Usually, the startup scripts are located in <code>/etc/rc.d</code>
/etc/rc.d/<service> restart
However, if it is 3rd party software, they are located in <code>/usr/local/etc/rc.d</code>
/usr/local/etc/rc.d/<service> restart
If you are trying to restart NFS, you may do either:
/etc/rc.d/nsfd restart
kill -HUP `cat /var/run/mountd.pid`
=== Solaris / SunOS ===
The startup scripts are located in <code>/lib/svc/method/<service></code>
/lib/svc/method/<service> restart
svcadm restart <service>
Example: To restart ssh, do any one of:
svcadm restart ssh
svcadm restart svc:/network/ssh
/lib/svc/method/sshd restart

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

Disable SELinux

Temporary: 

echo 0 > /selinux/enforce

Permanently: 

vi /etc/selinux/config
# Change to SELINUX=disabled

Pack & Unpack initird.img

Extracting initrd.img 

mkdir initrd_test
cd initrd_test
gzip -dc < ../initrd.img | cpio -i

Packing initrd.img 

cd initrd_test
find . | cpio -o -c | gzip -9 > ../initrd.img


Create Driver Disk

# Create a blank, 20MB image
dd if=/dev/zero of=driverdisk.img bs=1M count=20

# Format the image with ext2
mkfs -t ext2 -q driverdisk.img

# mount it and copy the files over
mount -o loop driverdisk.img /mnt/driverdisk

# copy drivers to /mnt/driverdisk, then run
umount /mnt/tmp

List Installed Packages

rpm -qa
rpm -qi <package name>
