GitX - How do you view a single file's commit history?

Question

Using GitX, how do I view the revision history for a single file? (using the command-line interface preferably)

E.g using GitK this is rather simple;

$ gitk app/models/activity.rb

Answer 1

Same way, but with gitx instead:

$ gitx app/models/activity.rb

Note that all the commits shown will include the specified file, but the full commit will be shown (i.e., it'll show changes for other files modified in that commit).
