clri(1M) clri(1M)

NAME

clri - clear inode

SYNOPSIS

/usr/sbin/clri

special i-number ...

DESCRIPTION

The

clri 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

clri is executed, all blocks in the affected ﬁle show up as "missing" in an

fsck 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 direc-

tory. 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,

clri is likely to be ineffective.

DEPENDENCIES

clri operates only on ﬁle systems of type hfs.
