apache - .htaccess: Redirect root url to subdirectory, but retain root url -

i in process of cleaning domain's directory structure (woe me setting root url's content in root directory!) , need insight on how use rewriterule correctly.

the gist

i want domain.tld use domain.tld/subdirectory/ still appear domain.tld in url.

my .htaccess far

options +followsymlinks rewriteengine on  #force removal of wwww subdomain rewritebase / rewritecond %{http_host} ^www.domain.tld rewriterule ^(.*)$ http://domain.tld/$1 [r=301,l]  #trailing slash rewriterule ^/*(.+/)?([^.]*[^/])$ http://%{http_host}/$1$2/ [l,r=301]  #redirect root url subdirectory redirectmatch 301 ^/subdirectory/$ http://domain.tld/ rewriterule ^/$ /subdirectory/?$ [l] 

the redirectmatch works great. unfortunately, t seems last rewriterule there should work enough, doesn't. old content setup in root directory still appears.

what missing here?

update: resolved

simple fix not experienced enough .htaccess / apache able explain why.

i had:

rewriterule ^/$ /subdirectory/?$ [l] 

removing 1 slash fixed everything:

rewriterule ^$ /subdirectory/?$ [l] 

so question is: why that?

try this:

rewriteengine on rewritebase /  rewritecond %{request_uri} !^/subdirectory/  # rewrites urls  # [replace "domain" actual domain,  # without tld (.com, .net, .biz, etc)] rewritecond %{http_host} ^(www\.)?domain\.  # rewrite subdirectory rewriterule ^(.*)$ /subdirectory/$1 [l]
