# treeclone - pretty much just a wrapper around cp but only for cloning the
# CONTENTS of a directory (via /. ) recursively (-a) and non-destructive (-n)
# by default. Useful for preventing disaster from forgetting -n

Study: .bashrc vs .bash_profile

On most *nix:

  • ~/.bash_profile
    • executed when type un/pw to login via console
    • executed when type un/pw to login via ssh
    • not executed when you type /bin/bash to start a new bash instance
    • not executed when open a new terminal instance unless mac os
