When I use GUIs, my knowledge of keyboard shortcuts coupled with
the mouse actions is no different than top gamer playing a
Sure, GUIs might not beat CLIs in terms of scriptability, but
GUIs coupled with REPLs sure do the job pretty well.
When I am on Mac OS X and Windows, reaching out for the CLI means
using developer tools only available via the console or
automating administration tasks.
On the other hand when at any other UNIX flavours besides Mac OS
X, it seems the CLI is unavoidable.
As for CLIs regaining their central place in the world of
computing, in a world going towards speech recognition and touch
interfaces, I very much doubt CLI use will increase.
