19 This command is used to verify that module header parity and CRC
|
|
|
20 value of one or more modules on a file (standard input) are correct.
|
|
|
21 Module(s) are read from standard input, and messages will be sent to
|
|
|
22 the standard error path.

|
25 If the -u (update) option is specified, the module(s) will be copied
|
|
140
|
26 to the standard output path with the module's header parity and CRC
|
|
|
27 values replaced with the computed values. A message will be
|
|
|
28 displayed to indicate whether or not the module's values matched
|
|
|
29 those computed by VERIFY.
|
|
|
30 </para>
|
|
|
31 <para>
|
|
|
32 If the option is NOT specified, the module will not be copied to
|
|
|
33 standard output. VERIFY will only display a message to indicate
|
|
|
34 whether or not the module's header parity and CRC matched those
|
|
|
35 which were computed.
