fsck.cpm - check a CP/M file system
fsck.cpm [-f format] [-n] image
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.
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.
Any errors are indicated by exit code 1.

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.
