*Pre-Release* ^{Twin^^Peaks}

.Alive *download the pre-release code*

Description

Attempts to contact the target specified in the contents of variable %Alive%.  Provides several essential pieces of information in a flexible way to allow self-documenting usage.

1. Expands the input variable at runtime so complex statements can be created easily.
2. Filters success messages to STDOUT, failure messages to STDERR.
3. Sets an errorlevel to allow custom formatting of the output.

Examples, Notes and Instructions

• %.Alive% is a ^{Twin^^Peaks} Mt/\Cmd.  This means that it is a two step command.  Load the input parameter, then run the command.

SET "Alive=[IPAddress|FullyQualifiedDNSName|NetBiosName]" %.Alive%

• Since all ^{Twin^^Peaks} commands dynamically expand their input variable at runtime, you can place both commands on the same line, or within the same complex statement (see the examples below).
• When the target is found, a success message is sent to STDOUT.  When it is not found, an error message is sent to STDERR.  This lets you display only what you want to see.

Example 1 Scan an entire subnet

This command will check all addresses from 10.7.7.10 through 10.7.7.254

Example 2 Check a subnet, show only the addresses that respond.

Same as above but using the .Kity (Keep-It-To-Yourself) command to filter out anything sent to STDERR.

Example 3 Check the local network, display the names of systems that are not accessible.

Using the output from the escaped version of .NetView, test each machine.  If you find it, keep Quiet.  If not, display the machine name.

Example 4 Check a list of machines from a text file.

Example 5 At the command line.
