Intelligent cd

cd.sh

# /usr/bin/env sh

# You've heard of exa/lsd, sd and fd. But what about a modern cd?
# This isn't really it. Try autojump/z/fasd?
# But maybe this does make plain old cd 5% better, on a good day?

# Description: Just a vaguely intelligent cd
# Specifically it can handle cd'ing to a path even if it has a filename 
# at the end, in which case it cd's to the directory which contains it
