I would say it's definitely worth learning, even if you don't use it for coding, simply for the reason that it's ubiquitous.
I use it constantly when configuring Linux machines, which is only an ancillary part of my job, just for the regex search to find the line I want to tweak. Since servers don't generally offer a GUI, it's the simplest way to replicate that feature.
