I'll change it to: statfs [ -c ] [ -g ] [ -s ] Report selected statistics on the filesystem where the current file resides. The default behavior is to enable all three reporting options: -c Display XFS_IOC_FSCOUNTERS summary counter data. -g Display XFS_IOC_FSGEOMETRY filesystem geometry data. -s Display statfs(2) data.
