File access.log from server www has reached allowed size for file
system.
1. How to set file size to 0 using shell command.

cat /dev/null > access.log

2. Write a script in whatever language ( perl, bash itp. ) checking
once a day size of the access.log file and in a circumstance that he
reached its maximum capacity ( eg 2 GB) he will set size of the file
