Are you a lazy developer like me? Would you go to great medium lengths merely to save a few keystrokes? My awesome devops friend Dopamine taught me this little ditty. In the .bashrc file, include an alias to source your common shell logins like so:

alias sauce='source ~/.bashrc; source ~/.bash_aliases; source ~/.profile;'

You may need to adjust for your distribution and usage, but now you can lazily source your new aliases and get lost in the sauce!
