It is also possible to use pacman to search Manjaro's software repositories for any desired software, provided you know the name of what you want. The ''sudo'' prefix is not required for this.

== Installing | == Orphaned Software Packages == | ||
To list all ''orphans'' - that is, installed packages that are not used by anything else and that consequently serve no purpose - enter the following command: | |||
pacman -Qdt | |||
'''It is highly recommended to remove orphans from your system, as although harmless, they still serve no purpose other than to take up room and resources. Rather than having to remove them one-by-one, the following command will search for and remove them for you: | |||
sudo pacman -Sc $(pacman -Qdtq) | |||
== Listing Information about Installed Packages == | |||
To list all dependencies of a particular software package (i.e. other software that requires the specified software package in order to work), enter the following command: | |||
pactree [software package name] | |||

Fortunately, pacman will automatically detect and install these for you.}} | {{tip| many software packages (especially complex applications) will require other software packages - known as ''dependencies'' - to also be downloaded and installed in order to work. Fortunately, pacman will automatically detect and install these for you.}} | ||
It is also possible to download software packages without actually installing them by entering the following command: | |||
sudo pacman -Sw [software package name] | |||
===Packages Located Locally or From the Internet=== | |||
To install a package already downloaded onto your system (the file name should end in '''pkg.tar.xz'''), the basic syntax is: | |||
sudo pacman -U [/package_path/][software package name.pkg.tar.xz] | |||
For example, to install a package located in the ''Downloads'' folder, the following command would be entered: | |||
sudo pacman -U ~/Downloads/[software package name.pkg.tar.xz] | |||
To install a package via a URL (i.e. located elsewhere on the internet), the basic syntax is: | |||
pacman -U http://www.examplepackage/repo/examplepkg.tar.xz | |||
