ffid() {
if [ -z "$@" ]
then
>&2 echo "ffid: no nickname specified!"
else
cmd=$(curl -s https://www.facebook.com/${@} | grep -o 'entity_id[^[:blank:]]*' | awk -F':' '{print $2}' | awk -F '}' '{print $1}')
if [[ -n $cmd ]]; then
echo "$cmd"
else
>&2 echo "ffid: invalid nickname. Usage: ffid <facebook nickname>"
fi
fi
}

Just run:
$ ffid <facebook nickname>
