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 supported.
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.
The 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
directories.
-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.
-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 appropriate extension to the filename.
-t
type
- Assume that all specified checksum files are of the format
type, and search directories only for files in this
format (where type is either
md5
or inf
).
The ckdist
utility exits with one of the following
values:
- 0
- No errors were detected.
- 1
- Errors were found in a distribution.
- 2
- Usage errors, inaccessible input files, or other system errors were
encountered.
Both BSD and DOS versions of
ckdist
are available.
