Hello! I’m trying to get the pull request number and detect if I’m on a pull request on a build. When I look at the docs of the env vars: [https://circleci.com/docs/environment-variables/](https://circleci.com/docs/environment-variables/) I see: `CI__PULL_REQUEST` to know I’m on a pull request `CIRCLE_PR_NUMBER` to know the PR number I’m into But none works. Any clue? ---

Hm, it should be. Do you happen to have a link to a public build or a circle.yml we could take a look at? ---

Nop, its private and I’m using only the build steps on the interface, no .yml Here are the tests parameters: ```auto wget http://repo1.maven.org/maven2/org/codehaus/sonar/runner/sonar-runner-dist/2.4/sonar-runner-dist-2.4.zip unzip sonar-runner-dist-2.4.zip if ["$CIRCLE_PULL_REQUEST" = true]; then sonar-runner-2.4/bin/sonar-runner -e -Dsonar.analysis.mode=preview -Dsonar.github.pullRequest=$CIRCLE_PR_NUMBER -Dsonar.github.repository=$REPO_SLUG -Dsonar.github.oauth=$GITHUB_TOKEN -Dsonar.login=$SONAR_LOGIN -Dsonar.password=$SONAR_PASS -Dsonar.host.url=$SONAR_HOST_URL; fi ``` I tried also with `$CI_PULL_REQUEST` If condition is never filled ---

Something I ran into that may be your issue, env varibles arn’t bool, they are stored as string. See if comparing to ‘true’ helps. ---

Thanks for your answer, but I’m unlucky nothing worked out, tried: ```auto if ["$CI_PULL_REQUEST" = "true"]; if ["$CIRCLE_PULL_REQUEST" = "true"]; if ["$CI_PULL_REQUEST" = true]; if ["$CIRCLE_PULL_REQUEST" = true]; ``` ---

Sorry i didnt catch this before, but im pretty sure you should not be putting the varible in quotes. Ref [Is it possible to run deploy section with out the build](https://discuss.circleci.com/t/is-it-possible-to-run-deploy-section-with-out-the-build/525/2?u=drazisil) ---

Strange thing is that: ```auto if ["$CIRCLE_BRANCH" = "develop"]; ``` Works fine ---

Its possible that its not working and a bug needs to be filed. I would test with echo `$CI_PULL_REQUEST` to see if/what it is getting set to. ---

Thanks for your help, tried with: ```auto if [$CI_PULL_REQUEST = "true"]; if [$CIRCLE_PULL_REQUEST = "true"]; ``` None works 😕 ---

What does the echo command get you? ---

Thanks, more info here: ```auto echo $CI_PULL_REQUEST; https://github.com/dial-once/service-devices/pull/20 ``` So I have to parse it and extract the number to get the PR number, because it will never be true. Should have tested more, thanks ---

So final code is (because $CIRCLE\_PR\_NUMBER don’t work outside of forks it seems): Check if it is a pull request: ```auto if [-z "$CIRCLE_PULL_REQUEST"]; ``` Get PR number: ```auto echo ${CIRCLE_PULL_REQUEST##*/} ``` ---

Glad that you solved this. We actually suggest using ```auto if [[! -z $CIRCLE_PULL_REQUEST]] ; then ; fi ``` but that should have the same effect. ---

these are only available for forked builds ☹ I’ve opened a separate discussion to get a few ENV’s accessible to non-forked repo builds. ---
