System Administration Commands                           clri(1M)



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 con-
                  sulting /etc/default/fs.


     -V           Echo the complete command line, but do not exe-
                  cute the command. The command line is generated
                  by using the options and arguments 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.
