.Sh NAME
.Nm ckdist
.Nd check software distributions
.Sh SYNOPSIS
.Nm ckdist
.Bq Fl airsx
.Bq Fl d Ar dir
.Bq Fl n Ar name
.Bq Fl t Ar type
.Ar
.Sh DESCRIPTION
The
.Nm
utility reads "checksum" files (which are assumed to specify components
of a software distribution) and verifies the integrity of the
distribution by validating the checksum of each component file.
Both MD5 (128-bit "message digest") and .inf (32-bit CRC) checksum
formats are supported.
.Pp
The
.Ar file
operands may refer to regular files or to directories. Regular files
named "md5", or which have an ".md5" or an ".inf" extension, are
assumed to be of the implied type, otherwise format is determined from
content. If a directory is specified, it is searched for
appropriately-named files only.
.Pp
Options are as follows:
.Bl -tag -width 8n -offset indent
.It Fl a
Report on all distribution components, not just those in respect of
which errors are detected.
.It Fl i
Ignore missing distribution components.
.It Fl r
Search specified directories recursively.
.It Fl s
Suppress complaints about inaccessible checksum files and directories.
.It Fl x
Verify the existence of distribution components (and also check sizes,
in the case of .inf files), but omit the more time-consuming step of
actually computing and comparing checksums.
.It Fl d Ar dir
Look for distribution components in the directory
.Ar dir .
.It Fl n Ar name
Access distribution components using the filename
.Ar name .
When accessing .inf file components, append the appropriate
extension to the filename.
.It Fl t Ar type
Assume that all specified checksum files are of the format
.Ar type ,
and search directories only for files in this format (where
.Ar type
is either "md5" or "inf").
.El
.Sh SEE ALSO
cksum(1), md5(1)
.Sh DIAGNOSTICS
Exit status is 0 if no errors were detected, 1 if errors were found in
a distribution, and 2 if usage errors, inaccessible input files, or
other system errors were encountered.
.Sh NOTES
Both BSD and DOS versions of
.Nm
are available.
