Bro can you make tutorial please. Kind request please. I need to use this script. Please
You need to have access to SSH. If you have a shared hosting then it won't work because most of them, if any don't offer terminal access with admin to the server. You must have at least a VPS and above such as a dedicated server.
Once you SSH into your server as root (or any other access with admin privileges) where the script instance is installed, you can simply follow these instructions:
CD (command to switch directory) to your website directory (usually public_html path, *e.g. cd /public_html/)
CD (command to switch directory) to Application (folder where to run the command, *e.g. cd /public_html/application)
then run the following command as sudo (admin): sudo composer update
done.
*path shown on the examples above would be different depending on your LAMP configuration.
