Hi there, on a Linux machine running Python 2.3.5. I want to create a file 'newfile' in a directory '/tmp' only if there is no file 'transfer.lock' in '/temp'. A cronjob creates a file 'transfer.lock' in '/temp' directory every 15 minutes while the cronjob is doing something. This job takes around 30 seconds. During these 30 seconds the 'transfer.lock' file is present in the '/temp' directory and I must not create 'newfile'. After the cronjob has been finished, the 'transfer.lock' file is deleted from '/temp' and I can create 'newfile'. How can I use a timer that waits e.g. 10 seconds if 'transfer.lock' is present and then checks again if 'transfer.lock' is still there?
I want to do something like this: import os if 'transfer.lock' in os.listdir('/temp'): # ...wait 10 seconds and then check again if # 'transfer.lock' is in os.listdir('/temp') else: # create 'newfile' Nico -- http://mail.python.org/mailman/listinfo/python-list
