.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility reads
|
|
.Dq 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
|
|
.Dq "message digest" )
|
|
and
|
|
.Pa .inf
|
|
(32-bit CRC) checksum
|
|
formats are supported.
|
|
.Pp
|
|
The
|
|
.Ar file
|
|
operands may refer to regular files or to directories.
|
|
Regular files
|
|
named
|
|
.Pa md5 ,
|
|
or which have an
|
|
.Pa .md5
|
|
or an
|
|
.Pa .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.
|
|
.Pp
|
|
The options are as follows:
|
|
.\"Bl -tag -width ".Fl n Ar name"
|
|
.Bl -tag -width 8n -offset indent
|
|
.It Fl a
|
|
Report on all distribution components, not just those in respect of
|
|
which errors are detected.
|
|
.It Fl i
|
|
Ignore missing distribution components.
|
|
.It Fl r
|
|
Search specified directories recursively.
|
|
.It Fl s
|
|
Suppress complaints about inaccessible checksum files and directories.
|
|
.It Fl x
|
|
Verify the existence of distribution components (and also check sizes,
|
|
in the case of
|
|
.Pa .inf
|
|
files), but omit the more time-consuming step of
|
|
actually computing and comparing checksums.
|
|
.It Fl d Ar dir
|
|
Look for distribution components in the directory
|
|
.Ar dir .
|
|
.It Fl n Ar name
|
|
Access distribution components using the filename
|
|
.Ar name .
|
|
When accessing
|
|
.Pa .inf
|
|
file components, append the appropriate
|
|
extension to the filename.
|
|
.It Fl t Ar type
|
|
Assume that all specified checksum files are of the format
|
|
.Ar type ,
|
|
and search directories only for files in this format (where
|
|
.Ar type
|
|
is either
|
|
.Cm md5
|
|
or
|
|
.Cm inf ) .
|
|
.El
|
|
.Sh EXIT STATUS
|
|
The
|
|
.Nm
|
|
utility exits with one of the following values:
|
|
.Bl -tag -width indent
|
|
.It 0
|
|
No errors were detected.
|
|
.It 1
|
|
Errors were found in a distribution.
|
|
.It 2
|
|
Usage errors, inaccessible input files, or
|
|
other system errors were encountered.
