    I have seen some posts on Internet about the growing size of logs and how to delete them.Some logs grow so much that some people get low disk space warning.
    My question is:May I restrict the size of the logs,or do I have to clean logs from time to time(how to do safely).

    Unless you are extremely low on hard disk space then you are fine, assuming you let the installation set your partitions. If not how big did you set your /var partition?

    You can check your sizes by:
    cd /var/log
    sudo du -a -h

    your total will be at the bottom. Mine is a lowly 12MB :)

    You can also install Bleachbit from the repository to delete log files and other stuff from time to time.

    Ubuntu automatically installs logrotate which automatically rotates the logs. If you go into /var/log and see a bunch of *.tar.gz files, those are files that logrotate has "rotated" and then compressed for storage. If you have extra log files you have created you will manually need to write a logrotate script for them (it's easy). If you have not created your own logs, you are good to go. Nothing needs to be done.

    For more info you can read the manual:

    Code:
    man logrotate

    Under the web browser section, checking "passwords" will delete all passwords, "places" deletes bookmarks, "session restore' deletes ability to restore session after a crash.
    As far as the rest, I don't know. I use them with no ill effects, but I'm still a relative newbie.
