Grepping disk usage for biggest folders

Finding where was free space gone and who that guy that should be cleared on a server can be a challenge
Unix as I know has no usable UI tools for that, but there is a console that has power.
How to find folders for cleanup on Unix/Linux/Ubuntu?
Here is a command for grepping folders/files that has Gigabytes of size

du -c -h | grep -P "G\t"

The same for Megabytes as well, but I guess not so usable at admin level, mostly good for user folders.

du -c -h | grep -P "M\t"

And here is a sample output for the first command

MYSQL fix duplicates saving duplicated data with new id

DROP PROCEDURE `max_wid`;
DELIMITER ;;
CREATE PROCEDURE `max_wid` (OUT `y` int)
SQL SECURITY INVOKER
BEGIN
SELECT MAX(wid) into y from works;
END;;
DELIMITER ;
DELIMITER ;;
CREATE PROCEDURE `first_dup` (OUT `t` int)
SQL SECURITY INVOKER
BEGIN
SELECT wid into t FROM works GROUP BY wid HAVING ( COUNT(wid) > 1 ) LIMIT 0,1;
END;;
DELIMITER ;

The procedure itself - finding first duplicated data - and updating it to maximum possible id
After running this code till ZERO duplicates just create unique Primary key for Your table
