Y + L TOPS-20 CHECKD
CHECKD is a program to check the filesystem and bittable for consistent
data. CHECKD is also capable of rebuilding the bittable from the
directory information and of scanning for files which use particular
disk addresses. Commands are in the general form:
Keyword [optional arg] structure-name
Command Description
------- -----------
CHECK BITTABLE Check the consistency of the bit table by comparing
the pages marked as assigned against those pointed to
by the file system. Also writes lost page addresses
in a file.
CHECK DIRECTORY Check just directory information on the specified
structure.
REBUILD Rebuild bittable from directory information on the
specified structure.
RECONSTRUCT Reconstucts the <ROOT-DIRECTORY> on the specified
structure and then rebuilds the bit table.
CREATE Accepts configuration information for a file
structure and then creates a new file system on the
specified units.
SCAN Read a file of disk addresses and then scan the
directories for the specified addresses. When each
address is found, prints the name of the file that
uses that address.
EXIT Exit from CHECKD.
RELEASE Deassign the pages whose addreses are contained
in the specified file.
