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.
