Ubuntu system spam tutorial

If you want to clean up your Ubuntu host, you can follow some simple steps below to remove all unwanted junk files.

Remove unnecessary software packages

This is also a built-in function, but this time we don't have to use the new Package Manager (Synaptic Package Manager), but to achieve the goal in the terminal.

Enter the following command in the terminal window:

Sudo apt-get autoclean

This activates the package clearing command. What this command does is to automatically clear the system cache when you install or upgrade the program. deb package (that is, clear the/var/cache/apt/archives Directory, but only clear outdated packages ). To run the clear command, type the following command in the terminal window:

Sudo apt-get clean

Then you can use the automatic remove command. This command is used to clear software packages installed by an uninstalled software in the system as dependencies. To use the automatic remove command, type the following command in the terminal window:

Sudo apt-get autoremove

Remove unnecessary local data

To achieve this, we need to install the localepurge software, which will automatically remove unnecessary local data (LCTT translation: various language translation ). This software is a simple script that recycles disk space from the space occupied by localization files and localization online manual (man pages) that are no longer needed. This software will be automatically activated when running any apt installation command.

Install localepurge in Ubuntu:

Sudo apt-get install localepurge

After installing any software through apt-get install, localepurge will remove all online manuals for translation files and translations that are not using the language set in your system.

If you want to set localepurge, you need to edit the/ect/locale. nopurge file.

Based on the software you have installed, this will save you several megabytes of disk space.

Example:

If I try to use apt-get to install the dicus software:

Sudo apt-get install discus

After the software is installed, you will see the following prompt:

Localepurge: Disk space freed in/usr/share/locale: 41860 K

Remove an empty package

If you want to remove the orphan package, you need to install deborphan:

Install deborphan in Ubuntu:

Sudo apt-get install deborphan

Use deborphan to open the terminal and enter the following command:

Sudo deborphan | xargs sudo apt-get-y remove -- purge

Use GtkOrphan to remove an orphan package

GtkOrphan (a Perl/Gtk2 application for debian) is a graphical tool used to analyze the status of the user's installation process and find files in isolated libraries. It provides a GUI front-end for deborphan, it also has the function of removing software packages.

Install GtkOrphan in Ubuntu, open the terminal, and run the following command:

Sudo apt-get install gtkorphan

Remove an orphan package with Wajig

Wajig is a simple software package management frontend in the Debian package management system. It uses apt, apt-cache, dpkg,/etc/init. d. The script is integrated with a single command. It is designed to be simple to use and provide rich documentation for all its functions.

With proper sudo configuration, most (if not all) software package installation and creation tasks can be completed through a user shell. Wajig is also applicable to general system management. In addition, a Gnome GUI command gjig is also included in this package.

Install Wajig in Ubuntu, open the terminal, and run the following command:

Sudo apt-get install wajig

Debfoster --- tracking your operations during installation

Debfoster maintains a list of software packages that are explicitly required to be installed, but does not include software packages that are installed as dependencies of a software. The parameters are completely optional. You can even activate debfoster immediately after each running of dpkg and/or apt-get.

In addition, you can use debfoster in the command line to install or remove certain software packages. Packages with the suffix --- will be removed, and those without the suffix will be installed.

If a new software package or debfoster notices that the software package on which a software package depends is an orphan package, debfoster will ask you how to proceed. If you decide to keep this orphan package, debfoster will only record and continue the installation process; if you think this package is not enough to interest you, after debfoster asks this question, it will remove this software package. Further, if you decide to turn other software packages into standalone packages, more questions will come soon.

Install debfoster in Ubuntu, open the terminal, and run the following command:

Sudo apt-get install debfoster

Use debfoster

To create an initial trace file, run the following command:

Sudo debfoster-q

You can always edit the/var/lib/debfoster/keepers file to define the packages you want to stay in the system.

To edit this file, type:

Sudo vi/var/lib/debfoster/keepers

To force debfoster to remove all software packages not listed in the file above, or install them as dependencies of software packages listed in the file, it also adds all software packages that are not installed in this list. To perform related operations based on the list, you only need to execute:

Sudo debfoster-f

To track your newly installed software packages, you need to execute the following commands from time to time:

Sudo debfoster

Xdiskusage -- check where your hard disk space is
