Bash enhanced 'cd' replacement
# Replace cd functionality to use pushd instead. If file is given, open in default editor.
# You can define an array of keyword-based pre-defined directories which will work anywhere
# Examples:
# "cd bin" will take you to ~/bin/
# "cd logs" will take you to /var/log/apache2/
# Setup:
# Inside your script, define them in this manner:
# cd_array=(
# 'bin'='/root/bin'
# 'www'='/var/www'
# 'logs'='/var/log/apache2'
# 'apache'='/etc/apache2/sites-available'
# )

elif [[ "$1" =~ ^\-+$ ]]; then
# support multiple dashes and go back through dir stack for each one
bd ${#1} 1>/dev/null
elif [[ -d "$1" ]]; then
pushd "$1" 1>/dev/null
# If an array called $cd_array is defined, loop through it and check for shortcuts
# matching $1 to jump to a pre-defined location instead

# TODO: enhance with fzf

# Add a "back directory" function to change back (with popd) any number of directories
