I often run local sites from a projects folder that is stored in a dropbox folder the full path is long, so instead of using the full path I create an alias in temrinal which is a shortcut to that path. This means instead of typing:
cd ~/"Dropbox (Personal)/projects
I can type:
To do this open your bash profile:
Then create the alias:
#alias alias projects='cd ~/"Dropbox (Personal)/projects"'
Restart terminal then type your shortcut and press enter to be taken to the alisd location.
Aliases are really useful and simple to setup.
