Fuzzy find with per-directory frecency (using fd, fzf, fre)

fdz-dir

#!/bin/dash

set -o errexit
set -o nounset

fd_in=$PWD
fzf_height="--height 15"

if test $# -gt 0; then
    for arg in "$@"; do
        # -f for fullscreen
        if test "$arg" = "-f"; then
            fzf_height=""
        else
            # Latter args overwrite
            fd_in=$arg
        fi
    done
fi

# Default store location is ~/.local/share/fre/
store_name=$(echo "dir:$fd_in" | md5sum | awk '{print $1}')

fzf_result=$({
    fre --sorted --store_name "$store_name"
    fd -t d --follow "" "$fd_in"
} | awk '!x[$0]++' | fzf +m --reverse $fzf_height --tiebreak=index)

if test -n "$fzf_result"; then
    fre --add "$fzf_result" --store_name "$store_name" && echo "$fzf_result"
fi

awk '!x[$0]++' trick is to avoid sort | uniq, see https://stackoverflow.com/questions/11532157/remove-duplicate-lines-without-sorting
