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

ENVIRONMENT

       CPMTOOLSFMT     Default format

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.
