.profile in Mac OS X?

I have set my terminal preferences to execute:

 set -o vi 

at startup. The problem is I don't get that command executed when open a new terminal tab.

Is there something like .profile in OS X where I can put that command?

Solution 1:

The .profile file in MacOSX works exactly how you would expect. Simply create the .profile file in your user directory if it doesn't exist.

Solution 2:

Because, as noted, Terminal has used bash by default for a few versions, you may want to keep an eye out for a .bash_profile file if .profile isn't present. See the "which startup files are read by the shell?" FAQ at http://hayne.net/MacDev/Notes/unixFAQ.html#shellStartup which explain how the different files are used and the order in which they're read at startup.
