Looping in DOS batch scripts

Hey,

a question to all the DOS batch experts.

I'd like to create a looping batch script that does slightly different things (but effectively the same), but to different targets.
I know how to do it in rexx, but i'm not firm enough to pull it off in .bat.

Here's what i like to achieve (i have the loop figured out, but i don't know how to set up the target(s), so that the loop will read them one by one.


Any help appreciated, thank you very much

MSDOS .bat files complete different, You might consider writing a py or ruby or vbs script, they are easier to write.

This is AmigaDOS

@Raziel

AmigaDOS don’t use #?.bat as extension, only protection bit S for script.

Anyway, if you have directory with sub directories.
You can use LIST command with LFORMAT, to generate a new script. for etch directory.

Anyway this can be easier in AREXX, way better for strings.

@LiveForIt

Actually i've got it all figured out, the only thing missing is a way to give a variable with differing entries to the loop.

I know there is .KEY, but is there something like .KEY.1(.2,.3 etc.)
That way i could simply enhance a counter (e.g. i=i+1) during the loop and simply ask for .KEY.i.

...

I know arexx is far better suited for this (that's why most of the work is done by an arexx script already).
The problem is, that i need to be IN the directory when starting the arexx script, because arexx will only act on the directory it is started in, so i have to copy the rexx script to either directory and that is what i'd like to do in a batch loop.

Right now i mirrored four commands in the batch one after the other, each altering only in the path where the rexx script is copied to and started in.

There has to be a smarter way...

Hi,

ForEach command would fit what you want to do maybe?

@Petrol

Good call, exactly what i was looking for

Thanks a lot

Quote:This sounds to me like a misunderstanding - although I am not quite sure what you're actually trying to do, once you know where to do it.

You can always build a path in a string variable, even an absolute one, or a relative one starting with one or more '/' for that matter, and use that string variable to "address command 'cd ' || pathvar" or something, i.e. effectively set the current dir of your running script's process somewhere else.

Normally it's good practice to save your current dir first, so you can restore it at the end of the script.

Best regards,

I need to make a note of this, might actually save me the batch script...then again, it's down to some lines with foreach

But thank you for the suggestion, Niels

I once made a file size based counter ;) I don't know if there would be other way, but if you don't have the ForEach command (on OS3, for example), then you could hack it like this (modified it to do what you asked) :P



And that would output:

Thank you, worth a peek
