Tuji decided to start using the Fish Shell. It's really nice!!! It is just so much more regular than the good old bash. When one does not use shell often, it is easy to forget all the caveats and stuff. Need to end a if block with fi? Well, I can remember this one. How do I redirect stderr? I think with fish I can save many trips to stackoverflow.
With modern machines, conservation of resource is no longer the top priority, rather reducing frustration/having a comfortable life is. Fish shell has great completion and discovery without the need to fiddle with configuration. I think it is designed for people like me who needs to fire up a shell from time to time to run a quick script.
