If not, what is it, and how to get a directory or folder size in Linux? + +This is the default size, which is used to store the meta information of the directory on the disk. + +There are some applications on Linux to **[get the actual size of a directory][2]**. + +But the disk usage (du) command is widely used by the Linux administrator. + +I will show you how to get folder size with various options. + +### What’s du Command? + +**[du command][3]** stands for `Disk Usage`. It’s a standard Unix program which used to estimate file space usage in present working directory. + +It summarize disk usage recursively to get a directory and its sub-directory size. + +As I said, the directory size only shows 4KB when you use the ls command.
