Batch Programs Thread.

[Moderator]

That's just perfect...why are we still even entertaining this ? ?

hey guys new here, i wanted to pick your brains as im struggling to find an answer to what im looking for!

basically ive got some software that my dad had wrote by a programmer it ships with hardware he sells, (vehicle diagnostics etc) im editting his installer that runs from a usb key which also acts as a security dongle so it has to be by dongle and i cant switch to CD or DVD , it uses a batch file which i will eventually convert into a .exe as long as the code all works

the batch file works great, it all installs fine and goes thru spot on and everything is fine, the only thing i cant get to grips with is i would like to delete some driver files from the usb once it has installed once this is so people who try to steal the software once its been installed once will be missing crucial drivers(long story but go with me on this one for now!) my problem is when you put in a usb key, its normally a different drive letter everytime, so i cant link to a static drive letter to delete from  ie; C:/ D:/ etc etc, ive tried using CD\ (to go to top directory) and then DEL for delete but i cant seem to get it to work, im not overly experienced with ms dos, but ive coded in other languages so i understand the fundamentals just not the syntax,

heres what i have:

@ECHO Y
CD\
del folder/file1.dll
del folder/file2.dll
del folder/file3.dll
del folder/file4.dll

i know its probably rubbish but hey ive tried for days on this before asking for help! thanks

I expect you know about the replaceable parameters %1 to %9. Well, there is another one: %0 (that's a zero after the percent symbol). This is a special variable: it contains the batch script's identity.

If you have a batch script called Hello.bat and it contains this line:

Code: [Select]

echo This script is %0
When it runs, on the screen will be echoed:

Code: [Select]

This script is Hello.bat
You can use the same standard variable modifiers with the tilde ~ symbol that work with %1 to %9 and also with FOR variables.

Code: [Select]

    %~I         - expands %I removing any surrounding quotes (")
    %~fI        - expands %I to a fully qualified path name
    %~dI        - expands %I to a drive letter only
    %~pI        - expands %I to a path only
    %~nI        - expands %I to a file name only
    %~xI        - expands %I to a file extension only
    %~sI        - expanded path contains short names only
    %~aI        - expands %I to file attributes of file
    %~tI        - expands %I to date/time of file
    %~zI        - expands %I to size of file
The I is just a letter used for explanation purposes in the documentation for the FOR command.

So in a batch script %~d0 will expand to the drive letter of the drive that the script is on. %~d0:\ is the root directory of that drive. 

thanks this makes sense, but defo aches my brain haha!

Not quite sure what that means so i'll have to say i agree...

Defo. a shortening of definitely for use when responding in agreement ...

...the defo program runs on an Apple OS, not MS DOS.

%~d0:\ is the root directory of that drive.

Correction: %~d0\ is the root directory of the drive on which the batch file is located. (The colon is included automatically)
