powerlevel9k Theme for ZSH
Powerlevel9k is a theme for ZSH which uses Powerline Fonts. It can be used with vanilla ZSH, Oh-My-Zsh, or Prezto, and can also be installed using antigen.
Be a badass. Get more out of your terminal. Impress everyone in 'Screenshot Your Desktop' threads. Use powerlevel9k.
You can check out some other users' configurations in our wiki: Show Off Your Config.
There are a number of Powerline ZSH themes available, now. The developers of this theme focus on four primary goals:
- Give users a great out-of-the-box configuration with no additional configuration required.
- Make customization easy for users who do want to tweak their prompt.
- Provide useful segments that you can enable to make your prompt even more effective and helpful. We have prompt segments for everything from unit test coverage to your AWS instance.
- Optimize the code for execution speed as much as possible. A snappy terminal is a happy terminal.
Here is powerlevel9k
in action, with some simple settings.

Installation
There are two installation steps to go from a lame terminal to a "Power Level 9000" terminal. Once you are done, you can optionally customize your prompt.
No configuration is necessary post-installation if you like the default settings, but there are plenty of segment customization options available if you are interested.
Prompt Customization
Be sure to check out the wiki page on the additional prompt customization options, including color and icon settings: Stylizing Your Prompt
Customizing Prompt Segments
Customizing your prompt is easy! Select the segments you want to have displayed,
and then assign them to either the left or right prompt by adding the following
variables to your ~/.zshrc
. If you don't customize this, the below
configuration is the default:
POWERLEVEL9K_LEFT_PROMPT_ELEMENTS=(context dir rbenv vcs)
POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS=(status history time)
Available Prompt Segments
The segments that are currently available are:
- aws - The current AWS profile, if active.

aws
If you would like to display the current AWS
profile, add
the aws
segment to one of the prompts, and define AWS_DEFAULT_PROFILE
in
your ~/.zshrc
:
export AWS_DEFAULT_PROFILE=<profile_name>
battery
This segment will display your current battery status (fails gracefully on systems without a battery). It can be customized in your .zshrc with the environment variables detailed below with their default values.
POWERLEVEL9K_BATTERY_CHARGING="yellow"
POWERLEVEL9K_BATTERY_CHARGED="green"
POWERLEVEL9K_BATTERY_DISCONNECTED=$DEFAULT_COLOR
POWERLEVEL9K_BATTERY_LOW_THRESHOLD=10
POWERLEVEL9K_BATTERY_LOW_COLOR="red"
In addition to the above it supports standard _FOREGROUND value without affecting the icon color
Supports both OS X and Linux(time remaining requires the acpi program on Linux)
custom_command
The custom_...
segment allows you to turn the output of a custom command into
a prompt segment. As an example, if you wanted to create a custom segment to
display your WiFi signal strength, you might define a custom segment called
custom_signal
like this:
POWERLEVEL9K_LEFT_PROMPT_ELEMENTS=(context time battery dir vcs virtualenv custom_signal)
POWERLEVEL9K_CUSTOM_SIGNAL="echo signal: \$(nmcli device wifi | grep yes | awk '{print \$8}')"
POWERLEVEL9K_CUSTOM_SIGNAL_BACKGROUND="blue"
POWERLEVEL9K_CUSTOM_SIGNAL_FOREGROUND="yellow"
POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS=(aws status load ram)
Instead of writing out the command in-line within the environment variable, you
can also add it as a function in your .zshrc
:
zsh_signal(){
local signal=$(nmcli device wifi | grep yes | awk '{print $8}')
local color='%F{yellow}'
[[ $signal -gt 75 ]] && color='%F{green}'
[[ $signal -lt 50 ]] && color='%F{red}'
echo -n "%{$color%}\uf230 $signal%{%f%}" # \uf230 is
}
You would then invoke the function in your custom segment:
POWERLEVEL9K_CUSTOM_SIGNAL="zsh_signal"
The command, above, gives you the wireless signal segment shown below:
You can define as many custom segments as you wish. If you think you have a segment that others would find useful, please consider upstreaming it to the main theme distribution so that everyone can use it!
context
The context
segment (user@host string) is conditional. This lets you enable
it, but only display it if you are not your normal user or on a remote host
(basically, only print it when it's likely you need it).
To use this feature, make sure the context
segment is enabled in your prompt
elements (it is by default), and define a DEFAULT_USER
in your ~/.zshrc
:
export DEFAULT_USER=<your username>
dir
The dir
segment shows the current working directory. You can limit the output
to a certain length:
# Limit to the last two folders
POWERLEVEL9K_SHORTEN_DIR_LENGTH=2
To change the way how the current working directory is truncated, just set:
# truncate the middle part
POWERLEVEL9K_SHORTEN_STRATEGY="truncate_middle"
# truncate from right, leaving the first X characters untouched
POWERLEVEL9K_SHORTEN_STRATEGY="truncate_from_right"
# default behaviour is to truncate whole directories
You can also change the delimiter (the dots in between text) from 2 dots to something custom:
# set the delimiter to an empty string to hide it
POWERLEVEL9K_SHORTEN_DELIMITER=""
# or set it to anything else you want (e.g. 3 dots)
POWERLEVEL9K_SHORTEN_DELIMITER="..."
For example, if you wanted the truncation behavior of the fish
shell, which
truncates /usr/share/plasma
to /u/s/plasma
, you would use the following:
POWERLEVEL9K_SHORTEN_DIR_LENGTH=1
POWERLEVEL9K_SHORTEN_DELIMITER=""
POWERLEVEL9K_SHORTEN_STRATEGY="truncate_from_right"
In each case you have to specify the length you want to shorten the directory
to. So in some cases POWERLEVEL9K_SHORTEN_DIR_LENGTH
means characters, in
others whole directories.

