Sometimes, we need to get Jira key for a later usage.
For example, we can need it to do sme release notes, or other thing.
This is the regex that I use with an example of usage.
You need to replace PRJ by your project:
Extract Jira key from all commit between 2 tags:
git log rs420..rs422 --pretty=oneline | grep -oE '((PRJ-)+([0-9]*)?)' | sort -u
This permit to obtain the clear list like:
PRJ-4056 PRJ-4057 PRJ-4105 PRJ-4189
The job is done, very easily and can be used for a lot of things like interacting with Jira API if needed.
