People are obsessed with command line tools because they offer the most basic interface, which is not likely to change. One of the commonly cited programming aphorisms is to "Program to an 'interface', not an implementation." Learning a GUI tool is usually easier in the short term, but becomes less flexible in the long run. As you become an increasingly skilled developer you realized that you gain order of magnitude more productivity by working at increasingly higher levels of automation and abstraction. This can be very difficult with a graphical interface since it would likely take much more work to create an adapter which will allow your code to work with the GUI interface than a command line one. GUIs are also likely to be complex and thus have the potential for bugs and performance costs.
