When you run a command using sudo in Linux, the Terminal prompts you to type in your password with no visual feedback as you type. We’ll show a quick tweak that will show asterisks (*) when you type in your password in the Terminal.
Downloading files from the PHP mirrors is annoying, because by default the redirector makes the name of the filename change to just “mirror.” So how do you fix this? Luckily wget has a simple argument that you can use to fix it — and it is useful for many scenarios.
Nautilus contains some pre-defined bookmarks that provide quick and easy access to some common folders, such as Music and Pictures, as well as devices such as USB flash drives and network locations. You can add custom bookmarks to quickly access folders you use often.
