一些Freebsd 的 port用法 -portmaster , portaudit

Portmaster makes life easy when upgrading most of the packages even if there are other packages depend on it, for example if you have Apache Server and you want to upgrade eXpat you have to uninstall eXpat and install the new version, doing this will break the Apache installation, Portmaster can be used to do this operation safely without breaking any links ..etc.

To install Portmaster do the following:

cd /usr/ports/ports-mgmt/portmaster
make install clean
rehash

Portaudit is a nice application which will check the vulnerability database when building ports to ensure that there is no known security issues with what you are installing, if there is a known issue if wont continue and will reference you to the vulnerability.

To install it do the following:

cd /usr/ports/ports-mgmt/portaudit
make install clean
rehash

If you want to install a program even if it has a known vulnerability you can do that using the following command:

make -D DISABLE_VULNERABILITIES install clean
