Using Remote Repositories
Downloading packages before installing them gets tiresome especially when you forget a dependency and have to go back and download more packages. The Debian project made apt—the Advanced Package Tool—to help out. APT is a series of tools that build on dpkg to add more features. The two utilities that are important for the exam are apt-get and apt-cache.
Installing Remote Packages
The apt-get utility is responsible for most remote software installation operations. Every apt-get invocation is followed by a command that indicates what to do. Use the install command to install a package, as shown in Example 3-2.
