Installation

One line install (requires git, make):

(cd /tmp && ([[ -d sexy-bash-prompt ]] || git clone --depth 1 --config core.autocrlf=false https://github.com/twolfson/sexy-bash-prompt) && cd sexy-bash-prompt && make install) && source ~/.bashrc

My colors don't look as advertised

If you are seeing a screen like this:

Bad TERM config

Then, your TERM environment variable may never have been configured. Run the script below to prefix our prompt with a TERM setup

cat > /tmp/.bash_prompt_term <<EOF
#!/usr/bin/env bash
# Determine what type of terminal we are using for \`tput\`
if [[ \$COLORTERM = gnome-* && \$TERM = xterm ]]  && infocmp gnome-256color >/dev/null 2>&1; then export TERM=gnome-256color
elif [[ \$TERM != dumb ]] && infocmp xterm-256color >/dev/null 2>&1; then export TERM=xterm-256color
fi

EOF
chmod +x /tmp/.bash_prompt_term
cat ~/.bash_prompt >> /tmp/.bash_prompt_term
cp /tmp/.bash_prompt_term ~/.bash_prompt
rm /tmp/.bash_prompt_term

Manual install

Requirements: git, make

# Clone the repository
git clone --depth 1 --config core.autocrlf=false https://github.com/twolfson/sexy-bash-prompt
# Cloning into 'sexy-bash-prompt'...
# ...
# Resolving deltas: 100% (13/13), done.

# Go into the directory
cd sexy-bash-prompt
# Install the script
make install
# # Copying .bash_prompt to ~/.bash_prompt
# cp -f ".bash_prompt" "/home/todd/.bash_prompt"
# ./install.bash
# # twolfson/sexy-bash-prompt installation complete!

# Rerun your ~/.bashrc
source ~/.bashrc
# todd at Euclid in ~/github/sexy-bash-prompt on master
# Your PS1 should now look like this!

Configuration

Behavior

Behavior can be customized with the following environment variables:

PROMPT_SHOW_ERROR_ONCE - If enabled (default), then will only show error color once per command execution
- bash persists a non-zero exit code across missing commands (e.g. comment line only, keyboard interrupt, empty command)
- Setting this to 1 (default) means show error status once, 0 means always show same error status until a new command is executed

Colors

Colors can be customized by editing .bash_prompt directly, or by setting the following environment variables:

PROMPT_USER_COLOR - Color for username (e.g. todd)
PROMPT_PREPOSITION_COLOR - Color for 'at', 'in', 'on'
PROMPT_DEVICE_COLOR - Color for machine name (e.g. Euclid)
PROMPT_DIR_COLOR - Color for directory (e.g. ~/github/sexy-bash-prompt)
PROMPT_GIT_STATUS_COLOR - Color for git branch and symbol (e.g. master)
PROMPT_GIT_PROGRESS_COLOR - Color for in progress git actions (e.g. [merge])
PROMPT_SYMBOL_COLOR - Color for prompt symbol by default or on success (e.g. $)
PROMPT_SYMBOL_ERROR_COLOR - Color for prompt symbol on error (e.g. $)

You can set colors via tput or ANSI escape codes. For example:

# Inside your `.bashrc` or `.bash_profile`
PROMPT_USER_COLOR="$(tput bold)$(tput setaf 9)" # BOLD RED
source ~/.bash_prompt

Color overridden prompt

Symbols

Similarly, symbols can be customized with the following environment variables:

PROMPT_SYNCED_SYMBOL - Symbol for clean and synced branch (e.g. empty string)
PROMPT_DIRTY_SYNCED_SYMBOL - Symbol for dirty and synced branch (e.g. *)
PROMPT_UNPUSHED_SYMBOL - Symbol for unpushed branch (e.g. △)
PROMPT_DIRTY_UNPUSHED_SYMBOL - Symbol for dirty and unpushed branch (e.g. ▲)
PROMPT_UNPULLED_SYMBOL - Symbol for unpulled branch (e.g. ▽)
PROMPT_DIRTY_UNPULLED_SYMBOL - Symbol for dirty and unpulled branch (e.g. ▼)
PROMPT_UNPUSHED_UNPULLED_SYMBOL - Symbol for unpushed and unpulled branch (e.g. ⬡)
PROMPT_DIRTY_UNPUSHED_UNPULLED_SYMBOL - Symbol for dirty, unpushed, and unpulled branch (e.g. ⬢)
PROMPT_SYMBOL - Symbol given after each prompt (e.g. $)
- By default, this is $ for normal users and # for root

# Inside your `.bashrc` or `.bash_profile`
PROMPT_UNPUSHED_SYMBOL="↑"
source ~/.bash_prompt

Symbol overridden prompt

Compatibility

In some situations, the default symbol set can be drawn incorrectly (e.g. as diamonds). To remedy that, a simpler set of symbols can be used:

PROMPT_SYNCED_SYMBOL=""
PROMPT_DIRTY_SYNCED_SYMBOL="*"
PROMPT_UNPUSHED_SYMBOL="↑"
PROMPT_DIRTY_UNPUSHED_SYMBOL="*↑"
PROMPT_UNPULLED_SYMBOL="↓"
PROMPT_DIRTY_UNPULLED_SYMBOL="*↓"
PROMPT_UNPUSHED_UNPULLED_SYMBOL="*↑↓"
PROMPT_DIRTY_UNPUSHED_UNPULLED_SYMBOL="*↑↓"

How does it work?

bash provides a special set of variables for your prompts. PS1 is the one used by default. The install script adds a command to ~/.bashrc, a file that is run every time a new terminal opens. Inside of the new command, we run our script and set your PROMPT_COMMAND and PS1 which runs some git commands to determine its current state and outputs them as a string.

Support

Linux and Mac OSX are supported platforms.

Windows is supported to the best of my abilities. However, there have been font issues with using PuTTY.

Uninstallation

To uninstall sexy-bash-prompt, perform the following steps:

Remove . ~/.bash_prompt from ~/.bashrc
Delete ~/.bash_prompt (e.g. rm ~/.bash_prompt)
During installation, we may have added a . ~/.bashrc invocation to ~/.bash_profile, ~/.bash_login, or ~/.profile
- Feel free to remove this if it's no longer necessary
