Hi,
I am looking for someone that can assist me with my .sh script.
Please see script below:
The commented section is where help is required when un-commented it sets anything below it as a "string"

If any other issues are noticed in main script dump please do let me know :)

What I have tried:

    <Directory "/var/www/html/${PROJECTFOLDER}/public">
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>
EOF
)
echo "${VHOST}" > /etc/apache2/sites-available/000-default.conf

You are trying to do it too complicated. Just assign the string as it is (but escape double quotes):

VHOST="<VirtualHost *:80>
    DocumentRoot \"/var/www/html/${PROJECTFOLDER}/public\"
    <Directory \"/var/www/html/${PROJECTFOLDER}/public\">
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>
"

If you use single quotes around the entire block, you can omit the escapes for the double quotes
eg

VHOST='<VirtualHost *:80>
    DocumentRoot "/var/www/html/${PROJECTFOLDER}/public"
    <Directory "/var/www/html/${PROJECTFOLDER}/public">
        AllowOverride All
        Require all granted
    
<virtualhost>
'

That won't work as required here because it would not expand the ${PROJECTFOLDER} variables.

Thank you @Jochen_Arndt, I like your solution. I will accept it in a day or two, I would like to see if anyone else has other ways to do it.
