Everyone tries to keep their servers and workstations up as long as possible. However, you do need to reboot your computer to check the file system thoroughly and to clear any cache or temporary files that are in a hung state.
Force your system to run fsck on your file systems during the next reboot. In order to do this, you need to create a file called “forcefsck” in your root “/” folder.
Open up Terminal and type :
sudo touch /forcefsck Hit the Enter key
sudo shutdown -r now Hit the Enter key
Be patient while your file system is checked.
Bleachbit was designed for Linux and Windows. This program frees up your hard drive space by removing ‘junk’ files and helps to get ride of cache, cookies, internet history, logs and temporary files. BleachBit cleans more than 70 applications.
Also see Avast! for Linux for virus protection. After holes were found in Linux that could have been years old, it is a good idea to make sure you are protected.
Want to find the top running processes in Ubuntu? Go to the Terminal and type Top. Top will refresh automatically.
