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 du(1) and quot(1M).

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

Example 8-7 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....
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

  1. Become superuser.
  2. 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 8-8 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 /
/dev/rdsk/c0t0d0s0:
43340   root    
 3142   rimmer   
   47   uucp    
   35   lp      
   30   adm     
    4   bin     
    4   daemon  
# quot -a
/dev/rdsk/c0t0d0s0 (/):
