It is written in Python, which makes it extensible and feature rich. +2. Stable and testable code base, which works well with Python 2.6+ and Python 3. +3. It also supports prompts and statuslines in several Linux utilities and tools. +4. It has configurations and decorator colors developed using JSON. +5.

So, let’s first install pip tool under our Linux systems. + +#### Install Pip on Debian, Ubuntu and Linux Mint + +``` +# apt-get install python-pip +``` + +##### Sample Output + +``` +Reading package lists...

For this, your system must have git package installed in order to fetch the packages from Git. + +``` +# apt-get install git +# yum install git +# dnf install git +``` + +Next you can install Powerline with the help of pip command as shown. + +``` +# pip install git+git://github.com/Lokaltog/powerline +``` + +##### Sample Output + +``` + Cloning git://github.com/Lokaltog/powerline to /tmp/pip-WAlznH-build +Running setup.py (path:/tmp/pip-WAlznH-build/setup.py) egg_info for package from git+git://github.com/Lokaltog/powerline +warning: no previously-included files matching '*.pyc' found under directory 'powerline/bindings' +warning: no previously-included files matching '*.pyo' found under directory 'powerline/bindings' +Installing collected packages: powerline-status +Found existing installation: powerline-status 2.2 +Uninstalling powerline-status: +Successfully uninstalled powerline-status +Running setup.py install for powerline-status +warning: no previously-included files matching '*.pyc' found under directory 'powerline/bindings' +warning: no previously-included files matching '*.pyo' found under directory 'powerline/bindings' +changing mode of build/scripts-2.7/powerline-lint from 644 to 755 +changing mode of build/scripts-2.7/powerline-daemon from 644 to 755 +changing mode of build/scripts-2.7/powerline-render from 644 to 755 +changing mode of build/scripts-2.7/powerline-config from 644 to 755 +changing mode of /usr/local/bin/powerline-config to 755 +changing mode of /usr/local/bin/powerline-lint to 755 +changing mode of /usr/local/bin/powerline-render to 755 +changing mode of /usr/local/bin/powerline-daemon to 755 +Successfully installed powerline-status +Cleaning up... +``` + +### Step 3: Installing Powerline Fonts in Linux + +Powerline uses special glyphs to show special arrow effect and symbols for developers. For this, you must have a symbol font or a patched font installed on your systems. + +Download the most recent version of the symbol font and fontconfig configuration file using following [wget command][5]. + +``` +# wget https://github.com/powerline/powerline/raw/develop/font/PowerlineSymbols.otf +# wget https://github.com/powerline/powerline/raw/develop/font/10-powerline-symbols.conf +``` + +Then you need to move the font to your fonts directory, /usr/share/fonts/ or /usr/local/share/fonts as follows or you can get the valid font paths by using command `xset q`. + +``` +# mv PowerlineSymbols.otf /usr/share/fonts/ +``` + +Next, you need to update your system’s font cache as follows. + +``` +# fc-cache -vf /usr/share/fonts/ +``` + +Now install the fontconfig file. + +``` +# mv 10-powerline-symbols.conf /etc/fonts/conf.d/ +``` + +Note: If custom symbols doesn’t appear, then try to close all terminal sessions and restart X window for the changes to take effect. + +### Step 4: Setting Powerline for Bash Shell and Vim Statuslines + +In this section we shall look at configuring Powerline for bash shell and vim editor. First make your terminal to support 256color by adding the following line to ~/.bashrc file as follows. + +``` +export TERM=”screen-256color” +``` + +#### Enable Powerline on Bash Shell + +To enable Powerline in bash shell by default, you need to add the following snippet to your ~/.bashrc file. + +First get the location of installed powerline using following command. + +``` +# pip show powerline-status +Name: powerline-status +Version: 2.2.dev9999-git.aa33599e3fb363ab7f2744ce95b7c6465eef7f08 +Location: /usr/local/lib/python2.7/dist-packages +Requires: +``` + +Once you know the actual location of powerline, make sure to replace the location in the below line as per your system suggested. + +``` +powerline-daemon -q +POWERLINE_BASH_CONTINUATION=1 +POWERLINE_BASH_SELECT=1 +. /usr/local/lib/python2.7/dist-packages/powerline/bindings/bash/powerline.sh +``` + +Now try to logout and login back again, you will see powerline statuesline as shown below. + +[ + ![Bash Powerline Statuslines](http://www.tecmint.com/wp-content/uploads/2015/10/Bash-Powerline-Statuslines.gif) +][6] + +Try changing or switching to different directories and keep a eye on “breadcrumb” prompt changes to show your current location. + +You will also be able to watch pending background jobs and if powerline is installed on a remote Linux machine, you can notice that the prompt adds the hostname when you connect via SSH. + +#### Enable Powerline for Vim + +If vim is your favorite editor, luckily there is a powerful plugin for vim, too. To enable this plugin, add these lines to `~/.vimrc` file. + +``` +set rtp+=/usr/local/lib/python2.7/dist-packages/powerline/bindings/vim/ +set laststatus=2 +set t_Co=256 +``` + +Now you can launch vim and see a spiffy new status line: + +[ + ![Vim Powerline Statuslines](http://www.tecmint.com/wp-content/uploads/2015/10/Vim-Powerline-Statuslines.gif) +][7] + +### Summary + +Powerline helps to set colorful and beautiful statuslines and prompts in several applications, good for coding environments.
