Usage Guidelines
-
The du command is used to obtain the disk usage of a file rather than a directory.
-
The value of file must be the file name. It cannot contain the directory where the file is located.
Note
Currently, the shell does not support this command. mksh supports it. To switch to mksh, run cd bin and ./mksh.
Example
Run du -h testfile.
Output
Disk space occupied by testfile.
OHOS:/$ du -h testfile
