14 File space usage
No file system can hold an infinite amount of data. These commands report how much storage is in use or available, report other file and file status information, and write buffers to file systems.
| • df invocation | Report file system space usage. | |
| • du invocation | Estimate file space usage. | |
| • stat invocation | Report file or file system status. | |
| • sync invocation | Synchronize cached writes to persistent storage. | |
| • truncate invocation | Shrink or extend the size of a file. |
