Redirect subdomain URL path to main domain (and keeping exact URL path)

Most solutions posted only redirect to the the domain, not with full path.

You’d want to do this: https://halfelf.org/2012/htaccess-anarchy/

RewriteCond %{HTTP_HOST} ^blog\.example\.com  [NC]
RewriteRule ^(.*) https://example.com/$1 [L,R=301]

That looks good, but it doesnt appear to be applying. I guess there is clash in htaccess(?). Could someone let me know where the above lines should fit in, I would be grateful. I am “googled out” on this problem ??

This is my current file.

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# uploaded files
RewriteRule ^files/(.+) wp-includes/ms-files.php?file=$1 [L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule . index.php [L]
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

<IfModule mod_security.c>
 SecFilterEngine Off
 SecFilterScanPOST Off
</IfModule>

Well there’s problem one. You didn’t follow the directions of ‘replace’ the .htaccess….

RewriteCond %{HTTP_HOST} ^blog\.example\.com  [NC]
RewriteRule ^(.*) https://example.com/$1 [L,R=301]

# BEGIN WordPress
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# uploaded files
RewriteRule ^files/(.+) wp-includes/ms-files.php?file=$1 [L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule . index.php [L]
# END WordPress

<IfModule mod_security.c>
 SecFilterEngine Off
 SecFilterScanPOST Off
</IfModule>

That was current htaccess without any edit – I just wasn’t sure where to put those lines. Thankyou so much, very appreciated ?? It works! And I learned a little more about rewrites, so no bad thing
