[Help-bash] read -r question

[Leonardo Nc]

Hi, I'll like to know what these lines mean. It is a part of the function
load_profile() in the arch linux file /usr/lib/network/globals

while read -r hook; do
    source "$hook"
    done < <(find -L "$PROFILE_DIR/hooks" -maxdepth 1 -type f -executable
-not -name '.*' -not -name '*~' | sort -u)

at the beginning of the function is declared a local variable called hook
with the line "locale hook".

thanks for you help.
