xterm Command
The command line options that you can use to customize the
xterm
command.
Separate command line options with a space. The following table lists some
valid command line options. Use the
man xterm
command to display a
complete list of command line options.
-o offset Set the offset from the beginning of the packet, where you
want to begin pattern matching, to offset bits.
-l length Set the length of the portion of the packet used for
pattern matching to length bits.
-a Display only packets that match the pattern. If you use
the
-o
and
-l
command line options, display only
packets where the pattern matches the portion of the
packet that starts offset bits from the beginning of the
packet and extends for length bits.
For example, assume that the pattern is
0xff
, the offset is
8 (bits), and the length is 8 (bits). If you use the
-a
command line option, the Sunscope utility displays only
packets that have the value
0xff
in the second byte (bits
8 through 15).
If you do not use the
-a
command line option, the
Sunscope utility displays only packets for which the
pattern does not match the portion of the packet that
starts offset bits from the beginning of the packet and
extends for length bits. For example, assume that the
pattern is
0xff
, the offset is 8 (bits), and the length is 8
(bits). If you do not use the
-a
command line option, the
Sunscope utility displays only packets that do not have
the value
0xff
in the second byte.
