Just `find . -type d | fzf` to determine what dir to change to (or ~ for "anywhere else")

1. Make an alias fcd 2. Make a tab complete that does that for the command fcd

This is kind of 101 bash - just DIY.

Here's mine:

(2) is the hardest part - just write something that works with `complete` and fzf. Nowadays this is childs play for any AI to just spit out.

    fz_comp()
    {
      COMPREPLY=()
      local cur="${COMP_WORDS[COMP_CWORD]}"
      local prev="${COMP_WORDS[COMP_CWORD-1]}"
      local opts="none"
      if [ -z "$cur" ];then
        COMPREPLY=($(find $1 -type d | fzf --preview="ls {} -l"))
        return
      fi
      COMPREPLY=($(find $1 -type d | grep $cur | fzf --preview="ls {} -l"))
    }

    alias fcd=cd
    _fcd(){ fz_comp $(pwd) }
    complete -F _fcd fcd
