BITBUCKET_COMMIT variable - short (7digits) in pipelines

[dev-mp]

I would like to use 'BITBUCKET_COMMIT' variable in pipelines to create unique file name. The problem is, that 40-digits SHA is not convinient to use in file names.

Is it possible to use 7-digits SHA environment variables? Or any way to process it in YAML?

Hi Milosz,

You can truncate the BITBUCKET_COMMIT variable inside of your pipeline script.

For example:

pipelines:
  default:
    - step:
        script:
          - export BITBUCKET_COMMIT_SHORT=$(echo $BITBUCKET_COMMIT | cut -c1-7)
          - ...

You can see other examples of how to do this here: https://stackoverflow.com/questions/8928224/trying-to-retrieve-first-5-characters-from-string-in-bash-error

Thanks,

Phil

Would be easier if pipelines would that work already for us. Also, for pipelines it would be easy to use git commands instead of bash tricks. Git has a "safety" mechanism that will make the short commit hashes it hands out longer if the default 7 chars are not unique.

As a quick ref, this works too for at least bash

export BITBUCKET_COMMIT_SHORT="${BITBUCKET_COMMIT::7}"

Agree with @Alexander Weickmann

You can get your git commit pretty format with the following:

- export COMMIT=$(git log --pretty=format:'%h' -n 1)
