disk space occupied by each user
is used to gather statistics about the disk
usage for each local user.
The options are as follows:
- Include statistics for all mounted filesystems.
- Display three columns containing number of blocks per file,
number of files in this category, and aggregate total of blocks in files
with this or lower size.
- For each user, display count of files and space
- Estimate the number of blocks in each file based on its
size. Despite that this doesn't give the correct results (it doesn't
account for the holes in files), this option isn't any faster and thus is
- By default, all sizes are reported in 512-byte block
counts. The -k options causes the numbers to
be reported in kilobyte counts.
- Given a list of inodes (plus some optional data on each
line) in the standard input, for each file print out the owner (plus the
remainder of the input line). This is traditionally used in the pipe:
to get a report of files and their owners.
# ncheck filesystem | sort -n | quot -n filesystem
- In addition to the default output, display the number of
files not accessed within 30, 60 and 90 days.
- If the environment variable
BLOCKSIZE is set, and the
-k option is not specified, the block counts
will be displayed in units of that size block.
