CKDIST(1) BSD General Commands Manual CKDIST(1)NAMEckdist — check software distributions
SYNOPSISckdist [-airsx] [-d dir] [-n name] [-t type] file ...
DESCRIPTION
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 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).
EXIT STATUS
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.
