iTerm 2

iTerm2 is a replacement for Terminal, it brings the terminal into the modern age with useful features making it more productive and customisable. You can download iTerm 2 from the official website.

Installing Zsh

Open up iTerm then run the following code:

sudo apt-get install zsh

Once the install is completed check that it was installed correctly by running:

zsh --version


If you have any problems installing Zsh, take a look at the Zsh installation guide.

Making Zsh your default shell without root access

Make it your default shell by running:

chsh -s $(which zsh)

Quit the terminal then re-run it typing in:

echo $SHELL
it should output /bin/zsh

If that didn’t work try this:

Within your home directory create these files (you may already have these files) and add the following codes to use Zsh as default shell.
.bash_profile

export SHELL=/bin/zsh
exec /bin/zsh -l


.profile

export SHELL=/bin/zsh
[ -z "$ZSH_VERSION" ] && exec /bin/zsh -l