To turn off these icons you could set these variables to an empty string.
POWERLEVEL9K_HOME_ICON=''
POWERLEVEL9K_HOME_SUB_ICON=''
POWERLEVEL9K_FOLDER_ICON=''
ip
This segment shows you your current internal IP address. It tries to examine all currently used network interfaces and prints the first address it finds. In the case that this is not the right IP address you can specify the correct network interface by setting:
POWERLEVEL9K_IP_INTERFACE="eth0"
rspec_stats
See Unit Test Ratios, below.
status
This segment shows the return code of the last command. By default, this
segment will always print, but you can customize it to only print if there
is an error by setting the following variable in your ~/.zshrc
.
POWERLEVEL9K_STATUS_VERBOSE=false
ram
By default this segment shows you free RAM and used Swap. If you want to show
only one value, you can specify POWERLEVEL9K_RAM_ELEMENTS
and set it to either
ram_free
or swap_used
. Full example:
# Show only used swap:
POWERLEVEL9K_RAM_ELEMENTS=(swap_used)
symphony2_tests
See Unit Test Ratios, below.
time
By default the time is show in 'H:M:S' format. If you want to change it,
just set another format in your ~/.zshrc
. As an example, this is a reversed
time format:
# Reversed time format
POWERLEVEL9K_TIME_FORMAT='%D{%S:%M:%H}'
If you are using an "Awesome Powerline Font", you can add a time symbol to this segment, as well:
# Output time, date, and a symbol from the "Awesome Powerline Font" set
POWERLEVEL9K_TIME_FORMAT="%D{%H:%M:%S \uE868 %d.%m.%y}"
vcs
By default, the vcs
segment will provide quite a bit of information. If you
would also like for it to display the current hash / changeset, simply define
POWERLEVEL9K_SHOW_CHANGESET
in your ~/.zshrc
. If activated, it will show
the first 12 characters of the changeset id. To change the amount of characters,
set POWERLEVEL9K_CHANGESET_HASH_LENGTH
to any value you want.
# enable the vcs segment in general
POWERLEVEL9K_SHOW_CHANGESET=true
# just show the 6 first characters of changeset
POWERLEVEL9K_CHANGESET_HASH_LENGTH=6
You can also disable the branch icon in your prompt by setting
POWERLEVEL9K_HIDE_BRANCH_ICON
to true
:
# Hide the branch icon
POWERLEVEL9K_HIDE_BRANCH_ICON=true
vcs Symbols
The vcs
segment uses various symbols to tell you the state of your repository.
These symbols depend on your installed font and selected POWERLEVEL9K_MODE
from the Installation section above.
vi_mode
This segment shows ZSH's current input mode. Note that this is only useful if
you are using the ZSH Line Editor
(VI mode). You can enable this either by .zshrc
configuration or using a plugin, like
Oh-My-Zsh's vi-mode plugin.
If you want to display a string other than "NORMAL" or "INSERT" in command
and
insert-mode
, you can do so by setting the following variables in your
~/.zshrc
:
POWERLEVEL9K_VI_INSERT_MODE_STRING="INSERT"
POWERLEVEL9K_VI_COMMAND_MODE_STRING="NORMAL"
Unit Test Ratios
The symfony2_tests
and rspec_stats
segments both show a ratio of "real"
classes vs test classes in your source code. This is just a very simple ratio,
and does not show your code coverage or any sophisticated stats. All this does
is count your source files and test files, and calculate the ratio between them.
Just enough to give you a quick overview about the test situation of the project
you are dealing with.
