Powerline is a Python‑based status‑line plugin for Vim that also provides prompts for Bash, Zsh, tmux and other applications. It enhances the editor by showing mode, file name, path, line/column numbers, Git branch, virtual environment and more.

Key Features

Written in Python, extensible and feature‑rich.

Stable code base compatible with Python 2.6+ and Python 3.

Supports prompts and status bars in many Linux tools.

Configuration and color themes use JSON.

Lightweight with daemon support for better performance.

The article shows how to install Powerline and its fonts on both RHEL‑based and Debian‑based Linux distributions.

Installing Powerline

Powerline is published on PyPI under the package name powerline-status. First install pip using your distribution’s package manager:

$ sudo apt install python3-pip         # Debian/Ubuntu/Mint
$ sudo yum install python3-pip         # RHEL/CentOS/Fedora/Rocky/AlmaLinux
$ sudo emerge -a dev-lang/pip          # Gentoo
$ sudo apk add py3-pip                 # Alpine
$ sudo pacman -S python-pip            # Arch
$ sudo zypper install python3-pip      # OpenSUSE

Next, install Git if it is not already present:

$ sudo apt install git    # Debian/Ubuntu/Mint
$ sudo yum install git    # RHEL/CentOS/Fedora/Rocky/AlmaLinux
$ sudo emerge -a git     # Gentoo
$ sudo apk add git       # Alpine
$ sudo pacman -S git     # Arch
$ sudo zypper install git # OpenSUSE

Then install Powerline itself: $ pip install powerline-status If you encounter the error externally-managed-environment, remove the marker file and retry:

$ sudo rm -rf /usr/lib/python3.x/EXTERNALLY-MANAGED

Alternatively, install Powerline directly from your package manager:

$ sudo apt install powerline         # Debian/Ubuntu/Mint
$ sudo yum install powerline         # RHEL/CentOS/Fedora/Rocky/AlmaLinux
$ sudo emerge -a sys-apps/powerline  # Gentoo
$ sudo apk add powerline             # Alpine
$ sudo pacman -S powerline           # Arch
$ sudo zypper install powerline      # OpenSUSE

Installing Powerline Fonts

Powerline uses special glyphs, so you need to install the Powerline symbols font or patched fonts.

If you installed Powerline via pip:

$ wget https://github.com/powerline/powerline/raw/develop/font/PowerlineSymbols.otf
$ wget https://github.com/powerline/powerline/raw/develop/font/10-powerline-symbols.conf
$ sudo mv PowerlineSymbols.otf ~/.local/share/fonts/
$ sudo fc-cache -vf ~/.local/share/fonts/
$ sudo mv 10-powerline-symbols.conf ~/.config/fontconfig/conf.d/

If you installed via a package manager:

$ sudo apt install fonts-powerline         # Debian/Ubuntu/Mint
$ sudo yum install powerline-fonts         # RHEL/CentOS/Fedora/Rocky/AlmaLinux
$ sudo emerge -a sys-apps/powerline-fonts  # Gentoo
$ sudo apk add powerline-fonts             # Alpine
$ sudo pacman -S powerline-fonts           # Arch
$ sudo zypper install powerline-fonts      # OpenSUSE

Enabling Powerline in Bash

Add the following lines to ~/.bashrc (adjust the path according to the output of pip show powerline-status):

export TERM="screen-256color"
POWERLINE_BASH_CONTINUATION=1
POWERLINE_BASH_SELECT=1
source /home/youruser/.local/lib/python3.10/site-packages/powerline/bindings/bash/powerline.sh

After re‑logging, you will see a colorful prompt with breadcrumb navigation, background job indicators, and host name when using SSH.

Enabling Powerline in Vim

Add the following to ~/.vimrc:

python3 from powerline.vim import setup as powerline_setup
python3 powerline_setup()
python3 del powerline_setup
set laststatus=2

Start Vim to see the new status line.
