Lock processed files

[offspring86]

Hello,
I'have a PHP script (which runs regulary), which moves data from one FTP to another. Files are to large, so when the script is activated again, it can start processing files which are listed in script activated before.

So have can I lock these files not to be processed by another script.

Thanks for help in advance

You could use [man]flock/man, but you would need to add it to any script which might access those files.

you could add a check at the start of the script to make sure its not already running, so only one copy at a time runs.

I have got a very simple solution 🙂

At the begining script checks for a directory "lock", if it exists, false is returned. Otherwise script makes a directory "lock" and deletes it after processing.

Thanks you all for replies.
