quot - summarize file system ownership

quot [ option ] ... [ filesystem ]

Quot prints the number of blocks in the named filesystem currently owned by each user. If no filesystem is named, a default name is assumed. The following options are available:

Cause the pipeline ncheck filesystem | sort +0n | quot -n filesystem to produce a list of all files and their owners.
Print three columns giving file size in blocks, number of files of that size, and cumulative total of blocks in that size or smaller file.
Print count of number of files as well as space owned by each user.

Default file system varies with system.
/etc/passwd to get user names

ls(1), du(1)

Holes in files are counted as if they actually occupied space.
