NAME

       fsck.cpm - check a CP/M file system

SYNOPSIS .

       fsck.cpm [-f format] [-n] image

DESCRIPTION .

       fsck.cpm  is used to check and repair a CP/M file system.  After reading the directory, it
       makes two passes.  The first pass checks extent fields for  range  and  format  violations
       (bad  status,  extent  number, last record byte count, file name, extension, block number,
       record count, size of .COM files, time stamp format, invalid password characters,  invalid
       time  stamp  mode).  The second pass checks extent connectivity (multiple allocated blocks
       and duplicate directory entries).

       fsck.cpm can not yet repair all errors.

OPTIONS .

       -f format
              Use the given CP/M disk format instead of the default format.

       -n     Open the file system read-only and do not repair any errors.

RETURN VALUE .

       Upon successful completion, exit code 0 is returned.

ERRORS .

       Any errors are indicated by exit code 1.

FILES .

       /etc/cpmtools/diskdefs   CP/M disk format definitions

DIAGNOSTICS .

       image: used/total files (n.n%
              non-contiguous), used/total blocks" No inconsistencies could be found.  The  number
              of  used  files  actually is the number of used extents.  Since a file may use more
              than one extent, this may be greater than the actual number of files, but a correct
              measure would not reflect how many files could still be created at most.  A file is
              considered fragmented, if sequential data blocks pointed to by the same  extent  do
              not  have  sequential block numbers.  The number of used blocks includes the blocks
              used for system tracks and the directory.
