Problem / Steps to reproduce

I often want to restart fzf (or a script executing fzf) when script files change for quicker development turnaround cycles. In other cases (using make and friends) i use entr as the "watch" tool.

I do not want to reload fzf data but the whole fzf (or even a script executing fzf)

But I am unable to restart fzf using entr for some reason.

Not working example:

find . -type f | entr -a -n sh -c 'find . -type f | fzf'

I tried a lot of quirky variants for watch/reload but they all seems to me too complicated.

(quirky) working example:

touch /tmp/fzf_pid
while [[ -f /tmp/fzf_pid ]]
do 
  find . -type f | entr -dd -c -p -n -z curl localhost:6266 -d 'execute:kill $(cat /tmp/fzf_pid)' & 
  fzf --listen 6266 --bind 'start:execute-silent(echo $PPID > /tmp/fzf_pid)' --bind 'esc:cancel+execute(rm /tmp/fzf_pid)'

  [[ "$?" -eq 0 ]] && exit
done

I am sure there is a much more easier option to watch files and reload fzf on changes.

Any help is welcome :-)
