fsck.cpm(1)


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.

   -T libdsk-type
          libdsk driver type, e.g. tele for Teledisk images or raw for raw
          images (requires building cpmtools with support for libdsk).

   -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-contiguos), 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  greather  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.
