Http://blog.csdn.net/newjueqi/article/details/7054582

The DF command is used to view the file system by disk partition in Linux. You can add parameters to view the remaining disk space. The command format is as follows:

DF-Hl

Display format:

File SystemCapacity in use available % mount point

FilesystemSize used avail use % mounted on

/Dev/hda245g19G24g 44%/

/Dev/hda1494 m19 m 450 m4%/boot

/Dev/hda64.9g 2.2g 2.5g 47%/home

/Dev/hda59.7g 2.9g 6.4g 31%/OPT

/Dev/hda39.7g, 7.2g, 2.1g, 78%/usr/local

/Dev/hdb275g75g0 100%/

/Dev/hdb275g75g0 100%/

The preceding output is used as an example to indicate:

HD hard disk interface second hard disk (B), second partition (2), capacity is 75g, 75g used, available is 0, so the utilization is 100%, mounted to the root partition directory (/).

The following is an explanation of the relevant commands:

DF-Hl view the remaining disk space

DF-H: view the partition size of each root path

Du-SH [directory name] returns the directory size

Du-Sm [Folder] returns the total number of MB in this folder.
