.SH DESCRIPTION \"{{{
\fBfsck.cpm\fP 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).
.P
\fBfsck.cpm\fP can not yet repair all errors.
.\"}}}
.SH OPTIONS \"{{{
.IP "\fB\-f\fP \fIformat\fP"
Use the given CP/M disk \fIformat\fP instead of the default format.
.IP "\fB\-T\fP \fIlibdsk-type\fP"
libdsk driver type, e.g. \fBtele\fP for Teledisk images or \fBraw\fP for raw images 
(requires building cpmtools with support for libdsk).
.IP "\fB\-n\fP"
Open the file system read-only and do not repair any errors.
.\"}}}
.SH "RETURN VALUE" \"{{{
Upon successful completion, exit code 0 is returned.
.\"}}}
.SH ERRORS \"{{{
Any errors are indicated by exit code 1.
.\"}}}
.SH FILES \"{{{
@DATADIR@/diskdefs	CP/M disk format definitions

.SH ENVIRONMENT \"{{{

.SH DIAGNOSTICS \"{{{
.IP "\fIimage\fP: \fIused\fP/\fItotal\fP files (\fIn\fP.\fIn\fP% non-contiguos), \fIused\fP/\fItotal\fP 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.
