Solved Command line fun 'n' games

I need to edit a config file in /volume1/docker/nextcloud/config so I've SSH'd in as 'nasadmin' cos I don't know the root user's password (should I?).

I want to firstly copy the config.php file as config-original.php in case it all goes wrong then edit a couple of lines.

Here's the contents of the config directory

drwxrwxrwx+ 1 33 root   300 Jun 13 23:50 .
drwxrwxrwx+ 1 33 root   412 Jun 13 23:05 ..
-rw-r--r--  1 33 root    60 Jun 13 23:05 apache-pretty-urls.config.php
-rw-r--r--  1 33 root    70 Jun 13 23:05 apcu.config.php
-rw-r--r--  1 33 root   377 Jun 13 23:05 apps.config.php
-rw-r-----  1 33   33   979 Jun 13 23:50 config.php
-rw-r--r--  1 33 root 55973 Jun 13 23:05 config.sample.php
-rw-r--r--  1 33 root   495 Jun 13 23:05 .htaccess
-rw-r--r--  1 33 root   476 Jun 13 23:05 redis.config.php
-rw-r--r--  1 33 root   674 Jun 13 23:05 reverse-proxy.config.php
-rw-r--r--  1 33 root   669 Jun 13 23:05 smtp.config.php

Maybe a side issue but the first thing that jumps out is that config.php is in the group '33' whereas every other file here - and all the other files in the other directories for the Nextcloud data are 'root'. Is this a potential problem? I don't think so but have I inadvertently changed the group?

So, I'm hard, I know how to use Terminal on me Mac. All I need say is:

nasadmin@MyNAS:/volume1/docker/nextcloud/config$ cp config.php config-original.php

But...

cp: cannot open ‘config.php’ for reading: Permission denied

So either I want to be logged in as root - in which case where do I find the password - or can I 'sudo'?

nasadmin@MyNAS:/volume1/docker/nextcloud/config$ sudo cp config.php config-original.php

What could possibly go wrong?!

Just elevate your login as root using sudo -i, enter your nasadmin pass again and you will have root access. Then continue on.

Just elevate your login as root using sudo -i

Thanks @Rusty, I also found details here in the Synology help.

Done that then! Thanks for the tip @Rusty. I then discovered there's no Nano so had to use Vi to add "nextcloud.mydomain.tld" to the Trusted Domains section.

And it works
