     ckdist -- check software distributions


     ckdist [-airsx] [-d dir] [-n name] [-t type] file ...


     The ckdist 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

     The 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.

     Options are as follows:

	   -a	     Report on all distribution components, not just those in
		     respect of which errors are detected.

	   -i	     Ignore missing distribution components.

	   -r	     Search specified directories recursively.

	   -s	     Suppress complaints about inaccessible checksum files and

	   -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 com-
		     paring checksums.

	   -d dir    Look for distribution components in the directory dir.

	   -n name   Access distribution components using the filename name.
		     When accessing .inf file components, append the appropri-
		     ate extension to the filename.

	   -t type   Assume that all specified checksum files are of the for-
		     mat type, and search directories only for files in this
		     format (where type is either "md5" or "inf").


     cksum(1), md5(1)


     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.


     Both BSD and DOS versions of ckdist are available.
