1. Install ZSH and Oh My ZSH

sudo apt-get install zsh
sh -c "$(curl -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"

2. Install powerline font

It has been explained how to install the font here but it didn't work for me unless I used the following command line.

sudo apt-get install fonts-powerline

3. Configure ZSH

To configure ZSH you need to modify its configuration file by opening it with an editor like nano or vim.

nano ~/.zshrc

3.1. Using Theme

Change the content of variable ZSH_THEME to whatever you like; look into the offical themes and change the content of ZSH_THEME="robbyrussell" to the name of the theme.

ZSH_THEME="agnoster"

3.2. Remove Username from Terminal

By default in the Terminal it is shown the username before the place you can write the command with something like user@host. To remove it, it is just needed to add the following code to the end of the file ~/.zshrc .

DEFAULT_USER=$USER

4. Change Theme colors to Solarize

sudo apt-get install dconf-cli
git clone git://github.com/sigurdga/gnome-terminal-colors-solarized.git ~/.solarized
cd ~/.solarized
./install.sh

To activate dark solarize theme in Terminal just right click on the terminal and then go to profile and after that go to Profile Preferences. Then you need to go to the Colors tab and select Solarize Dark/Light form Built-in Schemes.

5. Installing External Theme

You also can use external theme which needs to be installed before using; the way of installing is explained in its own repository. Look into them here. My choice is Power Level 9k.

git clone https://github.com/bhilburn/powerlevel9k.git ~/.oh-my-zsh/custom/themes/powerlevel9k

Then you need to change the ``ZSH_THEMEof the file~/.zshrc``` into ```powerlevel9k/powerlevel9k```.

ZSH_THEME="powerlevel9k/powerlevel9k"

6. Letting Terminal to Understand Farsi/Arabic Characters

First it is needed to install some packages which are explained below.

sudo apt update
sudo apt install libfribidi0 libfribidi-dev
wget https://launchpad.net/~behnam/+archive/ubuntu/ppa/+build/574787/+files/bicon_0.2.0-1ubuntu0~ppa4_amd64.deb
sudo dpkg -i bicon_0.2.0-1ubuntu0~ppa4_amd64.deb
rm bicon_0.2.0-1ubuntu0~ppa4_amd64.deb

Afterwards, it is needed to tell the Terminal to run bicon.bin. To do so, it is needed to edit /usr/share/applications/gnome-terminal.desktop and add the following lines to the end of it.

Terminal=true
Exec=/usr/bin/bicon.bin

7. Installing tmux

For me, Tmux is the combination of Terminator and Screen.

sudo apt-get install tmux

7.1. Cheatlist and Shortcut Keys of tmux

Here are the commands to manage tmux

tmux kill-session -t session_name	Kill a session
tmux kill-session -a	Kill all sessions except the one is active
logout	Logout form the current pane/window (doesn't clsoe it)
exit	Close the current pane/window

And the shortcuts when tmux is run. Note is that ^ means Control key and <alt> means Alt key; <command> means to write a command, <arrow> means the arrow keys and <0-9> means a digit between 0 and 9.

tmux Sessions's Shortcut Keys

^b : <command>	Run a command
^b s	List current sessions

7.2. Changing the tmux Configuration File

To do so it is needed to create/modify a file in the home directory under the name of .tmux.conf.

nano ~/.tmux.conf

For exmaple to change the default prefix which is ^b (or C-b) to something else like ^a (or C-a) which is used in Screen it is needed to unbind the current prefix and add the new one.

unbind C-b
set-option -g prefix C-a
bind C-a send-prefix
