# This contains two files.. the ls proxy and the vim proxy
# Problem I wanted to solve:
#   when working in terminal, sometimes I mistake ls with vim, or vice versa, when I
#   am inspecting a directory recursively. When this happens, I have to retype the
#   command. Yes, '!$' helps me to re-use the previous argument, but I still wish the
#   experience could be smoother.
# Solution:
#   make ls and vim interchangeable by delegating ls and vim to proxy scripts, and set
#   alias 'ls' and 'vim' to these scripts.
