Stackscript not working properly - copy and paste code is ok

Hi,

I have a stackscript I am working on, and if I copy and paste the lines one by one it works flawlessly but if I run it as a script the patching of php with php-fpm (see below) doesn't seem to work - no errors, it looks like it is fine (as in the output says patched okay) but when it tries to configure php it says unknown option –with-fpm.

i'm stumped - surely if it works copying and pasting line by line it must work as a script?

Script is below:

#!/bin/bash

apt-get update
apt-get -y install locales
dpkg-reconfigure locales
apt-get -y upgrade

echo "console-setup console-setup/charmap select UTF-8" | debconf-set-selections

# General requirements etc
apt-get -y install wget build-essential libpcre3 libpcre3-dev libssl-dev libtool libltdl3-dev libgd2-xpm-dev libmcrypt-dev libxml2-dev libmysqlclient15-dev flex m4 gawk automake autoconf bison make libbz2-dev libpcre3-dev libssl-dev zlib1g-dev re2c libssl-dev libcurl3 libcurl4-openssl-dev unzip
