generating self signed SSL certifcate, permissions error (OSX) -

i'm following this tutorial. i've got dnsmasq working getting permissions error when trying generate self-signed certificate using script:

#!/usr/bin/env sh cat > openssl.conf <<-eof   [req]   distinguished_name = site_distinguished_name   x509_extensions = v3_site   prompt = no   [site_distinguished_name]   cn = *.${pwd##*/}.dev   [v3_site]   keyusage = keyencipherment, dataencipherment   extendedkeyusage = serverauth   subjectaltname = @domains   [domains]   dns.1 = *.${pwd##*/}.dev   dns.2 = ${pwd##*/}.dev eof openssl req -new -newkey rsa:2048 -sha256 \   -days 3650 -nodes -x509 -keyout site.key \   -out site.crt -config openssl.conf 

here's i'm getting in terminal

project_directory $ ./ssl_cert_gen.sh -bash: ./ssl_cert_gen.sh: permission denied  project_directory $ sudo ./ssl_cert_gen.sh password: sudo: ./ssl_cert_gen.sh: command not found 

am way off? ideas? in advance.

you have make script executable:

$ chmod +x ssl_cert_gen.sh 

all executable files in unix must have corresponding executable (x) bit set, otherwise kernel won't execute them. scripts executables too, utilise "shebang" mechanism (#!) specify name of interpreter.
