Ubuntu optimize, cleanup, defrag programs?

I used to use CCleaner in windows just to keep things running fast and smooth clean registry.

I cant find any such program for ubuntu. also...what about defraging?

 

Not necessary. Linux doesn't use a registry like Windows, which is what gets cluttered and broken in Windows.

Also, there are some defragging utilities in the software package manager if you do a search, but the ext3 filesystem doesn't get very cluttered. To be honest, NTFS doesn't have a big problem with this either, especially the new version in Vista. Defragging was really useful with FAT systems (previous to WinXP), but has lost some of its necessity lately.

 

You can use the command line to clean up old and unused packages that APT has accumulated:

sudo apt-get autoclean

You can also use a program called Deborphan to uninstall orphaned packages (packages that are no longer depended on for anything).

Lastly, Linux filesystems (ext3, primarily) do not fragment to the extent that Microsoft's NT filesystems do; as such, defragmenting is not necessary.

 

oh cool. thanks

 

In general, Linux systems are so much more streamlined than Windows ones. Why does Windows even use the registry anyway?

 

Linux fragments itself on purpose and stays that way...it leaves 'room' to insert new files here and there. Take a look at a linux 'driven' ntfs external harddrive and you can see how it lays everything out. IOW, no need to defrag linux file systems in general.
