- check software distributions
SYNOPSIS
Bq Fl airsx
Bq Fl d Ar dir
Bq Fl n Ar name
Bq Fl t Ar type
file ...
DESCRIPTION
The
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 )
EXIT STATUS
The
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.
