To install applications on a FreeBSD system, you can use the pkg command.
For example, to install the "nano" text editor, you can use the following command:
pkg install nano
This will install the "nano" text editor on the system.
You can find more information about the pkg command and its options in the pkg documentation or by running the pkg help command.
You can also use the pkg search command to search for a specific package. For example:
pkg search nano
This will search for packages with "nano" in their name or description.
To update the package database and install the latest versions of all installed packages, you can use the pkg update and pkg upgrade commands. For example:
pkg update pkg upgrade
The pkg update command updates the package database, and the pkg upgrade command upgrades all installed packages to the latest version.
You can also use the portmaster or portupgrade utility to manage installed packages and ports on a FreeBSD system.
For example, to upgrade all installed packages with portmaster, you can use the following command:
portmaster -a
This will upgrade all installed packages with portmaster.
You can find more information about the portmaster and portupgrade utilities in the FreeBSD documentation or by searching online.
