dcheck(8) System Manager's Manual dcheck(8)Name
dcheck - check directory consistency
Syntax
/etc/dcheck [ -i numbers ] [ filesystem ]
Description
The command is obsoleted for normal consistency checking by
The command reads the directories in a file system and compares the link-count in each i-node with the number of directory entries by which
it is referenced. If the file system is not specified, a set of default file systems is checked.
The -i flag is followed by a list of i-numbers; when one of those i-numbers turns up in a directory, the number, the i-number of the direc-
tory, and the name of the entry are reported.
The program is fastest if the raw version of the special file is used, since the i-list is read in large chunks.
Diagnostics
When a file turns up for which the link-count and the number of directory entries disagree, the relevant facts are reported. Allocated
files which have 0 link-count and no entries are also listed. The only dangerous situation occurs when there are more entries than links.
If entries are removed, so the link-count drops to 0, the remaining entries point to nothing. They should be removed. When there are more
links than entries, or there is an allocated file with neither links nor entries, some disk space may be lost but the situation will not
degenerate.
Restrictions
Since is inherently two-pass in nature, extraneous diagnostics may be produced if applied to active file systems.
Files
Default file systems vary with installation.

How would one find and list all links in a file system? My situation is

links... (3 Replies)
