For cleaning up Ubuntu 12.10 , you can use GUI applications like ubuntu tweak and/or bleachbit and with baobab to check disk space but I prefer to use the terminal.
Here are the commands That I use to save space and clean up all ubuntu 12.10 versions ( Ubuntu, Lubuntu, Xubuntu … )
Cleaning up Ubuntu using the terminal
Let’s start by checking the occupation of disk space you can use the command
df -a
then check the size of the main folders
Remove unnecessary libraries and packages:
To delete all package dependencies removed
delete the files (.deb) of the packages that are no longer installed in the system;
The following command is really interesting, because it allows the removal even of the configuration files. This can be useful when you want to reinstall applications from scratch.
clean is much more radical than autoclean. It removes any files .deb from the apt cache, including those relating to the packages currently installed. This command allow a good a good recovery of disk space counterpart is that if you reinstall a package it have to be downloaded. (1.2 GB recovered)
##r remove from the cache (/ var / cache / apt) any package, except for the lock files
we can tie together the commands with:
( I recovered 1.2 GB )
Now, check and resolve any errors or broken dependencies with:
Remove orphaned libraries
sudo apt-get remove --purge
or
sudo deborphan | xargs sudo apt-get -y remove --purge
and[/code]
To search and cleaning unused configurations
To search and cleaning folders and unused configurations files we can use :
to seek only
Remove Old Kernel
Each version of the kernel can occupy up to 150 MB. If you have downloaded the headers you get 250MB of space. Therefore becomes crucial periodically remove some of the older kernels.
Check the current kernel t
uname -r
View the installed kernels
Lists the headers installed
First remove the headers
using somethings like this
then remove any specific kernel that is no longer needed
( 0.6 GB recovered )
Remove unnecessary location data packets
To remove packages and languages that do not involve using the program localpurge.
.
In the window that appears after installation, select the languages you wish to protect.
Here you can select the languages that interest us.
for example we can check:
en
en_GB
en_US
en_GB.UTF-8
en_US.UTF-8
then
to reconfigure localpurge type
To save space: remove o shrink files
Let’s start by checking the folders size into home directory.
You can use the command
home directory
Let’s start by checking the folders size into home directory.
You can use the command
Files to check periodically to save space:
.xession-errors
One of the files that can grow up to tens of GB and that may need to check is the file:
/home/<myhome>/.xsession-errors
This file can be erased from time to time.
or to reduce it and keep last 200 lines of messages
A home directory that you can grow a lot is the directory /cache.
There there are the browsers cache so to clean up it I prefer to use browser commands.
The directory /home/my-home/tmp should be checked and emptied every so often.
directory /var
at the root level, from time to time, check the /var direcotry :
/var/log/
/var/tmp/…
/var/cache/…
to display the size of the /var
Alert. You should only delete files. Absolutely not delete the folders that contain them.
Large size file
May be useful to check if exist large size files everyware e for any users.
The command for 750MB size files may be like:
Services
When you start ubuntu like any S.O. are activated services that are not always necessary with the inevitable resource consumption. To check the services that are not strictly necessary on a terminal you can use sysv-rc-conf.
to install
to start with
Check or uncheck the options to set the start whether or not a service in a given runlevel (Less services are running more resources are available).
Free up RAM
To release the RAM could be useful

Manage archives
Install applications to manage archives of files compressed.
If one needs to use the various formats of compressed files evaluate the installation of the following packages.
Common Codecs
A few common codecs
Medibuntu
Perhaps you have to evaluate installation of non-free-codec. “Medibuntu (Multimedia, Entertainment & Distractions In Ubuntu) is a repository of packages that cannot be included into the Ubuntu distribution for legal reasons (copyright, license, patent, etc). ” You do not have permission to view the full content of this post.
