tree¶

Without being root¶

Install and run tree as not-root on an Ubuntu Linux system where it is not installed. If you have an account on the Swedish HPC centers, you will not have root-access and so have to install tree this way if it is missing.

Create a directory to work in:
```
mkdir ~/tree
```
Change to that directory:
```
cd ~/tree
```
Download tree:
```
apt download tree
```
Extract the files:
```
dpkg-deb -xv ./*deb ./
```
Now you can run the tree command by giving the full path:
```
~/tree/usr/bin/tree
```

In order to run it without having to give the full path, create an alias in your ~/.bashrc file: 1. Open ~/.bashrc without your favourite editor. 2. Add this line at the end or with your other alias’es:

alias tree="$HOME/tree/usr/bin/tree"

3. Save the file. 4. source the file:

source ~/.bashrc

You can now run tree by just giving the command tree.

As root¶

sudo apt install tree
