Structure of .htaccess file in wordpress

When we are placing our word press site in root directory of server then .htaccess looks like

# 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

When we are placing word press in a sub directory then .htaccess looks like this

suppose my sub folder name is barraid

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