Installing a package:
* [http://susefaq.sourceforge.net/articles/rpm.html RPM RedHat Package Manager]
* [http://linuxgazette.net/issue68/nazario.html Using RPM: THe Basics (Part I)]
* '''Install commands'''
<source lang="bash">
<source lang="bash">
rpm -ivh package # Installing a package - verbose and progress bars
# ----- Installing from the REPOSITORIES
apt-get update # (OPTIONAL) update the local repository cache
rpm -iv -nodeps package # Installing a package (verbose), ignore dependencies
</source>
apt-get install <package(s)> # Install given package
* '''Query commands'''
apt-get upgrade # Install new version of all installed package (without installing new package)
<source lang="bash">
apt-get remove <package(s)> # Remove package (or install it if package name prefixed with - )
apt-get purge <package(s)> # Remove package and related configuration files
rpm -ql package # List files provided by a package
</source>
apt-get autoremove # Remove package installed to satisfy dependencies for some package and that are no more needed
:* To query a package that has '''not been installed''', add '''-p''' option to the command:
# ----- Installing from a .deb PACKAGE file
<source lang="bash">
dpkg --install <debfile> # (or -i) Install a package from given .deb file
rpm -qpl package # List files provided by a package
</source>
</source>


== Source package ==
Querying the '''cache''' or '''installed''' packages:
Installing from source package is usually done with
<source lang=bash>
<source lang="bash">
# ----- Querying INSTALLED PACKAGE
./configure
dpkg --get-selections # Show the list of packages installed through apt-get
make
dpkg --get-selections | grep php # ... filtering for some specific package keyword
sudo make install
dpkg -L <package> # List files delivered by a given <package>
dlocate -L <package> # ... same as above but much faster (require package dlocate)
dpkg -S <file> # List packages providing given file
dlocate -S <file> # ... same as above but much faster (require package dlocate)
dlocate <file> # ... same as dpkg -L -S combined but much faster (require package dlocate)
# ----- Querying the CACHE
apt-cache search <regex> # Search package cache (package name and description) for given <regex>
apt-cache search --name-only <regex> # ... same but only search in package name
apt-cache showpkg <package(s)> # Show version and dependencies information about given package(s)
apt-cache show <package(s)> # Show information (description...) about given package(s)
# ----- Querying a .deb PACKAGE file
dpkg --info <debfile> # (or -I) Show information of given .deb file
dpkg --content <debfile> # (or -c) Show content of given .deb file
</source>
</source>
Usually <code>./configure --help</code> gives additional package configuration options (like installing documentation, etc).


;Installing build dependencies
Querying packages that are '''not installed yet''' (requires package '''apt-file'''):<br>
: Building from sources usually requires more dependencies than using the package. If the package is available on the distribution, the easiest way to install these dependencies is usually via <code>apt-get build-dep</code>:
<source lang=bash>
<source lang=bash>
sudo apt-get build-dep udisks
apt-file update # (optional - needed 1st time use)
apt-file list <package> # Search package in repositories, and show the content
apt-file search <file> # Display the name of all packages within repository that contain this file
apt-file search -x "/<file>$" # ... more accurate query using regex
</source>
</source>

;Installing as a package
# Very handy script to query online debian/ubuntu package database.
: Instead of installing with <code>make install</code>, use <code>[https://help.ubuntu.com/community/CheckInstall checkinstall]</code> to create a temporary package that can later be uninstalled with the package manager.

Ubuntu / Debian

See apt.

RPM's

rpm -ivh package                    # Installing a package - verbose and progress bars
rpm -iv -nodeps package             # Installing a package (verbose), ignore dependencies
  • Query commands
rpm -ql package                     # List files provided by a package
  • To query a package that has not been installed, add -p option to the command:
rpm -qpl package                    # List files provided by a package

Source package

Installing from source package is usually done with 

./configure
make
sudo make install

Usually ./configure --help gives additional package configuration options (like installing documentation, etc).

Installing build dependencies
Building from sources usually requires more dependencies than using the package. If the package is available on the distribution, the easiest way to install these dependencies is usually via apt-get build-dep:
sudo apt-get build-dep udisks
Installing as a package
Instead of installing with make install, use checkinstall to create a temporary package that can later be uninstalled with the package manager.
./configure
make
sudo checkinstall                  # Creates a package and install it as if 'sudo make install' was run

#... to uninstall:
sudo dpkg -r <packagename>
Note that checkinstall can actually run any arbitrary command and monitor change on the file system.
