Apt-get remove man pages

Advanced Package Tool , or APT , is a free-software user interface that works with core libraries to handle the installation and removal of software on Debian , Ubuntu , and related Linux distributions. APT is a collection of tools distributed in a package named apt. Three such programs are apt , apt-get and apt-cache. They are commonly used in examples of APT because they are simple and ubiquitous.

APT Cheat Sheet

Reducing the size of the Debian Installation Footprint It may be useful to reduce the size of the installation footprint on Embedded systems, or on older computers or laptops with limited drive space, or in cases where a small installation is preferred. Minimal systems in general also carry security benefits because fewer packages means that there are fewer security exploits available. Have not found a recursive option!

If LILO or something else is used change this! Remove unnecessary packages in general Apt has an inbuilt feature to remove files that are no longer required by your system. Run the following command to remove unnecessary packages: apt autoremove Unfortunately, apt does not always manage to find and purge all unused files.

Therefore, the best solution to removing unnecessary packages is to not install them in the first place. To find such packages run: deborphan --guess-all Be careful when removing suggested packages, as they may have package dependencies that may still required by your system.

Packages can be deleted manually if needed be and you know what you are doing. Remove unnecessary locale files The introduction of LanguagePacks tdebs may also help in reducing the size of the installation footprint. It is recommended that the number of locale configurations installed is kept to a minimum. A side effect or reducing the number of locale options is that the compilation of the glibc library gets a lot faster.

ToDo : complete this section Note: See the dpkg filters. The gain is extremely minor, and there's no much point in doing this. Replace the getty processes with the ngetty single process daemon The getty processes can be replaced by the ngetty single process daemon to reduce virtual memory utilization: Use busybox built-ins instead of full packages You can use the tiny busybox tools instead of installing full packages.

Run busybox to see which applets are available. Add busybox less to the Debian Alternatives System as pager Debian Alternatives System doesn't link to two words like "busybox less". Do this with care, some systems are not supported by UPX, and some binaries break.

How to use Linux Commands

Don't confuse the three commands used for upgrading a Debian- or Ubuntu-based machine. Instead, learn what each can do. How to upgrade a Debian-based Linux distribution--let me count the ways. There's an apt-get upgrade, apt-get dist-upgrade, and do-release-upgrade.

The tutorial does not explain how to remove a repository added with add-apt-repository. The --remove option mentioned on the man page for Ubuntu A little precision though: besides maybe LMDE, in Linux Mint the password you have to enter for sudo is your own, not the one for root.

In fact, first in the list of things to do after installing Ubuntu is to use apt-get update and apt-get upgrade. Now, you might be aware of a few apt-get commands and their usage, but you might not be aware of some others. In this guide for beginners, I am going to explain various of apt-get commands with examples so that you can use them as well as an expert Linux user. Download apt-get command cheatsheet for future reference. You can print it or save it for offline viewing.

Join , subscribers and get a daily digest of news, geek trivia, and our feature articles. APT, the Advanced Package Tool from the Debian project, is for managing packages by using a lot of separate tools to accomplish various tasks. In the past, users needed to know multiple command structures like apt-get, apt-cache, apt-config, and many more to utilize the full feature-set of APT. APT was created originally to solve a lot of package management problems like putting an end to the dependency hell that so many people experienced in the early days of Linux-based operating systems. The documentation related to APT is scattered in various different tools and in some cases, such as the main apt command, practically impossible to find. Using apt instead will save time and save the amount of keystrokes required to accomplish the same task. The fundamental problem with the documentation regarding APT is that depending on where you look and how you look, you may or may not find anything at all. Man Pages are documentation pages that can be used locally on your system or via online directories. Local entries may or may not be up to date depending on the version of your distro.

Specifically on a raspberry pi running Raspbian Wheezy , but also in general, can I disable all man pages? This would mean no stored man pages, no "processing triggers for man-db", and so on and so forth. With the manual pages always available on the internet, I don't really need them installed, and generating and storing them seems unnecessary. I was having the opposite problem on a Debian 8 image which somebody had put together for a Wandboard.

Reducing the size of the Debian Installation Footprint

One of the biggest changes that catches Windows users moving to Linux is the way that software is installed. Instead of downloading an executable file from some website or other, running it and hoping it doesn't clobber your existing library files DLLs or install some dubious adware or malware, Linux distributions maintain repositories of software, which are all packaged up for that distro and tested for compatibility with the rest of the distro. On this page of our guide to everything you need to know about Linux Commands, we will look at how this is done by distros that use the Advanced Packaging Tool apt software management system, as developed by Debian and used by distros from Ubuntu to Raspbian on the Raspberry Pi. A repository is a collection of software packages for a distro. Each major release of a distro will have its own repositories, and the packages will have been built for and tested with that release, but a repository is more than a collection of files. Each repo as they are usually called is indexed, making it easy to find what you want.

May 6, - Apt-get upgrade does not remove packages, it only upgrades. to read up on the apt-get and do-release-upgrade man pages to find out more.

It is intended as an end user interface and enables some options better suited for interactive usage by default compared to more specialized APT tools like apt-get 8 and apt-cache 8. Much like apt itself, its manpage is intended as an end user interface and as such only mentions the most used commands and options partly to not duplicate information in multiple places and partly to avoid overwhelming readers with a cornucopia of options and details. Other commands operate on this data to e. New packages will be installed if required to statisfy dependencies, but existing packages will never be removed.
