If statement in my prompt?
Anyone know how I can do a simple if statement in my prompt? As it is now I run a few commands to customize my prompt using command substitution. What I would prefer is if I could change the color dependent on the results.
So `command` > output > if = 'x' then color=blue else color=red
That way I can make certain problems stand out more and draw my attention to them.
As it is I have a ridiculously complicated prompt that runs numerous commands and generate a 2 line prompt filled with useful nuggets of info.. sometimes I miss something.
