The first matching rule applies, so include .htaccess before excluding .*.
rsync -avP --include=".htaccess" --exclude=".*" . user@server:/dir
This copies .htaccess at every level. I don't know what you intended with ./.htaccess; if you want to match a file at the root of the copy only, start the pattern with a /. If you only want the root .htaccess, you can't just use --include='/.htaccess' --exclude='.*', because the non-rooted rule actually takes precedence here, you need to do something more complicated:
rsync -avP --exclude='/*/**/.htaccess' --include='.htaccess' --exclude=".*" . user@server:/dir

--includefirst, but the "./" in front of the "./.htaccess" was what was killing it. – Rich Apr 11 '11 at 18:26.htaccessfile, you'll have to--include='.*/'(I think) before the final--exclude, see also here – Tobias Kienzler Nov 19 '12 at 14:47rsync -avP --exclude=/.htaccess src/dir/ dst/dir/works as expected (excludes.htaccessonly at the root directory), butrsync -avP --exclude=/.htaccess src/dir dstdoesn't (it fails to exclude even at the root)? – haridsv Mar 02 '21 at 13:53src/dirand you're copying the root, sosrc/dir/.htaccessis excluded.
