Powerline is a great statusline plugin for Vim editor, which is developed in Python and provides statuslines and prompts for many other applications such as bash, zsh, tmux and many more.
- It is written in Python, which makes it extensible and feature rich.
- Stable and testable code base, which works well with Python 2.6+ and Python 3.
- It also supports prompts and statuslines in several Linux utilities and tools.
- It has configurations and decorator colors developed using JSON.
- Fast and lightweight, with daemon support, which provides even more better performance.
In this article, I will show you how to install Powerline and Powerline fonts and how to use with Bash and Vim under RedHat and Debian based systems.
Step 1: Installing Generic Requirements for Powerline
Due to a naming conflict with some other unrelated projects, powerline program is available on PyPI (Python Package Index) under the package name as powerline-status.
To install packages from PyPI, we need a ‘pip‘ (package management tool for installing Python packages). So, let’s first install pip tool under our Linux systems.
Install Pip on Debian, Ubuntu and Linux Mint
# apt-get install python-pip

Done Recommended packages: python-dev-all python-wheel The following NEW packages will be installed: python-pip 0 upgraded, 1 newly installed, 0 to remove and 533 not upgraded.

Install Pip on CentOS, RHEL and Fedora
Under Fedora-based systems, you need to first enable epel-repository and then install pip package as shown.
# yum install python-pip # dnf install python-pip [On Fedora 22+ versions]
Installing: python-pip noarch 7.1.0-1.el7 epel 1.5 M Transaction Summary ================================================================================= Install 1 Package Total download size: 1.5 M Installed size: 6.6 M Is this ok [y/d/N]: y Downloading packages: python-pip-7.1.0-1.el7.noarch.rpm | 1.5 MB 00:00:01 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : python-pip-7.1.0-1.el7.noarch 1/1 Verifying : python-pip-7.1.0-1.el7.noarch 1/1 Installed: python-pip.noarch 0:7.1.0-1.el7 Complete!
Step 2: Installing Powerline Tool in Linux
Now it’s’ time to install Powerline latest development version from the Git repository. 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
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.
# 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
# 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.
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.
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
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:
Powerline helps to set colorful and beautiful statuslines and prompts in several applications, good for coding environments. I hope you find this guide helpful and remember to post a comment if you need any help or have additional ideas.

Hey, thanks for the guide, it worked very well. I had 2 issues and would like to get cleared:
1. for terminal, how do i put arrows at end of path instead of rectangular box?
2. I use yakuake as terminal. powerline worked on it but for vim instead of arrows, weird symbols were shown. can you tell me how to fix that?
I suggest you to go through the powerline documentation for implementing arrows in Vim editor at: https://powerline.readthedocs.io/en/latest/overview.html
Please refer to this youtube video for update content for this article
Ravi will you need help updating this. We are using python3.5 now.
