- All right.
In this lesson, we have seen many commands.
Let's go check them out.
It started with rpm,
the command that previously was used to install packages
and nowadays is mainly useful for querying packages.
Yum, as well as dnf, are the software managers
in record environments,
your main source for installing packages,
and apt is the equivalent in Ubuntu.
Apt-cache is a useful command
because there is apt-cache search which allows you to search
for packages containing a specific file.
And that's really useful if you don't know
the name of the packages that you need.
