can’t cd into nextcloud data directory. Would like to be able to copy/move files in this directory to an external drive for backup.
To cd into the directory as sudo
Bash shell commands like “cd” can’t be “sudo’ed”, so do this:
$ sudo -i
now you can cd into the directory and do what you like.
To list all files:
You have permission issues that the users which is running your webserver has no access to this folders. If you’re on e.g. Ubuntu/Debian this can be checked by running the following command:
$ sudo -u www-data ls -la /path/to/folder
this command should return a list of files / folders instead of a “Permission denied” message.
in my case:
$ sudo -u www-data ls -la /var/www/data
