Short PWD

# Spit out a shortened working directory
#
# I tried out the fish shell (http://ridiculousfish.com/shell/) recently
# after it showed up on Hacker News, and the part I really liked was the 
# shortened working directory on the prompt:
#
#     dave@lew ~/w/g/transport>
#
# Here's a first cut at making it work for bash.

function short_pwd {
    echo $PWD | sed "s:${HOME}:~:" | sed "s:/\(.\)[^/]*:/\1:g" | sed "s:/[^/]*$:/$(basename $PWD):"
}
