NAME

       clri - Clears i-nodes

SYNOPSIS

       /usr/sbin/clri filesystem i-number ...

DESCRIPTION

       The clri command is obsoleted for normal file system repair work by the fsck command.

       The clri command writes zeros on the i-nodes with the decimal i-numbers on the specified filesystem.  After clri has finished its work, any
       blocks in the affected file are defined as "missing" when you run icheck on the filesystem.

       Read and write permission is required on the specified file system device.  The i-node becomes allocatable.

       The primary purpose of this routine is to remove a file which does not appear in any directory.	If you use the command to remove an i-node
       which  does  appear in a directory, take care to track down the entry and remove it.  Otherwise, when the i-node is reallocated to some new
       file, the old entry will still point to that file.  If you then remove the old entry, you will destroy the new file, and the new entry will
       again point to an unallocated i-node.  Consequently, the entire cycle repeats itself.

       You must be root to use this command.

       If the file is open, clri is likely to be ineffective.

NAME

       clri, dcopy - clear inode

SYNOPSIS

       clri [-F FSType] [-V] special i-number

       dcopy [-F FSType] [-V] special i-number

DESCRIPTION

       clri  writes  zeros  on the inodes with the decimal i-number on the file system stored on  special. After  clri, any blocks in the affected
       file show up as missing in an  fsck(1M) of special.

       Read and write permission is required on the specified file system device. The inode becomes allocatable.

       The primary purpose of this routine is to remove a file that for some reason appears in no directory. If it is used to zap  an  inode  that
       does  appear  in  a directory, care should be taken to track down the entry and remove it. Otherwise, when the inode is reallocated to some
       new file, the old entry will still point to that file. At that point, removing the old entry will destroy the new file. The new entry  will
       again point to an unallocated inode, so the whole cycle is likely to be repeated again and again.

       dcopy is a symbolic link to clri.

OPTIONS

       -F FSType    Specify  the   FSType on which to operate. The  FSType should either be specified here or be determinable from  /etc/vfstab by
		    matching  special with an entry in the table, or by consulting /etc/default/fs.

       -V	    Echo the complete command line, but do not execute the command. The command line is generated by using the options	and  argu-
		    ments  provided  by the user and adding to them information derived from /etc/vfstab. This option should be used to verify and
		    validate the command line.

USAGE

       See largefile(5) for the description of the behavior of clri and dcopy when encountering files greater than or equal  to  2  Gbyte  (  2^31
       bytes).
