If you want it cleared, either 1) add "clear_tmp_enable=YES" to /etc/rc.conf, or 2) mount it on a memory file system. > 2/ how do I get information about tmp security? > I read a book a command 'sort', suggest not to use tmp > as temp directory It's insecure to use predictable names for temporary files if you put them where other users can create symlinks. Use the mktemp(3) function(s) to generate names, and you can avoid that problem. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Q: How do you make the gods laugh?
