Very often I have to implement console scripts (because of my laziness, for boring processes optimization). Many of them write some information to the output, show process status or display results of work. Anyway, it’s very wearisome action to read script output, and I want to highlight most important things: errors in red, successfully finished steps in green color, etc. And it is a case when ANSI escape sequences could help. They are supported by the most terminals, including VT100 (btw, Windows NT family console does not support it, but I will back to this issue later).
