Script to count files in a folder

[umut.tabak@student.kuleuven.be]

Dear all,

We have a multi-platform application(Win dows-Linux). Linux part of our
application is writing some input and trigger files on the a shared
drive. What I want to do is to be able to count the occurence of these
trigger files.

lets say my file is

file.start

A batch file creates this file and deletes that file in the same loop.
This file is intended to start the reading of an input file. After it
is read batch file deletes this file automatically and on the next loop
it will be written and deleted again. With this script I have to count
the occurences of the file on this specific folder.

I did not have the time to think on it but maybe you can give me some
ideas on that. And btw, I am not an expert in scirpting. I am trying to
learn Python but this task is a little bit over my head.

Any help or thoughts are appreciated.

With best regards

[Fredrik Lundh]

what does "count" mean here?

do you want to check if the file is there, or how many times a file with
that name has been created ?

the former is easy (just use the os.path.isfile( ) function), the latter is not
really possible.

Yes I would like to check how many times that specific file is created.
so count is the number of times of creation.

As Fredrik said - not really possible, at least not with standard python.
For Linux, you might be lucky using the python LUFS module:

http://www.freenet.org.nz/python/lufs-python/

But you being a beginner, I guess that is a bit over your head. Trying to
change the behaviour of the batch skript, writing out the information you
need is the more reasonable approach.
