I have a bitbucket pipeline where I want to retrieve some part of the branch name (the ticket name)

I basically get the branch name with :

 - BRANCH_NAME="$(git rev-parse --abbrev-ref HEAD)"

Now the branch name is like fix/DOM-123-my-ticket-info

I would like to basically do something like

 - BRANCH_NAME="$(git rev-parse --abbrev-ref HEAD)"
 - TICKET_NAME= // a way to retrieve DOM-123 from $BRANCH_NAME

Do you know how would this be possible ?

I haven"t find anything on how such a thing would be possible.

  • What are the rules for ticket names? No slashes? Are `DOM` and `my-ticket-info` fixed strings? – phd Oct 24 '22 at 13:41

If you want to run a regular expression outside your usual language/runtime, you should get used to the grep utility.

A naive approach for your case:

TICKET_NAME=$(echo $BRANCH_NAME | grep --only-matching --extended-regexp 'DOM-[0-9]+')

(you might need to workout the actual ticket name regex)

Friendly reminder: the branch name is accessible in the $BITBUCKET_BRANCH environment variable (for branch pipelines, no custom nor tag-triggered pipelines)
