+.Sh NAME
+.Nm clri
+.Nd clear an inode
+.Sh SYNOPSIS
+.Nm clri
+.Ar special_device inode_number ...
+.Sh DESCRIPTION
+.Bf -symbolic
+.Nm Clri
+is obsoleted for normal file system repair work by
+.Xr fsck 8 .
+.Ef
+.Pp
+.Nm Clri
+zeros out the inodes with the specified inode number(s)
+on the filesystem residing on the given
+.Ar special_device .
+The
+.Xr fsck 8
+utility is usually run after
+.Nm clri
+to reclaim the zero'ed inode(s) and the
+blocks previously claimed by those inode(s).
+Both read and write permission are required on the specified
+.Ar special_device .
+.Pp
+The primary purpose of this routine
+is to remove a file which
+for some reason is not being properly handled by
+.Xr fsck 8 .
+Once removed,
+it is anticipated that
+.Xr fsck 8
+will be able to clean up the resulting mess.
+.Sh "SEE ALSO"
+.Xr fsck 8 ,
+.Xr fsdb 8 ,
+.Xr icheck 8 ,
+.Xr ncheck 8
+.Sh BUGS
+If the file is open, the work of
+.Nm clri
+will be lost when the inode is written back to disk from the inode cache.
