NAME
       clri - clear i-node

SYNOPSIS
       /etc/clri filesystem i-number ...

DESCRIPTION
       N.B.:  _C_l_r_i is obsoleted for normal file system repair work by _f_s_c_k(8).

       _C_l_r_i writes zeros on the i-nodes with  the  decimal  _i_-_n_u_m_b_e_r_s  on  the
       _f_i_l_e_s_y_s_t_e_m_.   After  _c_l_r_i_, any blocks in the affected file will show up
       as ‘missing’ in an _i_c_h_e_c_k(8) of the _f_i_l_e_s_y_s_t_e_m_.

       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 for some
       reason appears in no directory.  If it is used to zap an  i-node  which
       does  appear  in  a  directory,  care should be taken 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.  At that point
       removing the old entry will destroy the new file.  The new  entry  will
       again  point  to an unallocated i-node, so the whole cycle is likely to
       be repeated again and again.

       icheck(8)

BUGS
       If the file is open, _c_l_r_i is likely to be ineffective.
