time management and bash

Sometimes very small things give a very tangible effect. So tangible that the sensations made Firefox install and share it with the public. Recently I started using this PS1:

PS1='\D{%H.%M} \u@\h \w\n\$ '

Or with coloring:

PS1='\[\033[02;34m\]\D{%H.%M} \u@\h\[\033[00m\] \w\n\$ '

As a result, the brain begins to receive information about how much time and what kind of activity is spent during work. That helps a lot (imho, even on a purely subconscious level) to more efficiently allocate your time. And, what is valuable with this approach to business, time tracking does not distract from production. Unlike specialized solutions in the form of a beautiful web-2.0 or a charming GUI, where you need to consciously take care of yourself with your own hands. In addition, you can immediately see a lot of lines with information about your activity and keep a session log without problems. Vobschem here.

PS This, by the way, is one of those features that is only possible in the command-line interface. And it is not clear why the supporters of WIMP and CL will not get together somehow and will not choose the best of the two approaches, and will not mix everything in convenient proportions?

PPS For newbies to bash: PS1 is best set in $ HOME / .bashrc
