Liquid prompt -- A useful adaptive prompt for Bash & Zsh

Liquid prompt gives you a nicely displayed prompt with useful information when you need it. It shows you what you need when you need it. You will notice what changes, when it changes saving time and frustration. And you can even use it with your favorite shell, Bash or Zsh.



If there is nothing special in the current context, the liquid prompt is close to a default prompt:

[user:~] $

If you are running a command in the background that is still running and you are in a git repository on a server, on branch "myb":

1r [user@server:~/liquidprompt] myb ±

A liquid prompt displaying everything (a rare event!) may look like this:

code 🕤 ⌁24% ⌂42% 3d/2&/1z [user@server:~/ … /code/liquidprompt][pyenv]↥ master(+10/-5,3)*+ 125 ±

It (may) displays:

  • A tag associated to the current shell session (you can easily add any prefix tag to your prompt, by invoking prompt_tag MYTAG).
  • The current time, either as numeric values or an analog clock,
  • a green ⏚ if the battery is charging, above the given threshold, but not charged, a yellow ⏚ if the battery is charging and under threshold, a yellow ⌁ if the battery is discharging but above threshold, a red ⌁ if the battery is discharging and under threshold;
  • the average of the batteries remaining power, if it is under the given threshold, with a colormap, going more and more red with decreasing power;
  • the average of the processors load, if it is over a given limit, with a colormap that becomes more and more noticeable with increasing load;
  • the average temperature of the available sensors in the system (generally CPU and MB);
  • the number of detached sessions (screen or tmux), if there are any;
  • the number of attached sleeping jobs (when you interrupt a command with Ctrl-Z and bring it back with fg), if there are any;
  • the number of attached running jobs (commands started with a &), if there are any;
  • a pair of square brackets, in blue if your current shell is running in a terminal multiplexer (screen or tmux);
  • the current user, in bold yellow if it is root, in light white if it is not the same as the login user;
  • a green @ if the connection has X11 support, a yellow one if not;
  • the current host, if you are connected via a telnet connection (in bold red) or SSH (either a blue hostname or different colors for different hosts);
  • a green colon if the user has write permissions on the current directory, a red one if he has not;
  • the current directory in bold, shortened if it takes too much space, while preserving the first two directories;
  • the current Python virtual environment, if any;
  • an up arrow if an HTTP proxy is in use;
  • the name of the current branch if you are in a version control repository (git, mercurial, subversion, bazaar or fossil), in green if everything is up to date, in red if there are changes, in yellow if there are pending commits to push;
  • the number of added/deleted lines (git) or files (fossil), if changes have been made and the number of pending commits, if any;
  • a yellow plus if there is stashed modifications;
  • a red star if there is some untracked files in the repository;
  • the error code of the last command, if it has failed in some way;
  • a smart mark: ± for git directories, ☿ for mercurial, ‡ for svn, ‡± for git-svn, ⌘ for fossil, $ or % for simple user, a red # for root;
  • if you ask for, the liquidprompt will be replicated in your terminal window's title (without the colors);

You can temporarily deactivate the liquid prompt and come back to your previous one by typing prompt_off. Use prompt_on to bring it back. You can deactivate any prompt and use a single mark sign ($ for user and # for root) with the prompt_OFF command.


Installation is simple. The basic dependencies are standard available on Unix. Please check if they are met if you experience some problems during the installation. See the DEPENDENCIES section for what you need.

Follow these steps:

cd ~/ git clone source liquidprompt/liquidprompt

To use it everytime you start a shell add the following line to your .bashrc (if you use bash) or .zshrc (if you use zsh):

source ~/liquidprompt/liquidprompt

Next up is the configuration, you can skip this step if you already like the defaults:

cp ~/liquidprompt/liquidpromptrc-dist ~/.config/liquidpromptrc

You can also copy the file to ~/.liquidpromptrc. Use your favorite text editor to change the defaults. The liquidpromptrc file is richly commented and easy to set your own defaults. You can even theme liquidprompt and have a custom PS1. This is explained in the sections below.

Please do not edit or set the PROMPT_COMMAND variable, or else the prompt will not be available.


Apart from obvious ones, some features depends on specific commands. If you do not install them, the corresponding feature will not be available, but you will see no error.

  • battery status needs acpi.
  • temperature status needs lm-sensors.
  • detached sessions is looking for screen and/or tmux.
  • VCS support features needs… git, hg, svn or fossil, but you knew it.

For other features, the script uses commands that should be available on a large variety of unixes: tput, grep, awk, sed, ps, who.


