Linux查看文件夹大小
du -sh 查看当前文件夹大小
du -sh * | sort -n 统计当前文件夹(目录)大小，并按文件大小排序
du -sk filename 查看指定文件大小
When the disk size will exceed the standard alarm, then if the master command df and du is a very wise choice.
df可以查看一级文件夹大小、使用比例、档案系统及其挂入点，但对文件却无能为力。
du可以查看文件及文件夹的大小。
Combination of the two to use, very effective. For example, to view a directory with df which is too large, then df view folders or file size, so you can quickly identify the crux.
