How to create a bash alias on OS X? I want to create a bash alias on OS X, because I need to type on a really large command.

I've found some answers about the same issue on ubuntu, like this one, but they mention the ~/.bashrc file, which doesn't exist (at least by default) on OS X.
I've found that I can do this by editing the .bash_profile file.

Just added:

alias my_alias='cd /my/really/long/long/path

to .bash_profile, and after reopening bash my alias command worked just fine.
