Unmount:
umount <destination>

== Adding IP Alias ==
=== FreeBSD ===
Add an alias IP of 10.1.1.2. Alias IPs all have a netmask of 255.255.255.255.
 
ifconfig re0 10.1.1.2 netmask 255.255.255.255 alias
 
If you want the changes to be persistent, add the following to <code>/etc/rc.conf</code>
ifconfig_re0_alias0="10.1.1.2 netmask 255.255.255.255 alias"
 
== Set a Gateway (Traffic Forwarder) ==
=== Linux ===
route add -net 10.10.2.0/24 dev INSIDE
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o eth2 (outside) -j MASQUERADE
iptables -A FORWARD -i eth1 -j ACCEPT
 
 
== Upgrading pkgconfig to pkg-config on FreeBSD ==
upgrade from pkgconf
portmaster -o devel/pkgconf devel/pkg-config
 
== Restarting Services ==
=== Linux ===
Use any one of:
/etc/init.d/<service> restart
/etc/init.d/<service> stop && /etc/init.d/<service> start
service <service> restart
 
=== FreeBSD ===
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
 
 
== wget to console ==
 
Use the <code>-O -</code> option to output contents to the console.
 
wget -O - http://google.ca
 
== sed ==
=== Simple search / replace ===


  sed 's/<search>/<replace>/g'
You may also get the ports from svn:
  svn co svn://svn.freebsd.org/base/releng/9.1 /usr/src
svn up /usr/src
