I face disk space full issue in Linux. When checked with df command I found the '/' directory is occupying 100%. So to check which folders consume much space I ran cd \ and du -sh. But it takes forever to run the command. But ultimately I want to get the details on which top immediate sub folders of '/' folder are consuming huge disk space. So can any one tell the command for the same.
