clri(1M) clri(1M) NAME
clri - clear inode SYNOPSIS
special i-number ... DESCRIPTION
The command clears the inode i-number by filling it with zeros. special must be a special file name referring to a device containing a file system. For proper results, special should not be mounted (see WARNINGS below). After is executed, all blocks in the affected file show up as "missing" in an of special (see fsck(1M)). This command should only be used in emergencies. Read and write permission is required on the specified special device. The inode becomes allocatable. WARNINGS
The primary purpose of this command is to remove a file that for some reason does not appear in any directory. If it is used to clear 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 in the directory 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 unallocated inode, so the whole cycle is likely to be repeated again. If the file system is mounted, is likely to be ineffective. DEPENDENCIES
operates only on file systems of type SEE ALSO
fsck(1M), fsdb(1M), ncheck(1M). STANDARDS CONFORMANCE
