Rainbow Bash Prompt

An extension for bash that generates a rainbow-colored PS1 with IP address shown as 4 blocks of color.

Install with apt (ubuntu/debian)

Add the repository

You can add the repository by running the following command:

sudo wget -O /usr/share/keyrings/soph-deb.gpg "https://cdn.sophuwu.com/deb/key.gpg" && echo 'deb [signed-by=/usr/share/keyrings/soph-deb.gpg] https://cdn.sophuwu.com/deb/ sophuwu main' | sudo tee /etc/apt/sources.list.d/sophdeb.list

This script will do the same thing:

curl https://cdn.sophuwu.com/deb/addrepo.sh | sudo sh

Install the "bash-rb-ps1" package

sudo apt update
sudo apt install bash-rb-ps1

Run for the first time

This will only work if you are using bash with xterm-like escape sequences. You can enable the generator by running:

eval $(bash-rb-ps1 help)

If you experience an error, or want to disable the prompt, you can run:

unset PROMPT_COMMAND
PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '

To see help and other information about the command, use:

man bash-rb-ps1.1

Compile from source

make
sudo install ./build/bashprompt /usr/local/bin/bash-rb-ps1
sudo install ./releaser/bash-rb-ps1.1 /usr/local/share/man/man1/bash-rb-ps1.1

Options:

Environment variables can be set to customize the prompt.

IPCOLOR

• Controls how the IP address is printed.
• IPCOLOR="" IP address will be colored with the default color palette.
• IPCOLOR="alt" IP address will be colored with an alternate color palette.
• IPCOLOR="none" IP address will not be printed.

PWDLEN

• Controls the length of the printed working directory.
• PWDLEN=0 Full path.
• PWDLEN=1 Only the current directory.
• PWDLEN=2 Current directory and its parent.

RBPSFMT

• Controls the format of the prompt.
• Only valid format specifiers will be printed. Strings or invalid specifiers will be ignored.
• Default: "%i %? %u %l %e %d"
• Certain specifiers allow custom colours, to use them, put a number 0-255 after the % in the form fg.bg (%32.240u, %.42l, %128d).
• Format specifiers:
  • %i - IP address (4 blocks of color)
  • %? - Exit code of last command
  • %u - Username
  • %h - Hostname
  • %l - Line number
  • %e - Random emote (:D, :P, etc.)
  • %d - Current working directory (shortened according to PWDLEN)
