The <execNative> step has the following attributes:
userToRunAs – An optional attribute that is the name of the user to run this command. If this attribute is omitted, the command is run as the value of defaultUserToRunAs in the configuration file. The value can be either a string user name or a numeric user ID. The value should be a nonempty string. This attribute can reference simple substitution variables.
dir – An optional attribute that is the absolute path to the working directory for the command. If this attribute is omitted, the value defaults to the agent-specific configurable directory. This value should be a nonempty string. This attribute can reference simple substitution variables.
timeout – An optional attribute of type positiveInteger, which specifies the number of seconds to wait for the command to complete before timing out. If this attribute is omitted, the plan's <execNative> timeout period applies. The value should be greater than 0.
