Re: Simple Log Rotate Problem

when you move the file, doesn't that delete it?

    *   The "move" function also takes two parameters: the current nam
+e and
        the intended name of the file to be moved. If the destination
        already exists and is a directory, and the source is not a
        directory, then the source file will be renamed into the direc
+tory
        specified by the destination.

        If possible, move() will simply rename the file. Otherwise, it
        copies the file to the new location and deletes the original. 
+If an
        error occurs during this copy-and-delete process, you may be l
+eft
        with a (possibly partial) copy of the file under the destinati
+on
        name.

        You may use the "mv" alias for this function in the same way t
+hat
        you may use the "cp" alias for "copy".

I prefer to cp/truncate instead of deleting. That way you do not have to worry about restarting the service that has the file open for logdumping. on commandline it looks like this: `rm logfile.5 mv logfile.4 logfile.5 mv logfile.3 logfile.4 mv logfile.2 logfile.3 mv logfile.1 logfile.2 cp logfile logfile.1 cat /dev/null > logfile` [download] its about the same thing in perl except you use File::Copy's copy and move and `open OUTFILE, ">logfile"; close OUTFILE;` to truncate -Waswas	[reply] [d/l] [select]
