Administering filesystems

Displaying filesystem and directory usage statistics

In the Filesystem Manager, display disk usage statistics by selecting View Disk Space. The display changes to show (in MB):

the total amount of disk space in the filesystem
the amount of space that is currently being used
the amount of free disk space
the percentage of the filesystem that is currently being used

To display inode usage statistics, select View

Inode Usage. The display changes to show:

the total number of inodes currently being used
the number of free inodes
the percentage of the inodes that is currently being used

NOTE: The view mode you select is saved between sessions with the Filesystem Manager.

To display the number of blocks used in a directory, use du(1M) from the UNIX command line:

du directory

The optional directory must be the name of a directory in a mounted filesystem. If you do not give a directory name, du displays the number of blocks in the current directory. (du reports the value in 512-byte blocks by default; to display the value in 1024-byte blocks, include the -k option.)

For example, to display the number of blocks used in the directory /usr/james, enter:

du /usr/james

The command displays the name of each directory in the /usr/james directory and the number of blocks used.

Use the -a option to display each file in the specified directory; -s displays the grand total for the directory. For example, enter the following for the total number of blocks in /usr/james:

du -s /usr/james

You see:

   49790	/usr/james

To display a list of users and the number of blocks they own, use quot(1M) from the UNIX command line:

quot filesystem

For example, to display the owners of files in /dev/usr, enter:

quot /dev/usr

The command displays the users who have files in the filesystem and the numbers of blocks in these files:

   /dev/usr:
   74534   james
   49262   johnd
   36506   root
   15470   bin
