On every machine that I install, I need a custom environment. At the very basic, I need screen and bash customizations. I will attempt to keep this blog post up-to-date with my most recent config.

/etc/bash.bashrc_halfgaar (naming scheme depends on distro): 

prompt_command {
  XTERM_TITLE="\e]2;\u@\H:\w\a"
 
  BGJOBS_COLOR="\[\e[1;30m\]"
  BGJOBS=""
  [ "$(jobs | head -c1)" ]; BGJOBS=" $BGJOBS_COLOR(bg:\j)";
 
  DOLLAR_COLOR="\[\e[1;32m\]"
  [[ ${EUID} == 0 ]] ; DOLLAR_COLOR="\[\e[1;31m\]";
  DOLLAR="$DOLLAR_COLOR\\\$"
 
  USER_COLOR="\[\e[1;32m\]"
  [[ ${EUID} == 0 ]]; USER_COLOR="\[\e[41;1;32m\]";
 
  PS1="$XTERM_TITLE$USER_COLOR\u\[\e[1;32m\]@\H:\[\e[m\] \[\e[1;34m\]\w\[\e[m\]\n\
$DOLLAR$BGJOBS \[\e[m\]"
} PROMPT_COMMAND=prompt_command
 EDITOR=vim
 ls='ls --color=auto' ll='ls -l' lh='ls -lh' grep='grep --color=auto'

Don’t forget to source the file in ~/.bashrc

~/.screenrc: 

caption always "%{= kB}%-Lw%{=s kB}%50>%n%f* %t %{-}%+Lw%<"
vbell off
startup_message off
term linux
