I'm surprised that base.txt is generated at all, I'd expect fix.pl to look for a file named base.gtx base.txt and complain when it doesn't find that. I think the following should work: with open(c:/scripts/perl/base.txt, w) as f: subprocess.check_call( [perl, c:/scripts/perl/fix.pl, c:/scripts/perl/base.gtx], stdout=f) ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

I'd just like to add a generally useless and pedantic comment about the habit of saying DOS prompt. The cmd shell is a Win32 console application, unlike DOS command.com. On 64-bit Windows there isn't even a virtual DOS machine (NTVDM) to run command.com. There, I feel better now. :) ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Yes, but the problem is that Windows now has so many command prompts (cscript, cmd, power shell etc) that the Windows prompt would be meaningless and the cmd prompt too awkward to say, so the DOS prompt is both traditional and sufficiently specific making it the most easily understandable of the likely terms. -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

DOS prompt is a common idiom, but it bears mentioning now and then that the OS is NT [1], not DOS. That's all; I know I'm being pedantic. Officially the Windows command-line shell is called the command prompt. I call it the shell [2] or command line. Unless someone says PowerShell or 4NT, I assume it's cmd.

If you are not doing any other processing Python is inefficient and overkill for this task. Unless you just want to learn how to use Popen I suppose... path=c:/scripts/perl/ subprocess.call(['perl','fix.pl','base.gtx base.txt',path]) Do you get any error messages on the console?
