If, as root, '''which cvsup''' does not return the location of your cvsup install, you will need to install [[cvsup]] or [[cvsup-without-gui]] as described in [[Ports,_Installing]]. The cvsup program is the same as cvsup-without-gui if you do not have the X system installed, but many people prefer the non-gui version, as the ''cvsup'' version defaults to working in an X11 window (overridden with the -g flag).

''cvsup -g standard-supfile''

The first time you run this command, it will probably take a significant amount of time. It will go out to the server you picked in the supfile, and attempt to update all of the source code needed to update FreeBSD to whatever version you have picked.

In a perfect world, that will always work. The only times when it wont are when you don't have connectivity or the server that you're cvsup-ing against is not allowing connections. The ''-g'' switch just makes sure that the GUI stuff in the regular CVSup program doesn't run, which many users prefer.

When updating your FreeBSD system, you'll first want to sync your sources to the live sources. This was previously offered via cvs. If you hail from a Windows environment, you may think of keeping your sources updated as about the first half of the FreeBSD procedure which corresponds to Windows Update. There are two major systems that most users will want to keep up to date, the source tree (described here), and the ports tree (described in Updating the ports tree).

The source tree is the actual code for the kernel and the fundamental system programs (collectively known as the 'world') for the FreeBSD operating system.

CVS for updating FreeBSD sources, ports and base is depreciated. This function has been replaced by subversion and CTM. FreeBSD: Source code repositories

[edit] Subversion

An easy way to update through subversion is to install svnup; edit its configuration file; then run the command with the option set in /usr/local/etc/svnup.conf.

Partial svnup.conf file: 

host=[choose server]  # uncomment one of these lines
#
[release]
branch=base/releng/10.1
target=/usr/src

The command to run with arguments in this example is: 

% svnup release

[edit] ctm

Ctm is another way to update source files. It appears that this method has security issues. Please see the FreeBSD Handbook (Appendix A), and ctm's man page for more details.

[edit] It's updated. Now what?

Well... since you ended up here in the first place... I'm guessing you either came from Upgrading_the_base_system, Custom Kernel or Updating the system. Usually you update the source to do one of the first two.
