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
(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:
Report on all distribution components, not just those in respect of which errors are detected.
Ignore missing distribution components.
Search specified directories recursively.
Suppress complaints about inaccessible checksum files and directories.
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.
Look for distribution components in the directory
Access distribution components using the filename
name. When accessing
.inf file components, append the appropriate extension to the filename.
Assume that all specified checksum files are of the format
type, and search directories only for files in this format (where
type is either
