bash read loop and zero-ing scrip

#!/bin/bash
[[ $1 == -0 ]] && { shift ; while read -d $'\0' -r I ; do eval "$1" ; done ; } || { while read -r I ; do eval "$1" ; done ; }


#!/usr/bin/env -S perl -p
chomp ; $_.="\0"

# example where everything is zero ended
find -size +5M -mtime -700 -not -path "*/video_backup/*" -group nadim -print0 | \

-n -0 'exiftool "$I" | grep -i rotation | grep -q 0 && echo "$I"'

# nothing zero ended, would work as well because none of the tool involved
# split on space
# zero-ing is useful when tools like xargs (see -d) split on space
