Synopsis

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

Availability

SUNWcsu

Description

clri writes zeros on the inodes with the decimal i-number on the filesystem stored on special. After clri, any blocks in the affected file will 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 which for some reason appears in no directory. If it is used to zap an inode which 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 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.
