# Bash support for Zsh like chpwd hook
Implemented based on the description from
<http://zsh.sourceforge.net/Doc/Release/Functions.html#Hook-Functions>
## Usage
1. load `function.sh` and `load.sh`, eg:
source chpwd/functions.sh
source chpwd/load.sh
2. add the hook - replace `_hook_name` with your function name:
export -a chpwd_functions # define hooks as an shell array
[[ " ${chpwd_functions[*]} " == *" _hook_name "* ]] || # prevent double addition
chpwd_functions+=(_hook_name) # finally add it to the list
