I have a MediaWiki 1.32.0 website which I want to upgrade, hosted on a CentOS "Shared Server" environment.

It is an all-core website with no added extensions, skins and images (besides logo)

To upgrade I need to change generally all files in the website's directory to those inside a directory of a newer version's MediaWiki installment (available inside a tartball) by a general overriding operation.

To download a latest MediaWiki tarball containing such directory (as of 13/08/19) one could execute:

wget https://releases.wikimedia.org/mediawiki/1.33/mediawiki-1.33.0.tar.gz

In my existing website directory, there are these files I already edited and shouldn't override:

1. LocalSettings.php


2. robots.txt


3. .htaccess


4. 
   example.com.png (logo image)


5. 
   googlec69e044fede13fdc.html (Google search console verification file)

How could I download, and extract all files from directory in tarball to override a my current MediaWiki directory to override all files besides listed exceptions (such as the files listed above)?
_{I do plan to backup the old directory before changes manually as priming part of the script; adding a condition to continue only of the backup was done might be a nice idea; all of this, aside from having automatic daily backups).}

Create a file exclude.me

LocalSettings.php

robots.txt

.htaccess

example.com.png

googlec69e044fede13fdc.htm

Extract the archive

tar xvzf mediawiki-1.33.0.tar.gz --exclude-from=exclude.me --strip-components 1 -C /path/to/your/wiki

see https://unix.stackexchange.com/a/419400/364705 and https://stackoverflow.com/a/30259783

But if this is a production server with important data, I'd still suggest going the way terdon described.
And maybe just symlink the extracted archive to where your mediawiki is --the old-fashioned unix-way.

Extracting the tarball you have in your question will create the directory mediawiki-1.33.0 which contains the following sub-directories:

$ tree -dL 1 mediawiki-1.33.0

mediawiki-1.33.0

├── cache

├── docs

├── extensions

├── images

├── includes

├── languages

├── maintenance

├── mw-config

├── resources

├── skins

├── tests

└── vendor



12 directories

Assuming these are also the directories you need in a proper mediawiki installation, all you need to do is:

1. 
   

   Backup the files you want to keep, using -p to keep the permissions, ownership and timestamps unchanged.

   
   
   

   cp -p LocalSettings.php robots.txt .htaccess example.com.png googlec69e044fede13fdc.html /some/other/path
   
   

   
   


2. 
   

   Extract the tarball

   
   
   

   tar xvzf mediawiki-1.33.0.tar.gz
   
   

   
   


3. 
   

   Copy the files to wherever they should be

   
   
   

   cp -ra mediawiki-1.33.0/* /path/to/mediawiki/instrallation
   
   

   
   
   

   This will overwrite any existing files.

   
   


4. 
   

   Copy the backups back to their original locations

   
   
   

   cp -p /some/other/path/LocalSettings.php /original/path
