FSCK.CPM(1) User commands 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 .
/usr/local/share/cpmtools2/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 num‐
ber 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 direc‐
tory.
