To do this, cd to the Ports directory of that application. For example, if we wanted to uninstall bash :. This will remove the application from your system. Note that this method will work even if you originally installed the application through Packages rather than Ports. Additionally, installing an application from a port can help a user understand how the application is compiled, configured, and finally built into a binary. It can be a very rewarding process!
Before we start, ensure you have a working installation of FreeBSD. If you do not, you can follow these installation walkthroughs:. If you installed FreeBSD or a similar variant e. Then, after logging in, you should see a welcome screen and a shell prompt appear similar to this:.
You should upgrade or use an alternative browser. Properly deinstall ports and dependencies. Thread starter decsis Start date Oct 31, After reading the whole handbook, I'm still quite unsure how I properly uninstall ports I don't need and especially, how I remove their dependencies.
For example I installed firefox So before reading the handbook , I typed Code:. SirDice Administrator Staff member. Either that or doing it by hand. We also usually want to clean up a bit after the installation to reclaim disk space and keep a clean system. We can do this with the clean or distclean targets. The clean target deletes the extracted source code used to build this port and any dependency ports.
This will prompt you to configure the port and any dependencies at the beginning of the process. Afterwards it will download and verify the integrity of the source archive. It will then change contexts to fulfill any missing dependencies.
When that process is complete, it will return to the port in question, extract the archive, apply any necessary patches, and configure it according to the options you selected. It will then compile the application and install it on your system. Afterwards, it will remove the expanded source code for this port and any dependencies. It will then delete the source archive for this port. You will be presented with a single dialog box for the application. If you are using one of the listed shells, you can choose to configure shell completion for the tool here:.
The port will be downloaded, configured, and installed. If you are using the default tcsh , you will want to rescan your PATH after every installation so that your shell environment is aware of all of the installed applications:.
Keep this in mind when you are configuring or starting applications. One thing to keep in mind is that if you are installing a port that will be run as a service, the installation procedure will not start the service automatically.
In fact, there are a few steps that you must take in order to start the services within FreeBSD. Assuming that any necessary configuration has been complete, this will start the service a single time.
If you want to stop the service as a later time, you can type:. While this works for quick tests, it is not the ideal way to manage services in FreeBSD.
To configure your service to start at each boot, you must enable it. This will cause the rsync daemon to be started every boot. For instance, you can start the service by typing:. If you have installed a port that you no longer need, you can remove the application from your system using a similar but more straight-forward process. We can use the deinstall target to remove an application from our system.
Again, change to the directory within the ports tree associated with the application you wish to remove:. If you would also like to delete the options you configured for this port, you can do so by typing:. Now that you know how to install or remove programs, we should demonstrate how to keep your applications up-to-date.
Failure to read this file and apply its advice prior to updating applications can leave your system in an unusable state or affect the functionality of your applications. The information above are the old timestamps.
We can tell from this information that we need to pay attention to any entries from December 11th until the current date. This file contains every potentially breaking change for every available port going all of the way back to You only need to pay attention to the notices that:.
So, for this example, we would only need to pay attention to notices that have been added since December 11th involving our installed ports. If you do not know which ports are installed on your system, you can use portmaster to create a complete list:. The output will be divided into sections according to their dependency relationships.
If any manual steps are required, complete those before continuing on with the rest of the update. One other consideration to keep in mind when updating is whether the software installed on your system has any known security vulnerabilities.
FreeBSD maintains a vulnerability database that you can check to see whether any of your ports or packages have security problems. This functionality is included in the pkg tool. Run a security audit by typing:. It will then check the versions of all of your installed ports or packages and compare them against the entries in the security database. If any ports or packages installed on your system have known vulnerabilities in the database, you will be alerted.
Typically, these will have at least an up-to-date port available that patches the issue. Below, we will discuss how to update all of the ports on your system or just a subset. Regardless of your update strategy, it is essential that you at least update the ports that have known security vulnerabilities. To see which ports have updates available, you can use the portmaster command with the -L flag:.
This provides a similar output to the lowercase variant of the option that we used earlier, but it checks for available updates as well.
