How to Deternine file status

lohrpr · 07-27-2006, 11:41 AM

All,

I would consider myself a mid-linux user. I am an Oracle DBA and have done a few installs of Oracle on linux so I am familiar with some scripting. I need a script that will move files from a directory to another directory. The catch is the first directory is a directory that many users will FTP files to, after they FTP the file, a CRON job will process the files. Some of these files will be large and may take some time to transport. I have to process the files within 2 min after the file transfer completes. I have scripts that can move files based on date or even time. My issue is if I use “ls” to find out if there are any files in the directory it will show me files that have not yet completed the file transport. Basically, I need a script that will look at a folder and determine which files have completed the file transport and not the ones that are in the middle of transport.

Also I will need to move this to a solaris box in production so I need a command that will work on both.

Any help would be appreciated,

Thanks

I'm not sure about that, but shouldn't lsof do the trick?

Please do not post the same thread in more than one forum. Picking the most relevant forum and posting it once there makes it easier for other members to help you and keeps the discussion all in one place.

By "process the file" do you simply mean "move it to another directory?" If so, you could use "ln" and "rm" cronjobs.

The following assumes you don't care if the in-transit file appears in the destination while it's still being transferred, your source files are uniquely named, the source and destination directories are on the same filesystem, and that only plain files exist in the source directory. These are a big assumptions since you didn't really tell us any details of your task. This example is for the simplest scenerio I can imagine, but maybe we've gotten lucky here and you really are dealing with this simple case!

cronjob that repeats every one minute:

Code:

ln /path/to/source/dir/* /path/to/destination/dir/ >/dev/null 2>&1

cronjob that repeats as needed for cleanup of files in source (this example deletes files over a day old):

Code:

find /path/to/source/dir -type f -mtime +1 -print | xargs rm -f >/dev/null 2>&1

The normal thing to do is that when a mod does the "please do not post....." thing, stop responding.
