_rc - UDM Built-in Variable


The _rc built-in variable holds the current UDM return code, a numeric value that indicates the highest return code received from processing all UDM commands up to that point.

The value of _rc is the return code that the UDM Manager returns when it exits.

As with the _halton variable, _rc can be set, via the set command, to any of the following integers or convenience values:

0 / none

Success or no error.

4 / warn

Warning has been issued.

8 / error

Error has occurred.

16 / fatal error

Fatal error has occurred.


For example:

set _rc=warn
