Changing User Password in Ubuntu Terminal

Note: If you are not familiar to using the terminal, you will find the space remains empty/blank as you type your existing and new password. Since I am new to using Ubuntu and really any terminal, I am needing a space to save even the simplest of commands.

sudo passwd <username>      *username will not go into < >'s*
[sudo] password for <username>: 
New password: 
Retype new password: 
passwd: password updated successfully
