FSCK.CPM(1) User commands FSCK.CPM(1) NAME .. fsck.cpm - check a CP/M file system SYNOPSIS . fsck.cpm [-f format] [-n] [-u] 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, in- valid 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. -u Show all CP/M file names in upper case. 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 ac- tually 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 frag- mented, 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. AUTHORS . This program is copyright 1997-2023 Michael Haardt <michael@moria.de>.
