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 connec-
       tivity (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.
