FreeBSD Ports

Recursively Configure Ports

make config-recursive

Ports Update / Upgrade

portsnap fetch
portsnap update

or if you are doing this the first time, run: 

portsnap fetch
portsnap extract

You may also get the ports from svn: 

svn co svn://svn.freebsd.org/base/releng/9.1 /usr/src
svn up /usr/src


Upgrade FreeBSD

# mv /usr/src /usr/src.old
# svn co svn://svn.freebsd.org/base/release/9.1.0 /usr/src

To build and install 9.1-RELEASE: 

# mergemaster -p
# cd /usr/src
# make buildworld
# make buildkernel
# make installkernel
# reboot
# cd /usr/src
# make installworld
# mergemaster -iU
# reboot

User Management

FreeBSD

Create a new user with a home directory /home/username: 

pw useradd -n username -s /bin/sh -m

Remove a user and their home directory: 

pw userdel -n username -r


Create a new group 

pw groupadd groupname

Show group 

pw groupshow groupname

Set user to group 

pw groupmod groupname -M username,user2,user3

Add user to group 

pw groupmod groupname -m user4
