A Powerline like prompt for Bash:
- Shows some important details about the git branch:
- Displays the current git branch which changes background color when the branch is dirty
- A '+' appears when untracked files are present
- When the local branch differs from the remote, the difference in number of commits is shown along with '⇡' or '⇣' indicating whether a git push or pull is pending
- Changes color if the last command exited with a failure code
- If you're too deep into a directory tree, shortens the displayed path with an ellipsis
- Shows the current Python virtualenv environment
- It's all done in a Python script, so you could go nuts with it
-
This script uses ANSI color codes to display colors in a terminal. These are notoriously non-portable, so may not work for you out of the box, but try setting your $TERM to xterm-256color, because that works for me.
-
Patch the font you use for your terminal: see https://github.com/Lokaltog/vim-powerline/wiki/Patched-fonts
-
Clone this repository somewhere:
git clone https://github.com/milkbikis/powerline-bash
-
Create a symlink to the python script in your home:
ln -s <path/to/powerline-bash.py> ~/powerline-bash.py
If you don't want the symlink, just modify the path in the .bashrc command below
-
Now add the following to your .bashrc:
function _update_ps1() { export PS1="$(~/powerline-bash.py $?)" } export PROMPT_COMMAND="_update_ps1"
