# Description: Navigate to directory using jump/autojump/zoxide/z
#
# Dependencies:
#   - jump - https://github.com/gsamokovarov/jump
#   - OR autojump - https://github.com/wting/autojump
#   - OR zoxide - https://github.com/ajeetdsouza/zoxide
#   - OR z - https://github.com/rupa/z (z requires fzf)
#   - OR z (fish) - https://github.com/jethrokuan/z (z requires fzf)
#   - OR z.lua - https://github.com/skywind3000/z.lua (z.lua can enhanced with fzf)
#
# Note: The dependencies STORE NAVIGATION PATTERNS
#
# to make z.lua work, you need to set $NNN_ZLUA to the path of script z.lua
#
# Shell: POSIX compliant
# Authors: Marty Buchaus, Dave Snider, Tim Adler, Nick Waywood
