Freebsd 最獨特的地方就在於ports 的便利性，透過ports來找到所需的軟體並安裝也無須擔心相容性或是相依性的問題，又可以持續更新ports的軟體，這篇主要是介紹如何更新ports tree 讓安裝程式時ports tree保持在最新的狀態 😀
開始用Ports安裝應用軟體：
cd /usr/ports/net/cvsup-without-gui; make install clean
cd /usr/ports/sysutils/portupgrade ; make install clean
cd /usr/ports/ftp/wget ; make install clean
cd /usr/ports/security/sudo ; make install clean
cd /usr/ports/shells/bash2 ; make install clean
cd /usr/ports/ftp/ncftp3 ; make install clean
cd /usr/ports/mail/imap-uw ; make install clean
cd /usr/ports/mail/qpopper ; make install clean
cd /usr/ports/security/pidentd ; make install clean
cd /usr/ports/misc/gnuls ; make install clean
其中，cvsup-without-gui 與 portupgrade 是屬於系統更新( src 及 ports-tree )
的工具軟體，建議您一定要裝。
查看安裝之後的結果：
