Quick tip how to add rvm gemset name to PS1 prompt.
Put
rvm_ps1_indicator()
{
command -v rvm-prompt >/dev/null 2>&1 && test -n "$(rvm-prompt g)" && printf "(%s) " "$(rvm-prompt)"
}
PS1='\[\033[01;36m\]\u\[\033[01;35m\]@\h\[\033[01;34m\] \w \e[01;31m\]$(rvm_ps1_indicator)\[\e[m\]\$\[\033[00m\] '
in ~/.bashrc right after the loading rvm:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
Reload ~/.bashrc file (or reopen a shell) and navigate to any directory with .ruby-gemset file inside - you should get gemset name displayed like on this screenshot
