How do I make the ssh connection from my country only?

I tried to do this: apt install geoip-bin geoip-database

I created this script in: /usr/local/bin/

nano filter.sh

#!/bin/bash
ALLOW_COUNTRIES="SA"
if [ $# -ne 1 ]; then
  echo "Usage:  `basename $0` <ip>" 1>&2
  exit 0
fi

COUNTRY=`/usr/share/GeoIP $1 | awk -F ": " '{ print $2 }' | awk -F "," '{ print $1 }' | head -n 1`

[[ $COUNTRY = "IP Address not found" || $ALLOW_COUNTRIES =~ $COUNTRY ]] && RESPONSE="ALLOW" || RESPONSE="DENY"
if [ $RESPONSE = "ALLOW" ]
then
  exit 0
else
  logger "$RESPONSE sshd connection from $1 ($COUNTRY)"
  exit 1
fi

chmod +X filter.sh

to enable it, In /etc/hosts.deny I added:

sshd: ALL

in /etc/hosts.allow I added:

sshd: ALL: aclexec /usr/local/bin/filter.sh %a

but the problem is when I type bash filter.sh anyIP, I get /usr/share/GeoIP is a directory error.
