NAME

clri − clear inode

SYNOPSIS

/etc/clri file-system i-number ... 

DESCRIPTION

clri writes zeros on the inode numbered i-number. file-system must be a special file name referring to a device containing a file system.  For proper results, file-system should not be mounted.  After clri is executed, any blocks in the affected file show up as “missing” in an fsck(1M) of the file-system. This command should only be used in emergencies, and extreme care should be exercised.

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

The primary purpose of this command is to remove a file which for some reason appears in no directory.  If it is used to zero out an inode that does appear in a directory, care should be taken to locate 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 destroys the new file, causing the new entry to point to an again unallocated inode with the likelihood that the whole cycle will be repeated. 

WARNINGS

If the file system is mounted, clri is likely to be ineffective.
