NAME

SYNOPSIS

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

DESCRIPTION

16       clri  writes  zeros on the inodes with the decimal i-number on the file
17       system stored on  special. After  clri, any blocks in the affected file
18       show up as missing in an  fsck(1M) of special.
19
20
21       Read  and  write  permission  is  required on the specified file system
22       device. The inode becomes allocatable.
23
24
25       The primary purpose of this routine is to remove a file that  for  some
26       reason appears in no directory. If it is used to zap an inode that does
27       appear in a directory, care should be taken to track down the entry and
28       remove  it.  Otherwise, when the inode is reallocated to some new file,
29       the old entry will still point to that file. At  that  point,  removing
30       the old entry will destroy the new file. The new entry will again point
31       to an unallocated inode, so the whole cycle is likely  to  be  repeated
32       again and again.
33
34
35       dcopy is a symbolic link to clri.

OPTIONS

38       -F FSType    Specify  the   FSType  on  which  to  operate. The  FSType
39                    should either be specified here or  be  determinable  from
40                    /etc/vfstab  by matching  special with an entry in the ta‐
41                    ble, or by consulting /etc/default/fs.
42
43
44       -V           Echo the complete command line, but  do  not  execute  the
45                    command.  The  command  line  is  generated  by  using the
46                    options and arguments provided by the user and  adding  to
47                    them  information  derived  from  /etc/vfstab. This option
48                    should be used to verify and validate the command line.
