How do I delete site log files automaticly on Ensim? And I have too many to go through and delete manually

you could create a cron job that runs A. a shell script that automaticly deletes B. A cron job that runs a perl program that deltes the files

I have no idea how to write that script there has to be one already made.. anyone know were to get one?

Go with a shell script. All it is, is a script that contains regular commands. Its like a windows autoexec(but with more options) for an example, make a file, test.sh, in it just put

pwd


Then make sure it has executable permissions, and do ./test.sh and see what happens, then take it from there. Search the web, you can get more help on it. I think it is important that you do this on your own.
