Event catalog pattern query fails on a Windows system

I am trying to do a pattern query for event definitions on a Windows system using the eventcatalog command. For example: eventcatalog -listdefinitions -name EVENT% -pattern. I don't get the expected results.

Cause

The percent character (%) is a reserved character in the Windows command-line interface and is not passed properly to the eventcatalog command.

Remedy

On Windows systems, you must escape the percent character character by typing %%:
eventcatalog -listdefinitions -name EVENT%% -pattern
