. Basically all the CAPS names, that don't start with a forward slash (/).

Always here to explain things for people, Annikk. Haha, thanks!
