icheck - file system storage consistency check SYNOPSIS
icheck [ -s ] [ -b numbers ] [ filesystem ] DESCRIPTION
Icheck examines a file system, builds a bit map of used blocks, and compares this bit map against the free list maintained on the file sys- tem. If the file system is not specified, a set of default file systems is checked. The normal output of icheck includes a report of The total number of files and the numbers of regular, directory, block special and character special files. The total number of blocks in use and the numbers of single-, double-, and triple-indirect blocks and directory blocks. The number of free blocks. The number of blocks missing; i.e. not in any file nor in the free list. The -s option causes icheck to ignore the actual free list and reconstruct a new one by rewriting the super-block of the file system. The file system should be dismounted while this is done; if this is not possible (for example if the root file system has to be salvaged) care should be taken that the system is quiescent and that it is rebooted immediately afterwards so that the old, bad in-core copy of the super- block will not continue to be used. Notice also that the words in the super-block which indicate the size of the free list and of the i- list are believed. If the super-block has been curdled these words will have to be patched. The -s option causes the normal output reports to be suppressed. Following the -b option is a list of block numbers; whenever any of the named blocks turns up in a file, a diagnostic is produced. Icheck is faster if the raw version of the special file is used, since it reads the i-list many blocks at a time. FILES
Default file systems vary with installation. SEE ALSO
dcheck(1), ncheck(1), filsys(5), clri(1) DIAGNOSTICS
For duplicate blocks and bad blocks (which lie outside the file system) icheck announces the difficulty, the i-number, and the kind of block involved. If a read error is encountered, the block number of the bad block is printed and icheck considers it to contain 0. `Bad freeblock' means that a block number outside the available space was encountered in the free list. `n dups in free' means that n blocks were found in the free list which duplicate blocks either in some file or in the earlier part of the free list. BUGS
Since icheck is inherently two-pass in nature, extraneous diagnostics may be produced if applied to active file systems. It believes even preposterous super-blocks and consequently can get core images. ICHECK(1M)

quot - summarize file system ownership SYNOPSIS
quot [-acfhnv] filesystem... quot -a [-cfhnv] DESCRIPTION
quot displays the number of blocks (1024 bytes) in the named filesystem (one or more) currently owned by each user. There is a limit of 2048 blocks. Files larger than this will be counted as a 2048 block file, but the total block count will be correct. OPTIONS
The following options are supported: -a Generate a report for all mounted file systems. -c Display three columns giving a file size in blocks, the number of files of that size, and a cumulative total of blocks containing files of that size or a smaller size. -f Display three columns giving, for each user, the number of blocks owned, the count of number of files, and the user name. This option is incompatible with the -c and -v options. -h Estimate the number of blocks in the file. This does not account for files with holes in them. -n Attach names to the list of files read from standard input. quot -n cannot be used alone, because it expects data from standard input. For example, the pipeline ncheck myfilesystem | sort +0n | quot -n myfilesystem will produce a list of all files and their owners. This option is incompatible with all other options. -v In addition to the default output, display three columns containing the number of blocks not accessed in the last 30, 60, and 90 days. OPERANDS
filesystem mount-point of the filesystem(s) being checked USAGE
See largefile(5) for the description of the behavior of quot when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes). EXIT STATUS
0 Successful operation. 32 Error condition (bad or missing argument, bad path, or other error). FILES
