Hi everyone, There is a way to make files being automatically deleted some time after they have been created? I know that, with some scripting wizardry i could achieve this, but i wanna know if samba has this kind of feature. I have a temp folder that users insist in use like a backup folder, so i want to files to be deleted 24 hours after they have been created. I cannot just delete everything at midnight because this folder is used in full time, so if a user create a file at 23h59, it would be deleted a minute later. Sorry for my poor english and tks in advance. -- Leonardo Carneiro
You could write something to check file create times and delete files older than 36 hours, and run if from cron several times per day. I'd suggest # find, but it doesn't have the granularity you are looking for, you could run it at 00:01 and remove files there where 2 days old. I did somethign similar on a VMS system I was managing, worked well until some enterprising student found (I don't believe they wrote it themselves) a program to reset the time stamp on their files (which your users may start doing as well, perhaps using # touch). At which point I started looking for files with creation dates in the future... many users of the date reset program wheren't quite as smart as they thought they where.

Hi Brian, tks for your answer. I'm confident that my goal could be achieved through the use of some third-party tool, like a script or something like it, like you sugested. But what i really need to know is if there is some feature in samba that would allow me to do just that. But tks anyway for your answer.

It is probably already part of your distribution, but if not, you can get it from https://fedorahosted.org/tmpwatch/ Regards, roel
You could write a bash script like this: #!/bin/bash find /some/temp/dir/ -name "*" -atime 1 -delete Where atime* indictates file was modified 1 * 24 hours ago. (*There are loads of time based operators for find) See http://unixhelp.ed.ac.uk/CGI/man-cgi?find for the find man page. You may also want to use -P to never follow symbolic links. Then once the batch file is created, chmod it to something like 750, and make it a cron job to run every hour.
