Ian, thanks for the reply, i check those flags that you say, but i cant found the way to do that logrotate compress in other directory, also i try with option oldir, oldir /tmp, but dosn't work, cause the dest dir, must be in the same device, i try do a link, but, no way. Do you have any idea to use the options that you said? to compress in other directory. Thanks.
P.S.: man page is my friend, the problem is that there isn't too much documentation about logrotate, specially, how to use correctly the options that it have. for example what you can do with prerotate, postrotate, etc..
