### Redis-ztrim 
Usage: node ./bin/redis-ztrim [options] pattern start stop

Trim a group of zlists matching `pattern` so that they'll contain only the specified
range of elements specified. Both start and stop are zero-based indexes,
where 0 is the first element of the list with the highest score (the head), 1 the next
element and so on.

For example: redis-ztrim foobar* 0 2 will modify the zsets matching the pattern foobar*
so that only the first three elements of each zsets will remain.

Options:
  -p, --preview  preview what is going to be deleted  [boolean]  [default: false]
  -v, --verbose  verbose mode                         [boolean]  [default: false]
  -h, --help     this message.                        [boolean]

Trim all zsets matching the pattern bringr:*:*:ua:*" so that only their members ranked from 0 to 99 will remain.

$ redis-ztrim
✔  bringr:1:121:ua:m   trimmed
✔  bringr:1:121:ua:y   trimmed
✔  bringr:1:123:ua:y   trimmed
