Raspbian uses apt for downloading and installing additional software.
common commands for Apt include:
sudo apt-get update to refresh the package lists.
sudo apt-get upgrade to upgrade all currently installed packages.
sudo apt-get install packageName to install new packages along with
their dependencies.
sudo apt-get remove packageName to uninstall a package.
sudo apt-get autoremove to uninstall all orphaned packages.
sudo apt-get autoclean to remove obsolete package lists.
You can also use Aptitude, a text-mode frontend to Apt.
To launch aptitude, type:
sudo aptitude
When launched, Aptitude presents you with a tiered list of packages:
First tier: Status: Upgradeable, new, installed, not installed,
obsolete, virtual.
second tier: category: Admin, editors, gnome, kde, libs, python,
utils, x11, etc.(the full list is several dozen)
Third tier: License: Main, contrib, non-free
Pressing enter on a heading will expand/collapse it's contents, and
pressing enter on a package name will bring up a page with information
about the package including description, size, architecture, and
maintainer information, dependencies and available versions.
Pressing plus, minus, or underscore with a packagename highlighted
will mark it for installation, removal, or purging. Pressing them on a
list heading will mark all packages under that heading.
pressing lowercase u at the package list will refresh the list,
uppercase U will mark all upgradeable packages for upgrade, and
lowercase g will give you a preview of the changes to be made and
pressing g at the preview will make the changes.
If you make a change that would break something, pressing lowercase e
will bring up Aptitude's suggestion for resolving the problem. You can
cycle through the options with less than and greater than and select
one with exclamation.
Lowercase q will exit the current screen and take you to the previous
one. Pressing lowercase q at the package list or uppercase Q at
anytime will prompt you to exit Aptitude altogether.
Pressing slash brings up a search box, and pressing n after the search
highlights the first result will jump to the next result.
Ctrl+t opens the menus.
Aptitude has other keyboard shortcuts, but these should be more than
enough to get you started.