You can configure some variables in the ~/.liquidpromptrc file:

  • LP_BATTERY_THRESHOLD, the maximal value under which the battery level is displayed
  • LP_LOAD_THRESHOLD, the minimal value after which the load average is
  • LP_TEMP_THRESHOLD, the minimal value after which the temperature average is displayed
  • LP_PATH_LENGTH, the maximum percentage of the screen width used to display the path
  • LP_PATH_KEEP, how many directories to keep at the beginning of a shortened path
  • LP_HOSTNAME_ALWAYS, choose between always displaying the hostname or showing it only when connected with a remote shell
  • LP_USER_ALWAYS, choose between always displaying the user or showing it only when he is different from the logged one

You can also force some features to be disabled, to save some time in the prompt building:

  • LP_ENABLE_PERM, if you want to detect if the directory is writable
  • LP_ENABLE_SHORTEN_PATH, if you want to shorten the path display
  • LP_ENABLE_PROXY, if you want to detect if a proxy is used
  • LP_ENABLE_JOBS, if you want to have jobs informations
  • LP_ENABLE_LOAD, if you want to have load informations
  • LP_ENABLE_BATT, if you want to have battery informations
  • LP_ENABLE_GIT, if you want to have git informations
  • LP_ENABLE_SVN, if you want to have subversion informations
  • LP_ENABLE_HG, if you want to have mercurial informations
  • LP_ENABLE_BZR, if you want to have bazaar informations
  • LP_ENABLE_FOSSIL, if you want to have fossil informations
  • LP_ENABLE_VCS_ROOT, if you want to show VCS informations with root account
  • LP_ENABLE_TITLE, if you want to use the prompt as your terminal window's title
  • LP_ENABLE_SCREEN_TITLE, if you want to use the prompt as your screen window's title
  • LP_ENABLE_SSH_COLORS, if you want different colors for hosts you SSH in
  • LP_ENABLE_TIME, if you want to display the time at which the prompt was shown
  • LP_TIME_ANALOG, when showing time, use an analog clock instead of numeric values

Note that if required commands are not installed, enabling the corresponding feature will have no effect. Note also that all the LP_ENABLE_… variables override the templates, i.e. if you use $LP_BATT in your template and you set LP_ENABLE_BATT=0 in your config file, you will not have the battery informations.

If you are using bash and want to use the PROMPT_DIRTRIM built-in functionality to shorten but still have liquidprompt calculating the number of directories to keep in the path, precise a value for PROMPT_DIRTRIM before sourcing liquidprompt and liquidprompt will override this value with one fitting the width of your terminal.

You may face performances decrease when using VCS located in remote directories. To avoid that, you can set the LP_DISABLED_VCS_PATH variable to a list of absolute and colon (":") separated paths where VCS-related features will be disabled.



You can prefix the LP_PS1 variable with anything you want using the LP_PS1_PREFIX. The following example activate a custom window's title:

LP_PS1_PREFIX="\[\e]0;\u@\h: \w\a\]"

To postfix the prompt, use the LP_PS1_POSTFIX variable. For example, to add a newline and a single character:


Note: the prompt_tag function is convenient way to add a prefix. You can thus add a keyword to your different terminals:

[:~/code/liquidprompt] develop ± prompt_tag mycode
mycode [:~/code/liquidprompt] develop ±


You can sort what you want to see by sourcing your favorite template file (*.ps1) in the configuration file.

You can start from the liquid.ps1 file, which show the default settings. To use your own configuration, just set LP_PS1_FILE to your own file path in your ~/.liquipromptrc and you're done.

Those scripts basically export the LP_PS1 variable, by appending features and theme colors.

Available features:

  • LP_BATT battery
  • LP_LOAD load
  • LP_TEMP temperature
  • LP_JOBS detached screen or tmux sessions/running jobs/suspended jobs
  • LP_USER user
  • LP_HOST hostname
  • LP_PERM a colon ":"
  • LP_PWD current working directory
  • LP_PROXY HTTP proxy
  • LP_VCS informations concerning the current working repository
  • LP_ERR last error code
  • LP_MARK prompt mark
  • LP_TITLE the prompt as a window's title escaped sequences
  • LP_BRACKET_OPEN and LP_BRACKET_CLOSE, brackets enclosing the user+path part

For example, if you just want to have a liquidprompt displaying the user and the host, with a normal full path in blue and only the git support:

export LP_PS1=`echo -ne "[\${LP_USER}\${LP_HOST}:\${BLUE}\$(pwd)\${NO_COL}] \${LP_GIT} \\\$ "`

Note that you need to properly escape dollars in a string that wil be interpreted by bash at each prompt.

To erase your new formatting, just bring the LP_PS1 to a null string:

 export LP_PS1=""


You can change the colors and special characters of some part of the liquid prompt by sourcing your favorite theme file (*.theme) in the configuration file.

Liquid prompt is distributed under the GNU Affero General Public License version 3.

  • Does not display the number of commits to be pushed in Mercurial repositories.
  • Browsing into very large subversion repositories may dramatically slow down the display of the liquid prompt (use LP_DISABLED_VCS_PATH to avoid that).
  • Subversion repository cannot display commits to be pushed, this is a limitation of the Subversion versionning model.
  • The proxy detection only uses the $http_proxy environment variable.
  • The window's title escape sequence may not work properly on some terminals (like xterm-256)
  • The analog clock necessitate a unicode-aware terminal and a sufficiently complete font.
