New .bashrc-file

Previously I wrote about functions and aliases, however I just swtiched back to bash from zsh and thought I’d share some of my .bashrc-file. I also switched from TotalTerminal to iTerm 2.

LSCOLORS

Bored with the orignial colors in your bash? Try these:

export LSCOLORS=gxfxcxdxCxegedabagacad

This will set the following up:

# LSCOLORS are written as one string where each
# index (two chars) is a type from the following:
# 1.   directory
# 2.   symbolic link
# 3.   socket
# 4.   pipe
# 5.   executable
# 6.   block special
# 7.   character special
# 8.   executable with setuid bit set
# 9.   executable with setgid bit set
# 10.  directory writable to others, with sticky bit
# 11.  directory writable to others, without sticky bit
#
# Colors are defined by
# a    black
# b    red
# c    green
# d    brown
# e    blue
# f    magenta
# g    cyan
# h    light grey
# A    bold black, usually shows up as dark grey
# B    bold red
# C    bold green
# D    bold brown, usually shows up as yellow
# E    bold blue
# F    bold magenta
# G    bold cyan
# H    bold light grey; looks like bright white
# x    default foreground or background

COLORS

Before we defined our PS1 we define the colors we need. Note the RESET color, which resets the PS1 to default color.

# COLORS
RESET='\e[0m'
RED='\e[0;31m'
GREEN='\e[0;32m'
YELLOW='\e[0;33m'
BLUE='\e[0;34m'
MAGENTA='\e[0;35m'
CYAN='\e[0;36m'
WHITE='\e[0;37m'

PROMPT_COMMAND

The PROMPT_COMMAND will be run after each command. Here we can create the dynamic PS1.

Note that the PS1 is actually on one line, but wraps here

export PROMPT_COMMAND=__prompt_command

function __prompt_command() {
  local EXIT="$?"
  SCRIPTS_DIR="$HOME/.dotfiles/scripts"
  GIT_PROMPT=$SCRIPTS_DIR/git_prompt.rb

  PS1="\[${YELLOW}\]\u\[${RESET}\]@\[${CYAN}\]\H\[${RESET}\]
  \[${YELLOW}\] \$(\$GIT_PROMPT) \[${WHITE}\]\w\[${RESET}\]
  (\[${GREEN}\]\t\[${RESET}\])\n→ "

  if [ $EXIT != 0 ]; then
    PS1+="\[${RED}\]ಠ_ಠ\[${RESET}\] "
  fi
}

The git_prompt.rb script is “stolen” directly from vigo’s .dotfiles repository.

Note the Look of Disaproval (ಠ_ಠ) when the exit status isn’t 0.

Behold the bash

When all is done, it will look something like this:
