Question

I know how to find and replace a section in a config file like this:

sudo sed -i "s/upload_max_filesize = 2M/upload_max_filesize = 3M/" /etc/php5/cgi/php.ini

But how do I add a whole new section to the end of the config file within the bash script?

server {
    listen      xx.xx.xx.xx:80;                # your server's public IP address
    server_name  myapp.com;                   # your domain name
    root         /usr/share/nginx/www/myapp/;  # absolute path to your WordPress installation    
}

I tried this within the terminal echo "server { ... }" >> nginx.conf but I get a

-bash: nginx.conf: Permission denied

Not sure if this would be ok within the bash script or I would get a permission denied again…

Answer 1

You are using the right syntax.

echo "....." >> ngix.conf

Just make sure you have the correct write permissions for ‘ngix.conf’.

-bash: nginx.conf: Permission denied

This indicates that you have no write privileges.

You can also write the section in an single file like ‘new_section.txt’ and late add it with:

cat new_section.txt >> ngix.conf

However I would not advise to add configurations to ngix in this way.
You can use the ‘include’ statement.

include you_conf_path/my_new_config.conf;

This way you can group the configuration and have some small config files and not one huge file. Then you can also name your file in a way that helps you find the right one.
