quickly make bash readable

sometimes we get a shell that doesn’t look great for reading. here’s how to make them look great:

test -r ~/.dircolors && eval "$(dircolors -b ~/.dircolors)" || eval "$(dircolors -b)"
alias ls='ls --color=auto'
export PS1="\n \[\033[0;34m\]┌─────(\[\033[1;35m\]\u\[\033[0;34m\])─────(\[\033[1;32m\]\w\[\033[0;34m\]) \n └> \[\033[1;36m\]\$ \[\033[0m\]"
