A newer version is available. For the latest information, see the current release documentation.
New in Curator version 3, exit codes will indicate success or failure.
Up until Curator version 3.2.0, exit code
99 existed. This indicated
that there were no matching indices to act on, but otherwise no failure existed.
A warning message that no matching indices were found is still shown, but
Curator now returns exit code 0.
