clri - Clears i-nodes
The clri command is obsoleted for normal file system repair work by the
The clri command writes zeros on the i-nodes with the decimal i-numbers on
the specified filesystem. After clri has finished its work, any blocks in
the affected file are defined as "missing" when you run icheck on the
Read and write permission is required on the specified file system device.
The i-node becomes allocatable.
The primary purpose of this routine is to remove a file which does not
appear in any directory. If you use the command to remove an i-node which
does appear in a directory, take care to track down the entry and remove
it. Otherwise, when the i-node is reallocated to some new file, the old
entry will still point to that file. If you then remove the old entry, you
will destroy the new file, and the new entry will again point to an unallo-
cated i-node. Consequently, the entire cycle repeats itself. #ifdef
You must be root to use this command. #endif
If the file is open, clri is likely to be ineffective.
