linux to view this directory folder size

du -h --max-depth=1 

 If the current directory files and folders a lot, use the command without parameters du, space can be recycled lists all the files and folders to be used. This is what is right to see that place too much is bad, so you have to specify the depth of directory layers, parameters: - max-depth =, this is a very useful parameter
