How should I dynamically change the limit parameter in the head command

[vaguiar]

I have a search command which pipes to "| head limit=10". But I want to let the user decide if they see 10 or 20 or all the events returned.

One way that I could think of was by adding a drop-down with specific values such as 10, 20 and 999,999,999(very large number) and by passing that value as the limit of the head command. I wonder if there's a better way to do this though.

do a drop down and pass the entire command, not just the value, like this:

<input type="dropdown" token="count_filter">
  <label>Limit your Results</label>
  <choice value="">ALL (no filter)</choice>
  <choice value="| head 10">10</choice>
  <choice value="| head 20">20</choice>
  <default>All (no filter)</default>
</input>

Then the last line of your search should be $count_filter$ (without a leading pipe). This way you do not need that "huge number" aspect.

Good point and it let's me select a default value as well. Thanks!

You could just use a text box with the header of "result count (enter whole number)" and use that token if you want them to get the number of results they desire.
