What is the main problem someone migrating from bash to zsh should face? A few times I have had problems in bash that other using zsh didn't have and they were gloating about how smart they are. Also I have seen zsh users among people that I admire, and I have tried a couple of times half heartedly to move to zsh but every time returned because I didn't have time (and was lazy) to learn to do my routine jobs in zsh. Is there a good practical migration tool around? or are there some important things you would recommend that I learn to make the transition easier, at least so that I can try it and see if it makes any difference "for me"? by the way I spend most of my life on mac, ubuntu and RedHat variants.

While they are similar (more similar than Bash and Tcsh, for example) they are different enough to force you to read documentation before doing nontrivial configuration.

It is not hard at all to start using it though, just grab someone's .zshrc and modify it to suit your taste.
