move file...but make sure no process is writing to it

[aswolff]

Hi.

I need to create a sweeper program that moves files from one unix directory to another and changes the extension. But I need to ensure that the file is not being written to at the time I move it or I will corrupt the file. Any suggestions?

Plan B: Just look at the modified date and only pick up files older then 10 minutes or something...but I am trying to see if there are better ways than this.

Any feedback is appreciated.

You could use the "lsof" command, which lists open files.

That's a shell command.
