INstall question - chown and chmod upon uploading to server

Set the following permissions on the SuiteCRM directory(Linux):
sudo chown -R www-data:www-data .
sudo chmod -R 755 .
sudo chmod -R 775 cache custom modules themes data upload
sudo chmod 775 config_override.php 2>/dev/null

That is what I see in the instructions to install SuiteCRM

But, 2 questions to start with:
from where is this command run? from with in the folder containing SuiteCRM?
what is the dot for at the end of the two line? Does the mean that I run the command from with in the crm folder, and the command will apply to all items from with in that folder?

Thanks

Joseph

ps. I’ve installed this before, but I just want to make sure…

yes and

yes :slight_smile:

Just be sure that the shown example user www-data is actually the proper user for your environment.

Thanks for the reminder.

I started running the commands and noticed that I did not have a cache folder. So, the command reminded me.
Do I need to create one?

In addition, I do not have the file that seems to be named in this command:
sudo chmod 775 config_override.php 2>/dev/null

Is that OK?

Thanks
