fish shell vs. bash

fish shell is a great tool. But it can be confusing in the initial stages especially to adapt from bash to fish shell. Some important differences are highlighted below.

1. escaping wildcards such as *
   use double quotes
   rm "*.pyc"
   
2. command expansion using backticks
   the bash command
   rm `find -type d -name .svn` would be
   rm (find -type d -name .svn) in fish shell
