I want to restrict uploading for group of the users via squid. So I've choosen to use external_acl_type but after reload of the squid it returns error.

WARNING: Cannot run '/usr/local/etc/squid/lists/newupload.sh' process.

Permissions of newupload.sh and squid are the same. newupload.sh is executive.

How can I solve this problem? Thnx in advance.

newupload.sh

#!/bin/sh
while read line; do
    set -- $line
    length=$1
    limit=$2
    if [ -z "$length" ] || [ "$length" -le "$2" ]; then
      echo OK
    else
      echo ERR
    fi
done 

Strings from squid.conf

external_acl_type request_body protocol=2.5 %{Content-Lenght} /usr/local/etc/squid/lists/newupload.sh
acl request_max_size external request_body 5000
http_access allow users request_max_size

Squid version

squid -v
