=Change wordpress site URL=

In a working wordpress site /wp-admin can help in changing site URL.  However if a wordpress site is no longer functioning because site URL has changed then use following steps to change wordpress site URL use:
# Edit wp-config.php and append
#:<pre>
#::      define('WP_HOME','http://example.com');
#::      define('WP_SITEURL','http://example.com');
#:</pre>
#:: Note that this is not ideal as this fixes the site URL and later this cannot be changed via settings page.  Updating wp_options database table option_name siteurl and home is better. 
# Search for old URL everywhere using 'grep -r old-url *' and replace using 
#:<pre>
#::      find . -type f -exec sed -i "s/old-url/new-url/g" '{}' \;
#:</pre>
#:: in all sub-folders and files recursively.
