How to install "tree" with command-line?

Question

How do I install "tree" via apt-get in Terminal? I have been trying to do apt-get update tree but nothing seems to happen.

Is it necessary to include sudo in the command?

Solution

Use this command in Terminal:

sudo apt-get install tree

The command apt-get update only updates the package lists. You need apt-get install and the package name to install a new package.

And yes, sudo is required as you need root privileges in order to install and remove software.

apt-get update updates the list of available packages. Please read man apt-get.

apt is an alias for apt-get, so you can use sudo apt install tree

@ГригорийПерельман: You can use that command, but apt is a separate command, it is not an alias, even if it does use apt-get which I don't know about.
