	~~== 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'~~
