This feature is new in the Software Express pilot program. This feature is included in the Solaris 10 3/05 release.
The netstat command displays the contents of certain network-related data structures in various formats, depending on the options that you select. The -s, -i and -m options now support an “interval.” With the specification of an optional interval, the output is continuously displayed in interval seconds until interrupted by the user. If a “count” is specified after “interval,” the output iterates for “count” times only. The “interval” and “count” must both be positive integers.
For further information, see the netstat(1M) man page.
