This flag only functions within the scope of index selection or snapshot selection.


Beginning with Curator v3, --prefix is interpreted as part of a regular expression pattern. This means that if you specify --prefix l, it will match indices or snapshots named, logstash, local, l-2015.03.05, or anything that begins with the letter l. The --suffix flag exhibits similar behavior, but with the pattern matching the end of the line instead.


  • --prefix Prefix that indices or snapshots must match.


Show indices beginning with the letter l :

curator show indices --prefix l
