The results of some combinations are confusing. to sum up one of the most common methods: du-shc, -s indicates the sub-directory size.-h indicates the unit K, M, and G.-c indicates that the total is displayed at the end. assume that the directory structure is: test/dir1/dir1_1/file1.txt Test/dir2/dir2_1 Test/file.txt where the directory and file size are 4 KB (note that the directory itself has a size ), if the working directory is Test, the running result is 12 K dir1 8.0 K dir2 4.0 K test. py 24 K total can be seen that the size of dir1 is: dir1 The size of the big and small dir1_1's big and small sizes file1.txt; the size of dir2 is: the size of dir2 itself + the size of dir2_1. In addition, the final total is the sum of the first few items.
