we have a lengthy pipeline. but we also some of the files which don’t require any build/test. What is the best way to determine something in step1 and then bypass the rest of the steps? Is conditional the way to go? Can i make `groups` run or not run conditionally? Any other methods? thanks ---

Hey @js-cb! Thanks for reaching out 👋 Conditionals/groups can definitely be used - you could also combine that with the Buildkite agent’s [outcome](https://buildkite.com/docs/pipelines/conditionals#conditionals-in-steps) functionality to check on the outcome of step1 (either will be passed/hard\_failed/soft\_failed) to then determine what your pipeline does post the check (dynamic upload/more steps etc). Hope this helps! ---

The `outcome` is not very desirable because I have to get down to the command level for every single step and add that Group conditional is a good route for me. Can I make my initial step define an ENV var (based on a full build being required or not) and then use that in the `if` attribute of the next group? ---

You can definitely use an environment variable to pass on to that initial step in an `if` conditional: you’ll need to interpolate it at runtime with `SS` or `\S` (for example `$$EXAMPLE_VAR == "foo"` You can also use the `outcome` functionality with group keys if it assists also: for example should you have a group with a label `group1` - you can get its outcome just like a step: ```auto steps: - group: "Group example" key: "group1" steps: - label: ":wave: First wave" key: wave_1 command: "echo 'Hello - first!'" - label: ":wave: Second wave" key: wave_2 command: "echo 'Hello - second!'" depends_on: - wave_1 - command: | if [$$(buildkite-agent step get "outcome" --step "group1") == "passed"]; then buildkite-agent pipeline upload buildkite-example.yml fi depends_on: - group1 ``` Hope this helps! ---

Happy to hear! Its that dynamic upload in the recommendation that holds power in the conditional: you could further upload more groups/different pipelines based on outcomes, which then you could repeat this for various pipelines and such 👍
