I will never learn this tool I will not even contemplate using this tool. The reason is very simple: I can trust 'grep' to be on any system I ever touch. Learning ugrep doesn't make any sense as I can't trust it to be available. I could still use it on my own systems, but I work on customer systems which won't have this tool installed. And I'm proficient enough with grep that it's 'good enough', I'm not focussing on a better grep. I'm focussing on fixing a problem, or trying something new. I'd rather invest my time into something that will benefit me across all environments I work with. Because a tool may be 'better' (whatever that means) doesn't mean it will see adoption. This is not about being closeminded, but it's about focus on what's really important.
