openSolaris 2008 - Checking the Size of Directories - System Administration Guide: Advanced Administration

Checking the Size of Directories

You can display the size of directories by using the du command and options. Additionally, you can find the amount of disk space used by user accounts on local UFS file systems by using the quot command. For more information about these commands, see the du(1) and quot(1M) man pages.

How to Display the Size of Directories, Subdirectories, and Files

Display the size of one or more directories, subdirectories, and files by using the du command. Sizes are displayed in 512-byte blocks.
```
$ du [-as] [directory ...]
```
du

Displays the size of each directory that you specify, including each subdirectory beneath it.

-a

Displays the size of each file and subdirectory, and the total number of blocks that are contained in the specified directory.

-s

Displays the total number of blocks that are contained in the specified directory.

-h

Displays the size of each directory in 1024–byte blocks.

-H

Displays the size of each directory in 1000–byte blocks.

[directory ...]

Identifies one or more directories that you want to check. Separate multiple directories in the command-line syntax with spaces.

Example 6-8 Displaying the Size of Directories, Subdirectories, and Files

The following example shows the sizes of two directories.

$ du -s /var/adm /var/spool/lp
130     /var/adm
40      /var/spool/lp

The following example shows the sizes of two directories and includes the sizes of all the subdirectories and files that are contained within each directory. The total number of blocks that are contained in each directory is also displayed.

$ du /var/adm /var/spool/lp
2       /var/adm/exacct
2       /var/adm/log
2       /var/adm/streams
2       /var/adm/acct/fiscal
2       /var/adm/acct/nite
2       /var/adm/acct/sum
8       /var/adm/acct
2       /var/adm/sa
2       /var/adm/sm.bin
258     /var/adm
4       /var/spool/lp/admins
2       /var/spool/lp/requests/printing.Eng.Sun.COM
4       /var/spool/lp/requests
4       /var/spool/lp/system
2       /var/spool/lp/fifos
24      /var/spool/lp

The following example shows directory sizes in 1024–byte blocks.

$ du -h /usr/share/audio
 796K   /usr/share/audio/samples/au
 797K   /usr/share/audio/samples
 798K   /usr/share/audio

How to Display the User Ownership of Local UFS File Systems

Become superuser or assume an equivalent role.
Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.
Display users, directories, or file systems, and the number of 1024-byte blocks used.
```
# quot [-a] [filesystem ...]
```
-a

Lists all users of each mounted UFS file system and the number of 1024-byte blocks used.

filesystem

Identifies a UFS file system. Users and the number of blocks used are displayed for that file system.

Note - The quot command works only on local UFS file systems.

Example 6-9 Displaying the User Ownership of Local UFS File Systems

In the following example, users of the root (/) file system are displayed. In the subsequent example, users of all mounted UFS file systems are displayed.

# quot /
