.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.

.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.
